PVC Insulated Elbow Cover

The Johns Manville 32810 is a PVC insulated fitting cover designed for a 90 degree elbow with a maximum outside diameter of 5 5/8 inches. It includes a fiberglass insulation insert and a white PVC jacket. The cover meets multiple ASTM standards for material performance and fire safety. It is intended for indoor and outdoor plumbing installations.

Suited For Standard Elbow Insulation

This cover suits installers insulating a standard 90 degree elbow within the specified diameter range using tacks or tape. It is not for buyers needing insulation for straight pipe runs, tees, or other fitting geometries. It also does not suit projects requiring a different jacket material or operating temperature range beyond the listed limits.

Sustained Temperature Performance

The product operates continuously between -32 degrees F and 150 degrees F. The fiberglass insert and PVC jacket maintain thermal resistance and structural integrity across this range during sustained exposure. Compliance with ASTM E84 and E136 indicates verified fire performance under prolonged heating conditions rather than short-term testing only.

Questions about this item

What tacks or tape are needed to install the PVC jacket cover?

The cover uses tacks or tape for installation; choose corrosion-resistant tacks or UL-listed PVC tape rated for the -32 °F to 150 °F range.

Will the 90-degree elbow cover fit over existing pipe insulation?

It fits a maximum outside diameter of 5 5/8 in, so measure the insulated pipe OD first; if it exceeds that size the cover will not close.

How can I confirm the fiberglass insert is seated correctly after fitting the cover?

After taping the jacket, press along the elbow — the insert should feel uniformly firm with no gaps, and the white PVC surface should lie smooth without wrinkles.
