Spiral Wound Gasket Sterling Seal 9000IR1500316GR600X6 1.5in 600#

Description

Product Overview

The Sterling Seal & Supply SSS 9000IR1500316GR600X6 Spiral Wound Gasket is a premium sealing solution designed for high‑pressure hydraulic and pneumatic systems. Constructed with a 316 stainless steel inner ring, the gasket offers exceptional corrosion resistance and structural integrity, while the flexible graphite filler provides superior compressibility and temperature tolerance. Certified to ASME B16.20 for use with ASME B16.5 flanges, this gasket is rated for Class 600 applications, making it suitable for demanding industrial environments where reliability and safety are paramount.

Key specifications include a 1.5‑inch pipe size, a 600# pressure rating, and an operating temperature range of –150°F to 850°F. The spiral winding design combines metal strips and graphite filler in a tightly wound configuration, delivering consistent sealing performance even under cyclic loading and thermal expansion. The gasket dimensions are compact, with package dimensions of 15 x 11 x 0.5 inches and a lightweight of 4.8 ounces per pack of six, facilitating easy handling and storage.

Usage

This gasket is ideal for a wide range of applications, including oil and gas pipelines, chemical processing plants, power generation facilities, and heavy‑duty manufacturing equipment. Its robust construction allows it to perform reliably in high‑temperature steam lines, corrosive fluid transport, and high‑velocity gas streams. Engineers and maintenance technicians appreciate the gasket’s ease of installation; the centering ring accurately positions the gasket on the flange face, providing additional radial strength and acting as a compression limiter to prevent over‑tightening.

Typical use cases involve sealing connections between carbon steel or stainless steel flanges in systems that operate under extreme pressure and temperature conditions. The gasket’s flexible graphite core adapts to surface irregularities, ensuring a leak‑free seal even when flange surfaces are slightly out of tolerance. This makes it a preferred choice for retrofits, new installations, and critical safety‑related components where downtime must be minimized.
