SD-28A Shouldered Toggle Coupling Download PDF



The Shurjoint Model SD-28A coupling is designed to connect shouldered-end pipe with Type A rings for services where frequent assembly and disassembly is desired or required.  The housing segments are hinged with a lever handle for easy installation.  The use of a split pin prevents accidental opening of the couplings.  The housing segments are made of ductile iron to ASTM A536 Gr. 65-45-12 and or A395 Gr. 65-45-15 and are normally supplied in hot-dip galvanized.  The standard rubber gasket is Grade T Nitrile.

*Working pressure is based on standard wall carbon steel pipe.
