Squeeze out a little more insulation value

Why would any residentail heating contractor be interested in 1 5/8" ID insulation? I use this insulation to insulate pipe unions, ball valves and other hard to insulate plumbing. Typically, most of the piping can be insulated with standard pipe insulation. Augmenting that insulation with insaulation that can warp over the typical insulation allows you to finsih the job.

OK product, poor packaging

I was very disappointed when I received my shipment of pipe insulation from Supply House.com. Because I didn't order a full box quantity the insulation came packaged in a large square box. This caused the adhesive to transfer strips to loose their protective covering and the adhesive migrated onto the mashed pieces of insulation that were in the box. This box contained both 7/8 and 1 1/8 in. insulation and the pieces were much more difficult to use after they had become misshaped by the shipping process. 1 1/8 in. insulation that was shipped in the correct size container showed none of these problems

Great Product and a Smooth Transaction!

I bought this pipe insulation to cover a 3/4" Pex water supply from source to an RV. I haven't installed it yet, but it looks to be perfect for it's intended purpose. It was well packaged, and the shipping was fast.

High quality material, super fast delivery

It's pretty straightforward in that the one I selected is for 7/8" tubing. This product wraps around the pipe, and the split is joined (closed) with pre-applied adhesive. then a second secured flap (with adhesive) covers the seem. It looks great and seems to seal well.

The closest option would most likely be the piping listed for 1" applications.

Q: I have a 10 foot pipe that is 3 inches in diameter. Will this insulation work?

Asked by Taylor 10 years ago

Yes, this would be compatible with 3" diameter piping. It is a 6ft long piece so two pieces would be needed for 10 ft. long run.

Q: Will this insulation work on HVAC line set

Asked by Mark 10 years ago

Verified Author and ReplyVerified Reply- SupplyHouse Staff

This closed cell insulation is designed to retard heat flow and prevent condensation when properly installed. This product is recommended for applications ranging from -70°F to 200°F (-57°C to 93°C) for both new and existing applications, so it would not be ideal for HVAC lines.

Q: How strong is the glue? If at some time in the future I need to remove this can it be removed with out tearing and reused.

Asked by Marcy 12 years ago

The glue is extremely sticky and there is no way to reuse it. In fact, you have to make sure the piece is in place before you take off the plastic backer. Otherwise the glue sticks to everything including the pipe. To make sure the glue continues to stick, I would recommend some cable ties in the areas that are likely to come apart, like 90 degree turns. good luck!

Adhesive strips will tear when separated, Though the black 620 adhesive is AMAZING good. cut it ope with scissors for a clean cut (though glue will work on tears too), coat both edges to be mated with glue, let dry 5 or 10 minutes, then carefully place the ends together. This 620 glue is all I use for hot and chilled pipes, no matter what brand of insulation I use. K-Flex Black 620 by far out performs any other brand of glue. works for corners, butt splices, and even adhering sheets to flat plate heat exchangers.

my experience was that the glue strip tended to de-laminate from the foam when I pulled it apart, although not entirely. you could maybe only reseal it once but I would have glue on hand - not sure which kind would be best for the application. good luck!

Q: At what temperature will a domestic water line wrapped in this product freeze

Asked by Bob 13 years ago

32 Degrees Fahrenheit.

If the water in the line is not moving than eventually (a few days) the line will freeze. It does not lower the freezing point of the line but only insulates it and the cold will eventually penetrate the line if the liquid is not moving.
