Pipe Insulation for 2 1/8 in Copper Tubing

This three-foot fiberglass tube fits copper pipe with a 2 5/32 inch inside diameter and provides a one-inch wall thickness. The slit design includes an adhesive flap for straightforward installation on residential or commercial plumbing systems. Its tan ASJ facing delivers a clean appearance in exposed locations.

Sustained Temperature Performance

Rated for continuous operation from 0 to 1,000 degrees Fahrenheit, the insulation maintains its R-value of 5.4 across the full range without degradation. The fiberglass core resists settling or compression that would reduce thermal resistance over long heating seasons. Plenum-rated construction meets fire-safety requirements for air-handling spaces.

Fire-Safety and Application Limits

The product carries a flame spread index of 25 and a smoke developed index of 50, qualifying it for plenum installations where building codes restrict surface-burning characteristics. It is not intended for outdoor direct-burial or unprotected exterior runs where UV exposure or mechanical damage could compromise the facing. Buyers needing higher R-values per inch or a vapor-barrier jacket for below-ambient piping should consider alternative materials.

Questions about this item

Does the 1-inch wall insulation get too hot to touch when the pipe runs at 1,000 degrees Fahrenheit?

The facing material is rated for up to 1,000 degrees Fahrenheit, but the outer surface temperature depends on the pipe temperature and ambient conditions; it is not guaranteed to stay cool.

What pipe size do I need so this 2 5/32-inch inside diameter fits correctly?

It is made for 2 1/8-inch copper tube size, which matches the 2 5/32-inch inside diameter.

Will the flame-spread index of 25 and smoke-developed index of 50 meet code if I run it through a plenum space?

Yes, the product is plenum rated and carries a flame-spread index of 25 and smoke-developed index of 50.
