Pipe Insulation Trap 1/2" x 3 ft

This Owens Corning 199774 fiberglass tube fits 1/2 inch copper pipe with a 7/8 inch inside diameter. The 1-1/2 inch wall thickness delivers an R-value of 13.2 for thermal control on hot or cold lines. It is designed for residential or commercial plumbing systems requiring consistent temperature maintenance.

Verify pipe size and temperature range

Confirm the copper tube measures 7/8 inch outside diameter before ordering. The insulation operates between 0 and 1,000 degrees Fahrenheit. Check that the slit-with-adhesive-and-flap closure suits the installation layout and that local codes accept a flame spread index of 25 and smoke developed index of 50.

Fiberglass construction with ASJ facing

The tan fiberglass core is wrapped in ASJ facing for durability and a clean appearance. The self-sealing adhesive flap simplifies installation without extra tape. Plenum-rated materials meet fire-safety requirements for air-handling spaces, and the rigid tube form holds its shape on straight runs.
