Spiral Wound Gasket with Carbon Steel Outer Ring, SS316L Winding, and Graphite Filler - Style GR

The DEMINAS spiral wound gasket Style GR provides a reliable seal for standard pipe flange connections. It features a carbon steel outer ring with epoxy coating, SS316L winding, and a flexible graphite filler. Unlike the GRI style, the GR does not include an inner ring — making it the right choice for class 150 applications and flanges where an inner ring is not specified.

Technical Specifications

• Style: GR — CS outer ring / SS316L winding / graphite filler (no inner ring)
• Outer Ring: Carbon Steel, epoxy coated
• Winding Material: SS316L stainless steel
• Filler Material: Flexible graphite
• Standard: ASME B16.20

GR vs GRI — Which Do You Need?

The GR style suits ASME class 150 and standard-pressure flanges. If you are working with class 300 or above, a high-pressure steam line, or a small-bore flange, consider the GRI style which adds an inner ring for additional filler support.

Applications

• General-purpose pipe flanges in chemical plants and utilities
• Water treatment and process pipework
• Low-to-medium pressure steam systems
• ASME class 150 flange connections
