Hydraulic & Pneumatic Seals

Durable and Performance Oriented Hydraulic and Pneumatic Seals

Hydraulic and pneumatic seals are sealing components used for applications with rotary or reciprocating motions. In applications, hydraulic seals separate fluids, while pneumatic seals separate gases.

Both support the conversion of fluid power into linear motion. SSP Seals’ stocks a wide range of hydraulic and pneumatic seals to meet the various needs of industrial applications in terms of design, manufacturing, and application performance.

Types of Hydraulic and Pneumatic Seals

SSP manufactures industry-grade seals that perform exceptionally in demanding environments. Our hydraulic and pneumatic seals inventory includes the following:

  • Piston Seals: These seals prevent the leakage of pressurized fluids by creating a sealing between the cylinder and the piston. Piston seals are used in both pneumatic and hydraulic seals. Available as single-acting and double-acting types, these seals can also be used with guide rings and back-up rings.
  • Back-up Rings: These seals are designed to solve the problem of seal extrusion. They can also be used to increase system pressure safely.
  • Vee Packs: These are seals designed with multiple vee rings. They also comprise male and female adaptors, and are compatible with single and double acting cylinders.
  • T-seals: These seals can be designed in both rod and piston styles to prevent extrusion and spiraling. T-seals are also employed as replacements for existing O-rings.
  • Wipers: Commonly known as scraper seals, these wipers help the ingress of external contaminants, which can damage the sealing system, as well as the application machinery. We also design many seals with secondary lips to capture remnants that may have escaped the sealing.
  • O-rings: A popular product in our inventory, our O-ring products are designed to prevent gas or fluid leakage within a system.
  • Rod Seals: These hydraulic seals are used to prevent fluid leakage within cylinder.
  • U-cups: These seals are used for low pressure systems. Available in a variety of materials and sizes, these U-cups deliver low friction for ‘out-of-round’ components.
  • Guide Rings: As the name suggests, this seal type is designed to guide pistons and piston rods within a cylinder.
