2-1/2" Pipe Insulation Trap

Owens Corning 147383 is a fiberglass pipe insulation tube designed for 2-1/2 inch piping systems. It features a 1-1/2 inch wall thickness and an overall length of 3 feet. The tan colored tube carries an R-value of 11.8 for thermal resistance.

For plumbing thermal protection

This insulation suits installers needing to wrap 2-1/2 inch pipes against heat loss or condensation. The slit design with adhesive flap allows quick fitting around existing runs. It is not for buyers needing flat sheet insulation or products sized for different pipe diameters.

Slit adhesive flap simplifies install

The factory slit with adhesive and flap closure removes the need for separate tape or fasteners during application. ASJ facing provides a clean vapor retarder surface suitable for plenum-rated environments. Flame spread index of 25 and smoke developed index of 50 meet common building code requirements.

Questions about this item

Does the 2-29/32 in inside diameter fit my 2-1/2 in pipe?

Yes, the 2-29/32 in inside diameter matches the listed 2-1/2 in pipe size for a direct slip-on fit.

Can I run this insulation next to existing metal pipe rated for lower temperatures?

The insulation handles up to 1,000 Degrees F, so it will not degrade when adjacent to cooler-rated metal pipe.

How do I confirm the slit with adhesive and flap is sealed correctly after installation?

Press the flap firmly along the full 3 ft length; the adhesive bonds on contact and the facing stays closed without gaps.
