Verified Reply- SupplyHouse StaffHi Jim, thanks for writing in. 3/4" PEX tubing has an OD of 7/8", so this pipe insulation will work for it.
Q: What is the procedure to join the ends of k-flex insulation (7/8" ID--1/2" wall thickness)?
Asked by Tom 10 years ago
Add your answer
Verified Reply- SupplyHouse StaffA suitable adhesive such as SKU : 800-620-PTB can be used to connect ends of insulation.
Q: Is this produce UV rated; for external HVAC pipes that will be exposed to sunshine 365 days/year and will not deteriorate because of this/the elements?
Asked by LJ 10 years ago
Add your answer
Verified Reply- SupplyHouse StaffThis insulation is UV resistant and is rated for moderate UV exposure only. For severe exposure, 374 protective coating or approved jacket must be used.
Q: What size insul-lock pipe insulation is recommended for 5/8" pipe with 3/4" O.D.? I don't see one list to fit this size pipe. Thank you
Asked by John 10 years ago
Add your answer
Verified Reply- SupplyHouse StaffThe closest option would most likely be the piping listed for 1" applications.
Q: What is the inside diameter of the cavity? What size pipe insulation do you recommend to insulate a 2 inch outside diameter pipe?
Asked by Joe 10 years ago
Add your answer
Verified Reply- SupplyHouse StaffThe inside diameter is 4 1/8" on the inside of the insulation tube. If the 2" outside diameter is copper use sku 6RXL048218. If it is iron pipe size or PVC use sku 6RXL048238.
Q: I have a 10 foot pipe that is 3 inches in diameter. Will this insulation work?
Asked by Taylor 11 years ago
Add your answer
Verified Reply- SupplyHouse StaffYes, 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 11 years ago
Add your answer
Verified Reply- SupplyHouse StaffThis 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 13 years ago
Add your answer
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
Add your answer
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.
