Custom Silicone O-Rings

O-rings, also known as packing joints, are sealing components shaped like doughnuts that can be used in both static and dynamic applications. These seals are among the most widely used in machinery due to their simplicity, affordability, and reliability. Various materials are utilized for fabricating O-rings, such as neoprene, silicone, polyurethane, nitrile, and others. Different manufacturing processes, including extrusion, transfer molding, injection molding, compression molding, and machining, are used to produce O-rings.

Extruded Silicone Rubber O-Rings

Silicone rubber is a versatile elastomer known for its exceptional performance across a broad temperature range, from -67 °F to +450 °F. Due to its resistance to heat, moisture, chemicals, fungal growth, oxygen, ozone, corrosion, and aging, silicone rubber products are frequently selected for demanding applications. The material exhibits impressive tensile strength, tear strength, elongation, and compression properties.

O-Ring Industrial Applications

O-rings are used extensively across several industries. Common applications include:

  • In the medical field, FDA-approved O-rings are used in syringes, filtration systems, pumps, and connectors.

  • The food processing, water filtration, and beverage dispensing sectors rely on special NSF-61, 3A sanitary, and water service O-rings and seals.

  • O-rings in the electronics industry are used for semiconductor processing and to prevent dust in consumer electronics.

  • The oil and gas industries require O-rings in gas pumps, valves, dispenser fittings, and storage tanks.

Spliced & Vulcanized Rubber O-Rings

Elastostar Rubber Corporation manufactures a wide range of vulcanized silicone O-rings. Available rubber hardness ranges from 20 Shore A to 80 Shore A. These O-rings are offered in standard sizes, shapes, and colors but can be customized to meet specific requirements. The vulcanization process ensures that these joints are as smooth as molded parts.

Fluorosilicone Rubber O-Rings

Fluorosilicone O-rings combine the high and low-temperature resistance of silicone with enhanced fuel and oil resistance. These O-rings are predominantly used in fuel systems and can withstand prolonged immersion in soils, fuels, and abrasive fluids. They also excel in high-temperature environments where the dry-heat tolerance of silicone O-rings is necessary.

Elastostar Extruded Silicone Rubber Tubing Hose

Elastostar Rubber Corporation manufactures silicone rubber tubing and silicone rubber hose, offering a full range of extruded high-quality standard and custom-sized silicone tubing in both English and metric units. The available wall thickness for these products ranges from 0.010 inches to 0.750 inches.

Extruded Rubber T-Seal/T-Shape & Gaskets

Elastostar Rubber Corporation produces both standard and custom-sized extruded silicone rubber T-seal, T-strips, and gaskets. With a wide selection of shapes and wall thicknesses, these seals and gaskets can be customized to fit specific customer needs.
