- Temperature Tolerance: These seals can operate effectively in a wide range of temperatures, from extreme cold to intense heat, ensuring reliable sealing in harsh conditions.
- Durable Construction: S-Seals are made from advanced elastomers and reinforced with metal or other durable materials to enhance their strength and longevity.
- Enhanced Sealing Capability: The unique design of S-Seals allows for excellent sealing performance, even in applications with large pressure fluctuations and varying temperatures.
- Resilience to Chemical Exposure: S-Seals are resistant to a wide range of chemicals, including corrosive fluids and gases, making them suitable for use in aggressive environments.
Common Applications of S-Seals
S-Seals are used in a variety of industries where high performance under challenging conditions is required:
- Oil and Gas Industry: S-Seals are commonly used in wellheads, blowout preventers (BOPs), valves, and other critical components in the oil and gas industry, where they provide reliable sealing under high pressure and temperature conditions.
- Subsea Equipment: In subsea applications, S-Seals ensure the integrity of sealing systems in deepwater drilling and production operations, where extreme pressures and temperatures are common.
- Petrochemical Processing: S-Seals are used in chemical processing plants, particularly in applications involving aggressive chemicals and high temperatures, where reliable sealing is essential to prevent leaks and ensure safety.
- Aerospace: S-Seals are used in aerospace applications where high-pressure sealing is required, such as in hydraulic systems, fuel systems, and landing gear assemblies.
- Industrial Machinery: S-Seals are also used in heavy-duty industrial machinery, particularly in hydraulic and pneumatic systems, where they provide reliable sealing under demanding operating conditions.

EPDM (Ethylene Propylene)
EPDM S-Seals, materials, O-rings, gaskets, & custom molded parts can operate over a wide temperature range, and are compatible with glycol fluids that cause problems for most typical elastomeric seals.
NBR (Nitrile, Buna-N)
Nitrile S-Seals, O-rings, gaskets, & custom molded parts are very oil-resistant, have strong mechanical properties, are resistant to wear, and are relatively inexpensive. These properties make Nitrile the most commonly used general purpose O-ring, gasket, & custom molded part material.
HNBR (Hydrogenated Nitrile)
Hydrogenated Nitrile S-Seals, O-rings, gaskets, & custom molded parts offer higher strength and reduced degradation at high temperatures compared to conventional Nitrile materials. These properties make HNBR materials popular in the oil and gas industry, as well as many applications in the chemical industry.
XNBR (Carboxylated Nitrile)
XNBR S-Seals, O-rings, gaskets, & custom molded parts are similar to Nitrile, but the backbone has been chemically modified with a Carboxylic Acid group. The resulting elastomer is a Nitrile rubber with outstanding abrasion and chemical resistance, superior to that of traditional Nitrile.
