They commonly include forms such as O-rings, flat gaskets, lip seals, and bellows, each chosen for how it seals under specific pressures and motions.
Materials used for suojakumeita vary by application and include nitrile rubber (NBR), fluorocarbon (FKM, also known
In practice, suojakumeita are placed in grooves or mating surfaces and compressed to form a seal. Some
Maintenance focuses on inspecting for cracking, compression set, extrusion, or loss of elasticity. Degraded seals are
