Standard Specification for Mechanical Couplings Using Thermoplastic Elastomeric (TPE) Gaskets for Joining Drain, Waste, and Vent (DWV), Sewer, Sanitary, and Storm Plumbing Systems for Above and Below Ground Use


This specification covers the performance of shielded transition couplings using flexible PVC gaskets to join dissimilar DWV pipe and fittings above and below ground. The gaskets shall be permitted to be spliced or molded. The elastomeric gasket shall be free from imperfections and porosity that affects its use and serviceability. Clamps assembly screws or bolts shall not have screw-driver slots. Each coupling shall undergo deflection test, shear test, and unrestrained hydrostatic joint test.


1.1 This specification describes the properties of devices or assemblies suitable for use as mechanical couplings using thermoplastic elastomeric (TPE) gaskets, hereinafter referred to as couplings, for joining drain, waste, and vent (DWV) sewer, sanitary, and storm plumbing systems for above and below ground use.

1.2 The pipe to be joined shall be of similar or dissimilar materials or size, or both.

1.3 The values stated in inch-pound units shall be regarded as standard. The values given in parentheses are for information only.

1.4 The ASTM standards referenced herein shall be considered mandatory.
