Which method is better? O-ring face seal.

By Brian on 09 Oct 22:39 1 answer 0 comments

HI Im using Autocad and need help on achieving an air tight seal (<1psi) between a cartridge and the shell that it goes into.

attached in the picture are two designs . They are both cylinders and i'm afraid that the complexity of the cavity will not be feasible for injection molding.

The casing is Black
The cartridge is Blue
The O-ring is orange

My question is can either of these methods be used ? If so, which one works more effectively?

    Hi dear,

    It depends to the force direction.If there is axial force you can use face to face sealing and if you have radial force you can use radial sealing.if there is not you can make force by your design. :)
