Spiral Wounds » Style R - Windings Only

The Style R spiral wound is the most basic and cost effective spiral wound gasket offered. The Style R consists of inner and outer diameters reinforced with plies of metal windings without filler for improved stability, compression, and sealing. Filler material is used between the metal windings. The Style R is used with tongue and groove, male and female, or grooved to flat face flange assemblies.
