Description
Product Overview
The Sterling Seal & Supply SSS 9000IR spiral wound gasket is designed to meet the rigorous demands of modern industrial piping systems. Constructed with a 316 stainless steel inner ring, the gasket offers exceptional corrosion resistance and structural integrity, ensuring a tight seal even under high pressure and temperature fluctuations. The flexible graphite filler complements the metal winding, providing compressibility that adapts to flange irregularities while maintaining a consistent sealing surface.
Engineered to conform to ASME B16.20 standards for Class 150 flanges, this gasket fits 3/4 inch pipe connections with precision. The centering ring incorporated into the design accurately locates the gasket on the flange face, delivering additional radial strength and acting as a compression limiter to prevent over‑tightening. This feature simplifies installation, reduces the risk of flange damage, and extends the service life of both the gasket and the connected equipment.
Temperature performance is a standout attribute, with a proven operating range from -150°F to 850°F. This broad spectrum enables the gasket to function reliably in cryogenic environments as well as high‑temperature applications such as steam, oil, and chemical processing. The combination of metal and graphite layers balances flexibility with durability, delivering a seal that remains intact despite thermal expansion and contraction cycles.
Durability is further enhanced by the high‑quality materials used throughout the gasket. The 316 stainless steel inner ring resists pitting and stress corrosion cracking, while the graphite filler is chemically inert, providing resistance to a wide variety of aggressive fluids. This composition makes the gasket suitable for use with water, oil, gas, and many corrosive chemicals, reducing the need for frequent replacements and minimizing downtime.
Packaging includes six individual gaskets, each individually wrapped to protect against contamination and physical damage during shipping and handling. The compact package dimensions of 6.46 x 5.59 x 1.26 inches make storage convenient, and the lightweight design (approximately 3.07 ounces per gasket) eases inventory management. The product’s ASIN B00JIJVVN4 and its ranking as #54 in Spiral Wound Gaskets reflect its popularity among professionals seeking reliable sealing solutions.

Usage
This gasket is ideal for a variety of industrial applications, including hydraulic systems, pneumatic circuits, and chemical processing plants. Its ability to maintain a seal under high pressure makes it suitable for pump and valve assemblies where leak prevention is critical. The gasket’s flexibility allows it to accommodate slight misalignments in flange surfaces, making it a practical choice for retrofits and new installations alike.
In environments where temperature extremes are common, such as cryogenic gas handling or high‑temperature steam lines, the gasket’s wide temperature tolerance ensures consistent performance. Engineers often select this product for projects that require compliance with ASME B16.5 flange standards, as the gasket’s dimensions and material properties align perfectly with those specifications.
Maintenance crews appreciate the ease of installation and removal. The gasket’s design eliminates the need for specialized tools; a simple hand‑tightening of the flange bolts to the recommended torque is sufficient. This reduces labor time and lowers the overall cost of ownership, especially in facilities where regular maintenance shutdowns are scheduled.
For applications involving aggressive chemicals, the graphite filler’s inert nature prevents chemical degradation, while the 316 stainless steel inner ring resists corrosion from acidic or alkaline solutions. This makes the gasket a reliable component in wastewater treatment plants, petrochemical refineries, and pharmaceutical manufacturing lines where fluid compatibility is paramount.
When used in high‑vibration settings, such as mobile equipment or machinery with dynamic loads, the gasket’s robust construction helps absorb vibrations, preventing premature wear on the flange faces. This contributes to longer service intervals and reduces the likelihood of unexpected leaks that could lead to costly downtime.

FAQ
What pipe sizes does this gasket support?
The gasket is sized for 3/4 inch pipe connections, matching the standard dimensions for Class 150 flanges as defined by ASME B16.5. It can be used with any compatible flange that adheres to those specifications.
Can this gasket be used with corrosive chemicals?
Yes. The combination of a 316 stainless steel inner ring and graphite filler provides excellent resistance to a wide range of chemicals, including acids, bases, and solvents. This makes it suitable for chemical processing and wastewater treatment applications.
How does the centering ring improve installation?
The centering ring accurately positions the gasket on the flange face, reducing the chance of misalignment. It also adds radial strength and acts as a compression limiter, preventing over‑tightening and protecting the flange from damage during assembly.
What is the recommended torque for flange bolts?
While exact torque values depend on the specific flange and bolt size, we generally recommend tightening bolts in a criss‑cross pattern to achieve an even compressive load. Refer to the flange manufacturer’s torque chart for precise values.
Is there a warranty or guarantee for this product?
We offer a limited warranty that covers material defects and manufacturing errors for a period of one year from the date of purchase. Our customer service team can assist with any warranty claims or product inquiries.
