Housing

The housing segments not only provide significant strength to the joint but they also compress and protect the gasket from exposure. Shurjoint coupling housings and components are cast in a variety of materials as shown below.

Ductile Iron:
Standard coupling housings and fittings are made of ductile iron conforming to ASTM A536 Gr. 65-45-12. The properties of Grade 65-45-12 ductile iron are as follows; 65,000 psi (448 MPa) tensile strength; 45,000 psi (310 MPa) yield strength and 12% elongation. As an option we also offer ductile iron made to ASTM A395 Gr. 60-40-18, for applications where required or where boiler codes may apply.

  

Stainless Steel:
We offer a variety of stainless steel casting materials depending on your intended application. Standard coupling housing and fitting materials include CF8 (304), CF8M (316) or CF3M (316L) per ASTM A743. Optional materials include 2205 Dplex, 2507 Super Duplex and ASTM CK-3MCuN (UNS J93245), equivalent to 254SMO*. (* 254SMO is a registered trademark of Avesta Polarit AQB.)

  

Bronze:
Standard fittings are made of lead-free copper alloy per ASTM B584. The Shurjoint copper alloy is UL classified in accordance with ANSI/NSF 61 for cold +86℉ (+30℃) and hot +180℉ (+82℃) potable water use.
