Champion Fiberglass Elbows and Xpress Elbows

Can I use Champion Fiberglass with other conduit materials?

Fiberglass elbows are frequently provided with PVC couplings to transition to underground PVC conduits. Also, PVC or fiberglass male/female adapters are used to transition to GRC and PVC-coated rigid steel conduits. We only recommend using fiberglass couplings for fiberglass-to-fiberglass connections.
