Description
Product Overview
The Sterling Seal and Supply, Inc. API 601 9000IR2304GR300 Spiral Wound Gasket is engineered for demanding industrial applications where reliability and durability are paramount. Featuring a 304 stainless steel inner ring, the gasket provides a corrosion‑resistant barrier that maintains its integrity even when exposed to aggressive chemicals and high‑pressure environments. The flexible graphite filler, wound in a precise spiral pattern, offers exceptional compressibility, allowing the gasket to conform to uneven flange surfaces and maintain a tight seal throughout the service life. Designed for 2″ pipe size and 300# class flanges, this gasket meets API 601 specifications, ensuring compatibility with both flat‑face and raised‑face flange designs. Its temperature range of –320°F to 850°F covers cryogenic to high‑temperature processes, making it suitable for a wide variety of sectors including oil and gas, petrochemical, power generation, and heavy‑duty manufacturing. The compact package dimensions of 4.37 x 4.37 x 0.16 inches and lightweight construction (5.64 ounces) simplify inventory handling while delivering the performance expected from a premium sealing solution.
Usage
In practical terms, this spiral wound gasket excels in applications where flange connections must endure cyclic pressure fluctuations and temperature extremes. It is commonly installed in hydraulic and pneumatic systems that require a leak‑tight seal for high‑pressure fluid transfer, such as pump and valve assemblies, pressure vessels, and pipeline junctions. The gasket’s 304 stainless steel inner ring provides a hard, non‑reactive surface that resists wear, while the graphite filler absorbs thermal expansion and contraction, preventing gaps that could lead to leaks. Installation is straightforward: the gasket is placed between the mating flange faces, and the bolts are tightened to the recommended torque, allowing the spiral winding to compress evenly. Because the gasket can accommodate both flat‑face and raised‑face flanges, it reduces the need for multiple inventory items, streamlining procurement for maintenance teams. Its ability to perform reliably in environments ranging from cryogenic cooling loops to high‑temperature steam lines makes it a versatile choice for facilities that operate across a broad temperature spectrum.

FAQ
What flange types are compatible with this gasket?
The gasket is designed for both flat‑face and raised‑face flanges. It fits 2″ pipe connections and 300# class flanges, making it suitable for a wide range of standard flange configurations used in hydraulic, pneumatic, and process piping systems.
Can the gasket be reused after removal?
While the gasket is engineered for durability, re‑use is generally not recommended for critical applications. The spiral winding may lose its optimal compression characteristics after removal, potentially compromising the seal. For best results, install a new gasket each time the flange assembly is opened.
How does the temperature range affect performance?
The graphite filler remains flexible across the full temperature spectrum, from –320°F to 850°F. At low temperatures, the filler retains its compressibility, preventing gaps caused by contraction. At high temperatures, the stainless steel inner ring maintains its structural integrity, ensuring the gasket continues to provide a reliable seal without deformation.
What maintenance practices help extend gasket life?
Regular inspection of flange surfaces for wear, corrosion, or debris is essential. Keep bolt torque within manufacturer‑specified limits to avoid over‑compressing the gasket, which could damage the spiral winding. Periodic cleaning of the flange faces with appropriate solvents will prevent contamination that could impair sealing performance.
Is this gasket suitable for chemical processing applications?
Yes. The 304 stainless steel inner ring offers excellent resistance to many chemicals, including acids, alkalis, and saline solutions. Combined with the inert nature of graphite, the gasket can be employed in environments where chemical exposure is a concern, provided the specific chemical compatibility is verified for the intended service conditions.
