They make PVC formed covers for elbows & tees. They come with a fiberglass "diaper" you wrap around the fitting, then you seal the cover on with tape. The come sized for the O.D. of your insulation; a good source will have a sizing chart available.

    Pipe Joint Insulation


    I am a homeowner with steam boiler and the pipes in the basement are not insulated. I am planning on using fiberglass pipe insulation to cover the pipes. Would like to see what you recommend for the elbow joints. A few people have suggested a brush on acrylic or cement that could be used on the elbow joints and also be used to seal the fiberglass. I am a little confused about this and would appreciate any suggestions.


  • or you can use

    Cold water paste with cheese clothes to form around fittings, etc
