1" x 3 ft Pipe Insulation Trap

The Owens Corning 199744 is a fiberglass pipe insulation tube designed for plumbing applications. It fits 1-inch pipe size and 1 3/8-inch copper tube size. The slit design with adhesive and flap allows for straightforward installation around existing piping. This product suits contractors and DIY users insulating standard hot or cold water lines.

R-7 thermal resistance up to 1,000 Degrees F

The insulation provides an R-value of 7 with a 1-inch wall thickness. It operates continuously from 0 Degrees F to 1,000 Degrees F. The ASJ facing delivers a flame spread index of 25 and a smoke developed index of 50. It is plenum rated for use in air handling spaces. Performance limits are defined by these temperature and fire ratings.

ASJ facing with adhesive flap closure

The all-service jacket facing acts as a vapor retarder and protective outer layer. The integrated adhesive flap seals the longitudinal slit without requiring separate tape. This feature simplifies the installation process and helps maintain the insulation's thermal integrity. The facing also contributes to the plenum rating and low smoke characteristics.

Questions about this item

Will the 1" wall thickness and 1 25/64" inside diameter fit over my existing 1" copper pipe without removing it?

Yes, the tube is slit with adhesive and flap so it wraps around installed pipe; the 1 25/64" inside diameter matches 1 3/8" copper tube size for a snug fit.

How can I verify the insulation is performing to its R-7 rating after I install it?

Confirm the ASJ facing is intact, the adhesive flap is sealed along the full 3 ft length, and the surface temperature stays well below the 1,000 °F maximum during system operation.

Does the package include the 199744 tube only, or are extra tapes or fasteners supplied?

The box contains the 3 ft slit tube with self-sealing adhesive flap; no additional tape or fasteners are included.
