Y-shaped rubber O-ring typical lip seals

 

Y-shaped cross section of the rubber O-ring Y-shaped, is a typical lip seals. Y-shaped rubber O-ring according to the aspect ratio of the cross-section of different width can be divided into Y-type rubber O-ring, narrow Y-type rubber O-rings and Yx-ring and so on. Wide cross-section of the pressure-resistant Y type rubber O-ring is slightly smaller than the narrow Y-shaped rubber O-ring, is only applicable to P <20MPa work environment, and narrow Y-type rubber O-rings can be used for working pressure P <32MPa occasions.

 

Y-shaped rubber O-ring in accordance with two lips are the same height, and can not be divided into shaft contour lip Y type rubber O-ring, not lip contour Y type rubber O-rings and shaft hole holes universal Y-shaped contour lip rubber O-ring.

 

Y-shaped rubber O-ring manufacturing different materials, can be divided into Y-shaped rubber nitrile rubber O-ring, fluorine rubber Y-shaped rubber O-ring, polyurethane rubber Y-shaped rubber O-rings.

Y-shaped rubber O-ring Application:

 

Widely used in reciprocating dynamic sealing device, its life above the O-ring. Applicable operating pressure Y type rubber O-ring is not greater than 40MPa, operating temperature of -30 ~ 80 ?, working speed range: NBR uses when fabricated as 0. 01 ~ 0 6m / s; when the fluorine rubber production. is 0.05 ~ 0.3m / s; when polyurethane rubber production, compared with 0.01 ~ lm / s. Y-type sealing rubber O-ring, life and work pressure limit when different collar are polyurethane rubber material is preferred.
