Description for K-Flex 6RXL100258

Overview:

Insul-Lock® insulation products and accessories are widely recognized by the HVACR and Plumbing wholesale trade. They offer superior product characteristics such as cold weather flexibility, durable skin surface and exacting manufacturing tolerances.

Insul-Lock® Seam-Seal pipe insulation is an environmentally friendly, CFC-free, flexible elastomeric insulation, pre-slit with a factory-applied pressure sensitive adhesive. It is black in color and identified as Insul-Lock® Seam-Seal. This superior closed cell insulation is designed to retard heat flow and prevent condensation when properly installed. Insul-Lock® Seam-Seal pipe insulation is pre-slit with a factory applied specially formulated bonding adhesive applied to both seam surfaces and comes with convenient built-in release liners which allow for easy installation. Insul-Lock® Seam-Seal has the same excellent insulation properties as standard Insul-Tube® and is used on similar applications such as refrigerant lines, cold water plumbing, roof drains and chilled water systems. Insul-Lock® Seam- Seal can be used with heat tracing/heat tapes.

Insul-Lock uses the pressure sensitive adhesive (PSA) seam-seal system. The PSA system enables the user to fit the tube over the pipe, peel back the release liner and apply pressure to close (starting at the ends and working your way to the center) to install your insulation in seconds! This system guarantees a strong, durable seal without the risk of messy adhesives that could spill.

Insul-Lock® Seam-Seal is non-porous, non-fibrous and resists mold growth. An EPA registered antimicrobial agent is incorporated into the product providing additional protection against mold, fungal and bacterial growth.

K-Flex USA elastomeric insulation products are GREENGUARD® certified as low VOC materials, meeting the requirements of the Children and Schools classification, the most stringent requirements. Additionally, all K-Flex USA elastomeric insulation products are GREENGUARD® listed for mold resistance and meet the "mold resistant" criteria.

              Comments about 1-5/8" Pipe (O.D.) x 1" Wall Insul-Lock Pipe Insulation, 6':

              I recently installed a whole house steam humidifier which uses a thick wall rubber hose to deliver the steam to discharge nozzles in the ductwork. The humidifier works great, but was losing a lot of heat through the hose. Apparently there is considerable amount of steam condensing back into liquid in the hose, and there are tables in the installation manual showing steam loss based on hose length. I was able to get by with a little over 3 feet of hose, but was still having a lot of heat loss. I measured the temperature of the outer skin of the hose at 140 deg. F with a thermocouple, and after installing the insulation, the outer temperature of the insulation was about 80 deg. F. This is a very expensive piece of insulation, but is doing a very good job for my application. I calculate it will have to save 300 KWH of electricity to break even for the cost of the insulation. In the meantime, my home is comfortable with the humidifier, and I have the perception I'm saving energy.

                    Comments about 7/8" Pipe (O.D.) x 1" Wall Insul-Lock Pipe Insulation, 6':

                    I insulated all our hot water and radiator supply pipes with this R-7 pipe insulation. This is the highest R-value pipe insulation I could find. Most of the pieces had a nice very sticky two sided edge that were covered films to remove from each side and press together to seal. It sticks tight and does not need tape too. A few of the sections had only one sticky side and then an overlapping sticky paper like covering for the seam. That was a two step process--remove the sealing film and then the overlapping film. I'm not sure which actually performs better or if they are the same--they are equally easy to install in my opinion.
                    Sizing is a bit tricky, you have to size the outside diameter of the pipe and the wall thickness of the insulation--in this case 7/8" inside opening (for 3/4" pipe) with a 1" wall. But I also used this on some 1/2" pipe since I didn't want to figure exactly what I needed for two sizes. It is a bit loose but seals just as well. Energy Star only requires R-3 but in most cases, more is better with insulation.

                          There is no comparison between this product and the cheap polyethylene foam insulation sold at big box stores. This is a serious, professional product. The reason I rated it 4 stars instead of 5 is that I received three different products when I ordered this. One was consistent with the website image: Pre-slit with adhesive. The second type I received was unslit, so I had to cut it and seal back together with contact cement. The third type I received was the best of the three. It was pre-slit but also had an adhesive flap on the outside to keep the slit sealed

                                      Appears to be Factory Replacement. Quick turn around time from online purchase to delivery. Fair price. Completely satisfied with SupplyHouse service.

