Owens Corning 722605 pipe insulation 3 ft

Owens Corning 722605 is a 3 ft length of fiberglass pipe insulation with a 1/2 in wall thickness and an inside diameter of 1 11/16 in. It features ASJ facing, a slit with adhesive flap for installation, and an R-value of 2.7. The product is plenum rated with a flame spread index of 25 and smoke developed index of 50. Suitable for copper tube size 1 5/8 in and pipe size 1 1/4 in.

Best for standard hot and cold pipe runs

This insulation suits installers covering 1 1/4 in pipe or 1 5/8 in copper tube in commercial or residential systems operating between 0 and 1000 degrees F. The adhesive flap speeds up fitting on straight runs. It is not for buyers needing foam-based insulation, different wall thicknesses, or non-plenum-rated materials for unrated spaces.

1/2 in wall thickness and 1 11/16 in inside diameter

The critical specification is the 1/2 in wall thickness combined with the 1 11/16 in inside diameter, which determines fit on 1 1/4 in iron pipe or 1 5/8 in copper tube. Verify the pipe outside diameter matches this inside diameter before purchase. The R-value of 2.7 and temperature range of 0 to 1000 degrees F define the thermal performance envelope.

Questions about this item

How do I install the slit tube with adhesive and flap, and what step do people miss?

Wrap the tube around the 1 11/16 in pipe, peel the adhesive backing, press the flap firmly to seal the seam, and secure the butt joints with tape; the step often missed is sealing the joints, which lets heat escape.

What maintenance or replacement will this fiberglass tube need over time?

Inspect the ASJ facing annually for tears or moisture damage; replace any section where the facing is compromised or the fiberglass is wet, as damaged facing reduces the R 2.7 thermal performance.

At what temperature limit does this insulation reach its maximum rating during sustained use?

The maximum operating temperature is 1,000 degrees F; sustained exposure above this degrades the fiberglass and ASJ facing, so keep pipe temperatures at or below that limit.
