🔩 What Is a Spiral Wound Gasket?

A semi-metallic gasket made of alternating V-shaped metal strips and soft filler, wound into a strong, resilient sealing element.

✅ Handles high temperatures, pressure changes and flange movement
✅ Resists joint relaxation and flange rotation
✅ Solid metal coils at the inner and outer edges for added strength
✅ Manufactured and marked to ASME B16.20

⚙️ Gasket Types Available

✅ Type R (0105): Basic spiral wound gasket for tongue and groove or male and female flanges.
✅ Type ROR (0106): With outer ring for centring, blowout protection and compression control.
✅ Type RIR (0107): With inner ring to reduce turbulence, erosion and solid build-up.
✅ Type CRIR (0108): Inner and outer rings for Class 900+ and corrosive or toxic media.
