Factory supply high quality blowing rubber seal o-rings washer

A rubber seal in ring form provides a custom interface around an opening or adjoining component. Its dimensions should be developed around the receiving seat and the way the joint closes. The selected cross section determines how the rubber occupies the available space under compression.

Check the inside diameter, outside diameter, and section together rather than choosing from one nominal size. The compound must suit the actual medium, temperature, and movement. The ring's appearance does not establish a pressure rating or a particular processing capability for the finished assembly.

Clean the mating surfaces before fitting and inspect the groove for damage. Place the ring without twist or unnecessary stretch, keeping it seated as the adjoining parts come together. Avoid trapping an edge against a fastener or sharp shoulder. Evaluate the completed joint under its intended conditions, and inspect both rubber and mating surfaces during service. A replacement ring should restore the designed fit rather than compensate for wear or misalignment in the surrounding components.
