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.
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.
Metal bellows perform a number of tasks including sealing environments, carrying gases, liquids and slurry, and mechanically coupling for electrical contact.
O-rings are solid-rubber seals that are shaped like a doughnut. When pressed between two mating surfaces, O-rings block the passage of liquids or gases.
Solid elastomeric rings are compression seals of differing cross sections. Some examples are X or multiple rings, rectangular rings, tetraseals, trapezoid rings, T-section rings, delta rings, D-rings, H-rings, heart rings, and diamond rings.
