Rigid PVC conduit coupling is a non-metallic fitting made of polyvinyl chloride (PVC) used to join two plain-end sections of rigid PVC conduit.
Featuring a cylindrical shape with two socket openings to accommodate the ends of rigid PVC conduit, the coupling ensures a watertight, corrosion-resistant connection, ideal for protecting electrical wiring in underground, outdoor, or wet environments.
