PVC 90° Degree Steam Pipe Insulation Elbow Covers are used to insulate 90° degree pipe elbow fittings. Each PVC pipe cover comes with a sized fiberglass insert which is made from die-cut fiberglass blanket. The fiberglass insert is wrapped around the elbow ensuring that all of the pipe is covered by insulation. The PVC Pipe Elbow Cover is a pre-molded plastic one-piece cover that fits around both ends of the fiberglass pipe insulation and overlaps on the inside seam. The inside seam of the steam pipe insulation elbow can be closed one of three ways:

1.) Use serrated stainless steel King Tacks which are pressed through the overlapping pieces of the elbow cover and will hold them securely. (Steam, Hot Water, etc)
2.) Use PVC Vinyl Z-Tape to seal the elbow cover to the fiberglass pipe insulation. (Cold Water, Chilled Liquid, etc)
3.) Use Proto One PVC Adhesive to glue the seams of the PVC pipe cover. (Exterior Piping, USDA, Washdown Area, etc)
*Tacks, Vinyl Tape, and Adhesive are sold separately.

*PVC 90° Elbow Covers are available in 13 high gloss colors!

    I used this to cover a 90m degree elbow in a heating/cooling duct which was on the ceiling of an un-heated tuck-under garage. It worked very end in conjunction with fiberglass insulating sleeves placed over the straight sections.

    Works great

    Great, easy way to insulate elbows. One thing to keep in mind, if you have hard to reach areas or elbows are in a tight corner/area, then it may be difficult to get the tape around the cover and you would be better off using the taps. I opted for the tape and had a hard time in some tight spaces, wish I had opted for the taps instead. In the end was able to get it sealed and looks great though.

    The PVC 90 degree elbow cover makes during them so simple with how the insulation is formed for you that comes with this kit and how the cover fits so neatly over the elbow. Makes the job look so nice and the ease of finishing them tough spots lots easier

    Certain sizes dont arrive looking like elbows

    Posted by T H. on 3rd Oct 2020

    putting these sizes together like elbows NEEDS about 5 arms/hands - all elbows should snap together

    *T~ Some of the larger fitting covers (you ordered #17) are shipped unflipped from the manufacturers to protect them during shipping. These fittings will resemble what we call a Captain Crunch Hat or a knee cap. These can be easily flipped:
