Sterling Seal Spiral Wound Gasket SSI90003304GR150X12 3″ Pipe 150#

Description

Product Overview

The Sterling Seal SSI90003304GR150X12 spiral wound gasket is engineered for demanding industrial environments where reliability and durability are paramount. Constructed with 304 stainless steel windings, a graphite filler core, and a carbon steel outer ring, this gasket combines the corrosion resistance of stainless steel with the compressibility of graphite to maintain a tight seal under fluctuating pressures and temperatures. Its dimensions—4″ ID, 5.375″ OD, and a 3″ pipe compatibility—make it an ideal fit for standard 3″ pipe flanges, while the pressure class of 150 psi ensures performance well within the specifications of most hydraulic and plumbing systems. The gasket complies with ASME B16.20 identification markings, guaranteeing traceability and adherence to industry standards. Each pack contains twelve gaskets, providing ample inventory for maintenance cycles and large‑scale projects.

Usage

Designed for a broad range of applications, this spiral wound gasket excels in high‑temperature, high‑pressure scenarios such as hydraulic power units, pneumatic compressors, heat exchangers, boiler hand holes, and manholes. Its robust construction allows it to withstand temperatures up to 600 °F, making it suitable for steam and hot‑oil services. The gasket’s flexible filler accommodates slight flange misalignments, reducing the risk of inward buckling and turbulent flow that can lead to efficiency losses. Installation is straightforward: ensure flange faces are clean, apply appropriate bolt lubrication, and compress the gasket fully against its guide ring to achieve optimal sealing performance. The gasket’s design also minimizes flange erosion, extending the service life of both the gasket and the mating components.
