Flexible Coupling

Style 475

 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

accessories,

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.
