O-ring 16x2,5 PTFE white

O-ring 16x2,5 PTFE white is an O-ring: a sealing ring with a circular cross-section. Inner diameter: 16 mm, cross-section: 2,5 mm, outer diameter: 21 mm. Material: PTFE. Dimensions according to DIN 3771. An O-ring is a single elastomer ring. It is compressed in the groove during assembly, and the pressure of the medium then deforms it further, increasing the contact force on the sealing surfaces, so no additional clamping parts are needed. It is used for static and dynamic joints in hydraulic and pneumatic systems.
