Insulated 90° Elbow Jacket

The Unitherm IE0890 is a silicone-coated fiberglass cloth jacket designed to wrap a 90-degree elbow fitting in industrial piping systems. It uses fiberglass and mineral wool insulation rated for a maximum ambient temperature of 900 Degrees F and meets OSHA standards.

Suits maintenance crews needing quick fitting

Teams that require fast installation on elbows with circumferences between 19 in and 25 in will benefit from the quick-release fabric flap and wiretwist fastening system. It is not suited for straight-pipe runs, smaller or larger diameter elbows, or applications exceeding the stated temperature limit.

Quick-release flap and wiretwists speed up fitting

The fastening system lets technicians open and reseal the jacket without tools, reducing downtime during inspections or repairs. The R-value of .48 provides a measurable thermal barrier for the covered elbow section.

Questions about this item

What pipe circumference range does the 890 elbow jacket cover?

The jacket fits pipes from 19 inches minimum circumference up to 25 inches maximum circumference.

Will the fiberglass insulation withstand the 900-degree steam header I'm keeping?

Yes, the silicone-coated fiberglass cloth and mineral wool insulation are rated for a maximum ambient temperature of 900 degrees F.

How can I confirm the quick-release flaps and wiretwists are holding the jacket securely after installation?

Check that the fabric flaps lie flat with no gaps and the wiretwists are tight enough to prevent movement when the pipe vibrates.
