These rigid couplings have PVC sleeves on both ends to help seal out moisture and prevent corrosion to protect the conductors inside. They are often used in industrial environments where liquids are present. They position onto the ends of two lengths of PVC conduit and are solvent-welded in place for a secure, liquid-tight connection.

These split couplings join two pieces of PVC conduit where the conduit can't be turned because of limited clearance between runs, a wall, or other obstruction. They slide over the two ends of the conduit to butt them together and tighten in place with a bolt and nut.

These reducing couplings are used to join two pieces of PVC conduit that are different sizes. They position onto the ends of the conduit and are solvent-welded in place to join them together.
