Closed-cell pipe insulation with self-sealing adhesive seams for refrigerant, plumbing and chilled-water lines

  • Prevents heat flow with closed-cell insulation design
  • Stops condensation when installed correctly on piping systems
  • Self-sealing adhesive seams speed up installation time
  • UV-resistant elastomeric blend handles moderate sun exposure
  • Model 48118 suits refrigerant lines and chilled water systems

Pipe insulation for refrigerant

This closed-cell elastomeric insulation is designed to limit heat transfer and stop condensation on refrigerant lines, cold water plumbing, roof drains and chilled water systems. It arrives pre-slit with factory-applied bonding adhesive on both seam surfaces and release liners for straightforward installation. The material resists moderate UV exposure without extra coating. Professional installers and facility maintenance teams will find it suited to commercial and residential mechanical systems.

Check line diameter and UV exposure before ordering

Verify that the 1-1/8 inch nominal inside diameter matches the pipe or tubing you are insulating. Confirm the 1/2 inch wall thickness satisfies your thermal and condensation-control requirements. For severe rooftop UV exposure or where optimum performance is required, plan to apply 374 Protective Coating or an approved jacketing or cladding system. Orders below $75 do not qualify for free manufacturer-direct shipping.

UV-resistant elastomeric blend

The insulation uses a closed-cell elastomeric blend formulated to withstand moderate sunlight without degradation. Its self-sealing seam relies on a specially formulated adhesive that bonds when the release liners are removed, creating a continuous vapour barrier. The six-foot length reduces the number of joints on long runs. No additional protective coating is needed for typical indoor or shaded outdoor installations.

Questions about this item

What comes in the box and what must I buy separately?

The product arrives as a six-foot length of pre-slit Insul-Lock Self Seal pipe insulation with factory-applied adhesive on both seam surfaces and built-in release liners; for severe UV exposure you will need to purchase 374 Protective Coating or approved jacketing separately.

Which version or capacity should I choose for my pipe?

Select the 48118 model when you need a six-foot stick sized for 1-1/8 inch nominal inside diameter with a half-inch wall thickness; other lengths, diameters or wall sizes are different part numbers.

What does the six-foot length mean once the insulation is installed on a real pipe?

Each stick covers six linear feet of 1-1/8 inch nominal pipe, the pre-slit seam and self-seal adhesive let you press the edges together without tape, and the half-inch wall provides the stated thermal barrier for refrigerant lines, cold water plumbing, roof drains or chilled water systems.
