Sterling Seal 304 Stainless Spiral Gasket 12in Pipe Yellow/Gray Pack12

Description

Product Overview

The Sterling Seal 304 Spiral Wound Gasket is engineered for demanding industrial environments where reliability and durability are paramount. Constructed from high‑grade 304 stainless steel, the gasket features a flexible graphite filler that accommodates thermal expansion while maintaining a tight seal under extreme pressure. Each gasket measures 12 inches in diameter, designed specifically for 12‑inch pipe flanges, and is marked with a distinctive yellow and gray stripe to comply with ASME B16.20 identification requirements. The spiral wound architecture provides superior resistance to flange erosion, inward buckling, and turbulent flow, making it an ideal choice for heat exchangers, boiler hand holes, manholes, and other high‑temperature, high‑pressure applications. The pack includes twelve gaskets, ensuring you have sufficient inventory for routine maintenance and emergency repairs.

Usage

Designed for a broad range of hydraulic and pneumatic systems, this gasket excels in applications such as oil and gas pipelines, chemical processing plants, power generation facilities, and marine propulsion systems. Its robust construction allows it to withstand temperatures up to 500°F (260°C) and pressures exceeding 300 psi, providing confidence in both continuous and intermittent operation. Installation is straightforward: ensure flange faces are clean, free of debris, and properly aligned. Apply appropriate bolt lubrication and torque to the recommended specifications to achieve full compression against the guide ring, which prevents damage and guarantees optimal sealing performance. The gasket’s flexible graphite core adapts to minor surface irregularities, reducing the risk of leaks and extending the service life of the flange assembly.
