FAQ: What kinds of joints are available, and how many will I need?
The Phenolic Joining System includes the Adhesive Joint, which is the straight socket joint combined with the appropriate adhesive. The adhesive is applied to the spigot end of the conduit. Various straight socket expansion joints are also available; expansion fittings should be provided to compensate for thermal expansion and contraction. You can find more information on the Phenolic Joining System in our Champion Flame Shield® catalog.
