Features1

Spiral wound gasket using chemical-resisting VALFLON tape as filler material, these Spiral Wound Gaskets have precedence over other filler materials in sealing corrosive fluids and airtightness, thus are suited as gas in general and vacuum seals.

Features2

An outer ring is attached. The circumferance of the outer ring of the gasket inscribes the bolt of the flange, making gasket centering easy. This ring is also useful as a guide for adjusting the amount of reinforcement and tightening of the gasket. For use with a raised face flange, No. 7596 (with inner and outer rings) is recommended, as deformation of the inner diameter of the gasket is possible.

Features3

Please use a product with inner and outer rings if the pressure rating of the flange is Class 900 (JIS 63K) or greater, or if the nominal diameter of the flange is 650A (26B) or greater.

Features4

Together with excellent corrosion resistance and proper selection of hoop materials, they can be applied to almost all fields of applications.

Features5

Excellent airtightness greatly improves sealing performance against gas in general and vacuum.
