In any sealing application, correct O-ring selection is the result of a number of design considerations including dimensions, chemical compatibility and the ability to resist pressure and temperature extremes. It is helpful to pay particular attention to some basic sealing concepts when selecting an O-ring for your application. These include: Sealing Pressure - Sealing pressure is the force exerted by compression of the seal between the mating surfaces forming the gland itself and external forces (i.e. the fluid being sealed) transmitted through the seal. A physical barrier is formed when the force from compressing the seal and pressure applied by the fluid being sealed causes the seal to fill all leak paths. Products & Services
Dynamic seals include oil seals, hydraulic and pneumatic seals, exclusion seals, labyrinth seals, bearing isolators, and piston rings. They create a barrier between moving and stationary surfaces in applications such as rotating shafts and pistons rings. This is a general search form; more detailed search forms are available.
Mechanical seals including mechanical face seals, bellows, gas seals, and cartridge seals.
Compression packing seals or gland seals are deformable materials used to prevent or control the leakage of fluid between surfaces that move in relation to each other.
Oil seals and grease seals have a flexible lip that rubs against a shaft or housing to prevent the leakage or ingress of fluids and dirt.
Exclusion seals are comprised of wipers, scrapers and V-ring seals.