                                      Too damp outside to install at moment. Critical factor in Wall Insul-Lock Pipe will be glue joint. Curious to see performance of this aspect-will update on its performance after the heat of our Texas Summers!

                                          I'm not sure what product you refer to but liquid between the tank and the
                                          system will be not flowing most of the time. If the pipe you are insulating
                                          is within the freeze zone it WILL freeze up. I believe that the insulation

                                          understand why you are running a water line to a septic system in any
                                          event. f the water is circulating rather than straight through then adding
                                          anti-freeze solution to the water will do the job.

                                          I would NOT use this type of insulation underground. Direct burial would
                                          cause the weight of the dirt to crush the soft foam like insulation reducing
                                          its insulation factor significantly. You need some type of rigid and
                                          moisture proof insulation like a Closed cell polyurethane spray foam.

                                          I used this insulation for the pipe coming off my hot water heater.
                                          They are pricey but are commercial grade. I don't know if they can be
                                          used underground but I would try it if you have a problem with freezing.

                                          This is slightly porous material, so it's not suitable for any possible wet environment. If you needed to use it underground, I'd wrap it in 6 mil or heavier poly sheet plastic, and tape it well with construction tape. Think of it sitting in a bathtub of water, and protect it against that, and you may be okay.
                                          If you use it above ground, I've had success wrapping it in heavy tin-foil, it protects it from the sun, and keeps the rain out. That would be too fragile for underground work.

                                          Rich,
                                          Unless the septic system is used only sporadically during the winter there
                                          shouldn't be an issue if the pipes are buried. There is enough heat
                                          released from the digestion in the tank to keep a lot of the plumbing much
                                          warmer than what you would imagine.
                                          However, if your system is not in regular use, or if your pipe is exposed
                                          then I can see no big issue with trying this. If you want a more
                                          professional answer I would contact the manufacturer directly, THere is
                                          quite a bit of info already if you click on the details in the PEX site
                                          under this particular size.
                                          I have done an installation where I am concerned about UV degradation
                                          because the pipes are exposed to sunlight all day. To solve this issue I
                                          spiral wrapped the foam with a UV barrier tape and so far there has been no
                                          issue.
                                          An alternate method that I have done (that is still working after 30 years)
                                          is to lay a sheet of Dow (pink) foam inulation 1" or thicker directly on
                                          top of the pipe in the trench. Backfill right over it and you should be
                                          more than good. I see -20F at least once a year. This is for my well line,
                                          which because of ledge is only under 12-18 inches of cover.
                                          Hope this helps.

                                          Generally for underground applications you might consider using a cellular glass foam insulation (Foamglas by Pittsburgh Corning) as it is not just closed-cell but rigid and waterproof and suitable for burial with some added protection. However, Foamglas is hard to find for other than industrial purposes. If you can keep Insul-Lock from PexSupply dry and protected from crushing then it might be suitable for your application. Insul-Lock is closed-cell so will not water-log, and is therefore also somewhat crush resistant but not crush proof. I would wrap Insul-Lock with a heavy duty waterproof duct tape, and pour any sort of waterproofing around the tank end and the bare end so that any water infiltration is minimized and also provide some protection against abrasion. Another approach would be to lay a 2 inch thick 18-24 inch wide styrene board above the outfall line and under existing dirt cover.
                                          I would ensure that your septic outfall connection is self-draining and worry less about insulation other than the styrene mentioned above. If your septic system is properly designed, fluid should never be languishing in your outfall line where it can freeze up. Outfall lines should be self-draining back into the tank holding the dose pump. Check valves do not belong on this line. You may need a new design for your outfall line that keeps it below the frost line or slopes it such that when the pump is off any area above the frost line drains back into the holding tank or into a section of pipe with adequate volume below the frost line to hold any backflow.

                                        Do you have something suitable for wrapping 1-1/4" and 2" steam lines right at the boiler?

                                          You may want to look into a high temperature wrapping tape near the boiler and for odd/custom installs.

                                          This will help to prevent the line from freezing. Most people will use this insulation and heat tape to stop a line from freezing.
