Description for K-Flex 6RXL038048

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.

        Great price for a good material.

        I used this to insulate mostly-exposed hot water pipes in my unfinished basement. It's fast, easy and a sharp knife provides surprisingly exact cuts. It's flexible enough to be stretched a bit to get into tight spaces between, say, the pipe and a beam. The top layer can fails and split open a bit in spots.

        I couldn't give it a full five stars because the adhesive is tricky. It works well if you connect the sides correctly to close the seam, but it can't be re-placed once stuck together. It can be pulled off the base material, especially at the end of the insulation section.

        Be careful, take your time and you should be OK.

        The 1-1/2" pipe insulation matched the 1-1/2" pex pipe dimensions on the heating pipes in the crawl space, and the adhesive tape on the insulation edges made the initial installation quick and easy. However, the adhesive joint failed to stay together within 24 hours with long gaps opening up to 2" wide. I had to install duct tape along most of the seams to keep the pipe insulation together. It took too much effort to install both insulation and then duct tape to consider using this product again.

              Bad product

              Verified Reviewer

              Comments about 1-5/8" Pipe (O.D.) x 3/8" Wall Insul-Lock Pipe Insulation, 6':

              I was extremely disappointed. There are many better products out there at a lower price.
              I used this for 1-1/4" iron heat pipes. The memory in it had no ability to keep it closed onto the pipe. The glue doesn't hold it shut. It needs to be taped every 6"-8" just to keep it on the pipe. The result is poor insulation with a crummy looking final job. If you need a good looking final product you'll probably need to replace this stuff after you install it.
              I recommend that you get a better pipe wrap.

                                      Replaced the original insulation that was only 3 years old. The quality of this product was markedly better than the original. Shipping was lightning fast, and I received the product WAY faster than anticipated.

Will know later if it does keep the hot water hot going from the water stove to the heat exchanger in my forced air duck work. No problems with the product and got great service with the people from Pex supply.

                                                                I have a 1 1/2 sump pump line that extends 18 inches past the exterior wall. I live in Wisconsin and was wondering if this will help the 18 inch of pipe sticking out the exterior wall from freezing. The water from the sump pump is then piped underground to a drainage ditch. The underground pipe never seems to freeze, but that 18 inches of pipe seems to. Can you help??

                                                                  If allowance were made for expansion, the foam insul could be used on stick (non-flexible)PEX, but that's typically only 1-inch and larger pipe.

                                                                  A:

                                                                  The tubing for the A/C units are not standard sizes. The tubing is usually dependent on the manufacturer, model and size of your A/C unit. This is the largest line insulation we sell so it will most likely work in your application. It may be a little loose on the lines but you would be able to zip tie the insulation down to the tubing.
