Description
Product Overview
The Sterling Seal SSI900014304GR300X6 is a premium spiral wound gasket designed specifically for 14″ pipe flanges. Each gasket features a core of graphite filler sandwiched between 304 stainless steel windings, delivering a combination of high temperature resistance and exceptional pressure containment. The 304 stainless steel windings provide corrosion resistance in aggressive industrial environments, while the graphite filler offers compressibility that maintains a tight seal even as temperatures fluctuate. The gasket dimensions—14.625″ ID and 19.125″ OD—match standard 14″ pipe specifications, and the pressure class rating of 300# ensures reliable performance in demanding hydraulic and pneumatic systems. All units are etched with ASME B16.20 identification markings, guaranteeing correct orientation and compliance with industry standards. Packaged in a six‑piece case, these gaskets are ready for immediate deployment in a variety of applications, from heat exchangers to boiler hand holes.
Usage
These spiral wound gaskets excel in high‑temperature, high‑pressure settings where traditional solid‑metal gaskets may struggle. Typical installations include heat exchangers, boiler hand holes, manholes, and high‑temperature hydraulic manifolds. The flexible graphite core absorbs thermal expansion, preventing flange distortion and reducing the risk of leaks during temperature cycling. Engineers and maintenance technicians appreciate the gasket’s ability to maintain seal integrity in environments ranging from 300 °F to 800 °F, making it suitable for chemical processing, oil and gas pipelines, and power generation equipment. Proper installation requires clean, flat flange faces and the use of compatible bolting materials; the guide rings on the gasket should be fully compressed to achieve optimal sealing performance.

FAQ
What flange types are compatible with this gasket?
The SSI900014304GR300X6 gasket is compatible with both flat‑face and raised‑face flanges that conform to standard 14″ pipe dimensions. It works well on carbon steel, stainless steel, and alloy flanges, provided the flange surfaces are clean and free of damage.
Can the gasket be reused after removal?
Spiral wound gaskets are designed for single‑use applications to ensure optimal sealing performance. Re‑using a gasket can compromise its compressibility and may lead to leaks. For best results, replace the gasket each time the bolted joint is opened.
What temperature range does the gasket support?
The combination of 304 stainless steel windings and graphite filler allows the gasket to operate safely from ambient temperatures up to approximately 800 °F (427 °C). This makes it suitable for most industrial heat‑exchange and boiler applications.
How do I ensure proper compression of the guide rings?
During installation, tighten the bolts evenly in a star‑pattern sequence until the guide rings are fully compressed against the flange faces. This prevents inward buckling of the gasket and maximizes sealing efficiency. Use a calibrated torque wrench to achieve the recommended bolt load for your specific flange material.
Is bolt lubrication required?
Yes, applying a suitable bolt lubricant reduces friction, allowing the bolts to achieve the correct preload without excessive torque. This helps maintain the gasket’s compression and extends the life of both the bolts and the sealing assembly.
