Spiral Wound Gasket Styles


The construction of this gasket is made of circular metal windings with filler and an outer guide ring. The standard pipe size gaskets are made to ASME B16.20 or EN 1514 (see also style 913M).

The 913M is the standard spiral wound gasket with an inner and outer ring. The purpose of the innerring is to fill out the space between the flanges, avoiding turbulence in the flow of the fluid or as protection against corrosion or erosion. It is also used as a compression limit. Gaskets with PTFE filler have a tendency to buckle inward, thus the use of an inner ring is required by ASME B16.20 or EN 1514. Inner rings are also required with ASME standard spiral wound gaskets with flexible graphite fillers unless the purchaser specifies otherwise and some sizes and pressure class require inner rings regardless of filler material.
