Industrial REJ20 PVC Conduit Fittings and Boxes

ROYAL REJ20 O-Ring Expansion Joint is a 1-inch expansion fitting designed to bridge sections of PVC rigid conduit, specifically to absorb thermal expansion and contraction along long conduit runs and prevent stress at joints and fixtures. This grey unit uses an elastomeric O-ring seal to maintain a tight connection between conduit segments, while remaining flexible enough to accommodate slight misalignments and movement without compromising electrical integrity. Certified for CSA and UL approvals and sold individually, the REJ20 is part of Royal Pipe Systems' PVC fittings line and is compatible with standard PVC rigid conduit systems in commercial and industrial installations. Typical applications include long straight runs in warehouses, manufacturing floors, data centers, and outdoor electrical installations where PVC conduit is preferred, helping to reduce wear on fittings and boxes and extend the life of the conduit network. The compact, non-metallic design minimizes corrosion concerns and is compatible with common PVC conduit line configurations, making REJ20 a straightforward option when thermal management is a priority.
