Description
38R272 Flexitallic Spiral Wound Flange Gasket: Graphite Filler, 304 Stainless Steel Winding, For 3/4 in Pipe
These spiral-wound ring gaskets include a graphite filler material and have an inner ring to provide additional radial strength to prevent gasket buckling and blowout. Ring gaskets sit against the internal edge of the flange, around the pipe bore, and inside the bolts. They are typically positioned onto the raised surface of a raised-face (RF) flange. Ring gaskets install by dropping them into the flange fitting without fully disassembling the joint.
