Spiral Wound Gaskets

Spiral wound gaskets have proven to be the most reliable sealing element for use in difficult, critical and arduous duties. Spiral wound gaskets are used in Refinery, Petrochemical, Chemical, Steam lines and Process Industries, where they have many advantages over older types of gaskets.

These gaskets are manufactured to International specifications such as BS, API, ASME, DIN. We also manufacture to customer's specifications

We have a huge capacity to produce precision machined components.

Available in several standard shapes
SWR Spiral Wound Metaillic Gasket without centering ring
SCD Spiral Wound Metallic Gasket with centering device
SOR Spiral Wound Metallic Gasket with centering ring. (Centering ring made of carbon steel stainless steel and other metals)
SIO Spiral Wound Metallic Gasket with inner & outer rings. (Rings are made of carbon steel stainless steel and other metals)
SIOH Spiral Wound Metallic Gasket with outer ring supplied with bolt holes and inner rings
SIR Spiral Wound Metallic Gasket with inner rings. (Rings generally of stainless steel)

Spiral Wound Metallic Gasket 'W' type and Spiral Wound Metallic Gasket 'Inverted W' type are also available.
