316 SS Spiral Wound FG, 316 SS IR, 316 SS OR
Spiral wound gaskets listed below consist of a 316 stainless steel inner ring, 316 windings with flexible graphite filler, and a 316 outer ring. Spiral wound gaskets are metallic gaskets consisting of an outer centering ring (also known as OCR, OR, or an outer guide ring), metallic windings with a soft filler material, and a solid inner ring, or any combination of the three. These gaskets are manufactured to meet specifications as outlined in ASME B16.20 (previously covered by API 601). Spiral-wound gaskets can handle more harsh and varied operating conditions than non-asbestos sheet gaskets in general. They are available in multiple materials and configurations.
