They do make molded plactic covers that you rivet togeather for joints, but they are often hard to find. Underneath these molded plastic covers I usually find stuffed fiberglass.

As far as where to buy. I'll do some research and see what I can come up with. I usually sub out mt sateam insulation jobs to an insulation contractor.

    I am insulating the steam pipes in my basement and purchased enough 3' x 1" sections of fiberglass insulation to do the job. The sections won't fit over pipe joints and I don't think it's good to leave the fiberglass exposed on the sides of the pieces coming up to the joints. What is the best way to complete the pipe insulation over these larger areas and elbows?

    Thanks!

    INSULATION

    An inexpensive way to insulate pipe fittings is to purchase a bag of "stick-tight" It's mixed with water then place the mixture over the fittings before you put on the straight lengths. Use your hands to form the insulation around the fittings and smooth it out with a butter knife. Wait for the joints to dry before you insulate the piping. This way the water won't stain the covering. Much less costly than the PVC fittings. For the T fittings,valves and unions you can purchase a larger diameter covering, and cut out for the branches, collars or handels.

    Thanks Norm. I was thinking that there must be some sort of fiberglass "wrap" that I could put around them? I look forward to hearing what you find.

    Thanks for the response frankiewrench. I was thinking about buying some larger insulation and then cutting it to fit. Now that you suggested it too, I might take that route.
