 Product Description

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 fiberglass pipe insulation 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!

Click on the link below to view the PVC Sizing Charts to see which size PVC Fitting you need.  The PVC Fitting size is based on both the size of the pipe and the thickness of the insulation being used.

  1. Easy install, professional look

    Posted by Dave K. on 25th Apr 2019

    I've never insulated pipe before and I had no trouble getting these to fit and look professional. I would recommend watching the installation videos if you've never done this before as they do have some good tips that will help you get things to fit tight.

    There is something very satisfying about getting these fittings to go on as tight and cleanly as they do. They are easy to cut and modify if you have close fittings that impede with the cover.

  2. One was good

    Posted by Jeremy from TM on 22nd Mar 2019

    I got a 5" and a 6". The 5" one was inside out - hard to explain. The inside corner of the elbow, where the seam is: those edges were curved the wrong way. Really hard to install. The 6" one was perfectly fine, great product. I got these instead of the Victaulic ones because they were cheaper and I thought they looked nicer. These + Victaulic coupling covers are a pretty good set. Have to notch them where the coupling bolts are, however.

    *Jeremy, sorry to hear one of the PVC covers were unflipped. Anyone reading this, we do have a video that shows how to curl the fitting back if they uncurled. ~BIP

  3. Very Satisfied

    Easy to put together and everything fits perfectly. Holds heat very well. Very happy with this purchase.

  4. They can handle the heat!

    Posted by Adam F. on 1st Nov 2018

    I’ve used these in a few steam installations. They come with plenty of insulation, and seem to hold up to the heat very well. Don’t forget to order your tape and tacks!

  5. Easy to use

    Easy to use , fast installation!!

  6. Good fit

    Posted by Unknown on 14th Jun 2018

    Insulation is easy and it looks good

  7. PVC cover

    Posted by Unknown on 28th Jan 2018

    Easy to install. Fit very well. Came with alot of insulation. Recommend buying the special pins to secure the cover.

  8. Easy to install, with one caveate

    Posted by Christine H. on 25th Jan 2018

    These went up fairly easily except where I had two or more joints overlapping. They work Perfect when each side is over the pipe insulation. Unfortunately I had several intersections with multiple joints side by side with no pipe length in between. I used a bunch of extra tape at these points. If you have multiple joints side by side call the reps and ask for assistance I deeming how to handle. I will be purchasing more products from here again in the near future.

    *Christine, the key to insulating back to back fittings is to cut a sliver of pipe insulation and put that on the small section of piping between the two fittings. This way the PVC covers have something to sit on. You may also have to trim the fitting covers with a scissor to fit properly. ~ BIP

  9. Great product

    Posted by Unknown on 21st Sep 2017

    Simply a great product for it's purpose

  10. Works OK for solar applications

    Posted by Unknown on 9th Jul 2017

    These PVC elbows get the job done, however, they necessarily come with rock wool insulation--which is not compatible with our solar work. We use K-Flex elastomeric foam insulation and end up throwing out the rock wool: what a waste.
    Also like most PVC shells they are fragile in cold weather and tend to split when tacks are inserted. Keep them warm, pre-punch holes or wait for warmer weather.

    *We do provide a fiberglass insert for each fitting, if you do not need inserts let us know and we can exclude them. ~BIP
