Slip-On Flange, 304/304L Stainless Steel, 3/4 in Pipe Size, Raised Face, Class 150, 4 Bolt Holes

The ZORO SELECT - 4381000410 is a stainless steel pipe flange designed for boltable pipe connections. It features a bolt circle diameter of 2 3/4 inches, four bolt holes of 5/8 inches each, and a flange outside diameter of 3 7/8 inches. This allows for the creation of pressure-tight joints with gasketing and bolting. Made of 304/304L stainless steel and classified as Class 150, it is suitable for medium-pressure applications and is compatible with systems requiring standardized face types and bolt patterns for easy interchangeability.
