Spiral Wound Gasket Sterling Seal 9000IR8316GR300 8″ Pipe 300# 316SS

Description

Product Overview

The Sterling Seal and Supply, Inc. Spiral Wound Gasket model 9000IR8316GR300 is a premium sealing solution designed for high‑pressure industrial applications. Constructed with a 316 stainless steel inner ring, the gasket offers exceptional corrosion resistance and structural integrity, while the flexible graphite filler provides excellent compressibility and thermal conductivity. This combination ensures a reliable seal across a wide temperature range of -150°F to 850°F, making it suitable for both cryogenic and high‑temperature environments. The gasket conforms to ASME B16.20 standards for Class 300 flanges, guaranteeing compatibility with a broad spectrum of pipe sizes, including the 8″ nominal pipe size specified in the product data. Its spiral wound construction delivers uniform pressure distribution, reducing the risk of leakage and extending the service life of the flange assembly. The product dimensions of 15 x 11 x 0.5 inches and a weight of 1.8 pounds facilitate easy handling and storage.

Usage

This gasket is ideal for use in hydraulic and pneumatic systems where reliable sealing is critical. It performs exceptionally well in chemical processing plants, oil and gas refineries, power generation facilities, and water treatment installations. The 316 stainless steel inner ring resists aggressive media such as acids, alkalis, and saline solutions, while the graphite filler accommodates thermal expansion and contraction without compromising seal integrity. Installers will find the gasket straightforward to position thanks to the centering ring, which accurately locates the gasket on the flange face and acts as a compression limiter. The design supports quick assembly and disassembly, reducing downtime during maintenance. Whether the application involves high‑pressure steam, chilled water, or aggressive chemicals, this spiral wound gasket delivers consistent performance.
