Spiral Wound Gasket with Centering Device
PRODUCT OVERVIEW

Reliable Alignment for Superior Sealing

The integrated centering device (outer guide ring) accurately positions the gasket during installation and prevents incorrect placement inside the flange. It also acts as a compression stop, reducing the possibility of over-compression.

These gaskets are widely used in raised face flanges across oil & gas, chemical processing, refineries, power generation, and petrochemical plants where reliable sealing under pressure and temperature fluctuations is essential.

Ferrobend manufactures spiral wound gaskets with centering devices using premium stainless steels, alloy metals, graphite, PTFE, ceramic, mica, and other specialized filler materials to satisfy demanding industrial requirements.
