Product Identity

The Owens Corning 147364 is a 3-foot fiberglass pipe insulation tube designed for 4-inch pipes. It features a 2-inch wall thickness and a slit design with adhesive flap for straightforward installation on hot or cold plumbing lines.

Ideal Installers

This insulation suits contractors and facility managers needing plenum-rated wrap with a high R-value of 12.1 for thermal efficiency. It is not for installers who require a different inside diameter or a product rated for temperatures above 1,000 degrees Fahrenheit.

Included Benefits

The ASJ facing provides a durable vapor retarder and a finished appearance without separate jacketing. The pre-applied adhesive flap eliminates the need for separate tape or bands, reducing labor time on the job site.

Questions about this item

What size pipe do I need to already have for this 4 in insulation trap to fit?

It is made for a 4 in pipe with an inside diameter of 4 17/32 in.

Will the adhesive flap on this fiberglass tube stick properly to older metal pipe?

The slit design with adhesive and flap is intended to seal around the pipe once pressed in place.

How can I confirm the R-value of 12.1 is performing after installation?

Measure the surface temperature; it should stay close to ambient when the pipe runs at its operating temperature.
