4" Schedule 40 Deep Socket Coupling Slip x Slip (482-040 / 479-040)

Deep socket couplings allow the user to connect two pieces of piping in a straight line. They are called "deep socket" because the piping sits deep inside the fitting, making it easier to create an air-tight seal than with a traditional coupling. This 4" Schedule 40 Nested Coupling has double slip ends. This means that it is compatible with 4" schedule 40 PVC piping on both ends.This fitting is made from professional-grade schedule 40 PVC, giving it impressive structural integrity and high pressure tolerance for its weight. Schedule 40 PVC is not rated for use with hot water. PVC cement is necessary for a tight seal on slip connections.
