Description for K-Flex 6RXL038058

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.

Features and Benefits:

  • Faster install
  • Ideal for straight runs
  • Moisture vapor resistance
  • Seam seal pressure sensitive adhesive (PSA) for quick and easy installation with no mess
  • Withstands temperature ranges of -70°F to 200°F (-57°C to 93°C)
  • Mold and mildew resistant

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.

pain to install

Comments about 1/2" Pipe (O.D.) x 3/8" Wall Insul-Lock Pipe Insulation, 6':

I'm sure the R-value is good but the protective cover of the double sided tape will come off as you are working with it and then the insulation sticks to the side of the pipe. Sometimes when you do get ready to peel the backer the whole piece of tape comes off instead. It's also very floppy so it twists up easily.

We have an old house with steam heat. Needed to cover a couple of pipes but the size that was generally available was too small. This is the only source we could find that had what we needed. The only options others offered was the insulation type and we wanted to use the foam tube type. The product arrived timely and we are pleased with it.

Used the product to insulate pipe in ground which was covered by another pipe. Some of the insulation was damaged in that the adhesive tape was not in the proper place.

It was stuck to the outside of the insulation.

Bad product

By Jim

from Illinois

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.

  • 1/2" Pipe (O.D.) x 3/8" Wall Insul-Lock Pipe Insulation, 6'

    Q:

    Says 1/2 pipe O.D. in title, but the Application: say 3/8" Pipe.
    So is this for 3/8 or 1/2 copper pipe?
    Asked on 9/22/2015 by M

    1 answer

    • CUSTOMER CARE

      A:

      So this insulation is for use on pipe that has 1/2" OD (or 3/8" nominal ID) sizing. So that is why both sizes are listed, to clarify which type of pipe it would be compatible with.

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

    Q:

    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??
    Asked on 4/1/2014 by HD

    1 answer

    • CUSTOMER CARE

      A:

      Yes, adding insulation to the exposed 18" of pipe will help reduce the risk of freezing. This product has moderate UV resistance and can be used in outdoor applications (except roofs).

    Q:

    I read and my supplier says that the pre-glue strip foam pipe insulation cannot be used on PEX. What makes some insulation PEX ready and some not? What makes the Insul-Lock PEX compatible?
    Asked on 7/15/2013 by James

    1 answer

    • VERIFIED BUYER

      A:

      There's no thermal reason that it won't work, and the diameters are about the same, but there's no effective way to install/hang/support it and have it look decent.  As well, PEX expands and contracts which, depending on how the insulation is installed and supported, may cause the glue seals the separate over time.
      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:

      Travis,
      I'm assuming you mean 1-1/4 "black iron" pipe instead of "cast iron". In
      which case a 1-1/4" black iron pipe has an outside diameter of 1.66",
      therefore, this choice of insulation will not work.

    Q:

    I am puting in a hot watter circulaing reiculating system for my new tankless system using 3/4 pex . I want to insulate the hot water piping . all is installed in basemnt .Don't want to loose heat in circulting lines.What schould I use for pipe insulation?
    Asked on 5/13/2012 by Gary from Cleveland,ohio

    2 answers

    • VERIFIED BUYER

      A:

      First, remember pex needs to be supported. Plan the support system while
      planning the insulation of the line.
      Doubling the R-value does not mean you cut the heat loss in half. However
      added insulation will always reduce the loss. The key is that there is a
      point of diminishing returns.
      If you can afford it and want to reduce as much heat loss as possible -
      double up on the insulation. The key is that corners, bends, connectors
      should also be insulated and sealed. I my recirc lines I can feel and
      measure some heat loss through the insulation even though I used a ½ wall
      insulation. I will probably go back and add a second thicker (cheaper)
      layer of pipe insulation on top of what I had previously done.
      You need to meet the minimal codes in your area. After that it comes down
      to how much you are willing to spend and if you are expecting a fast or
      slow return on your investment.

      This insulation can be used with PEX. PEX has the same outside diameter as copper and CPVC. Outside diameter will always be 1/8" larger than the listed size of the tubing.
