Designed to provide a durable mechanical joint for grooved end stainless steel piping systems,
Style 475 stainless steel couplings are available in Type 316 (CF8M). See chart on page 2
for pressure ratings. The Style 475 comes standard with WRAS- certified, Grade “EW” EPDM
gasket material with approved microbiological resistance.
Stainless steel track bolts, which provide single-wrench tightening, are provided as standard.
The Victaulic system accommodates expansion/contraction/deflection and permits designers
to take advantage of these characteristics. Elimination or reduction of special vibration
expansion loops and settlement allowance are among the options. Request
26.01, 26.02 and 26.04 for additional details.
Unique design features of the Style 475 coupling permit assembly by removing one nut/bolt
and scissoring housing over gasket. This reduces the number of components to handle during
assembly, which speeds and eases installation.
Type 316 stainless steel, conforming to ASTM-A351, A743, and A744 Grade CF8M.
