Deep slip couplings are slip couplings that are for use in special situations. They are simply "slip" couplings that both ends of the pipe glue into, but are longer overall, allowing the pipe more area for cement contact. Deep socket couplings are perfect for higher pressure situations and also work well with flexible PVC pipe, providing an extra layer of protection against pipe separation. Both pipe ends are glued into the coupling, forming a joint.
