Ring Gaps

Selection of the proper ring gap configuration is important in piston or sealing ring applications. Acceptable leakage rates, size of the ring, and type of assembly are factors that help determine the proper gap configuration of the piston or sealing ring.   Precision Ring’s engineering team can select the proper gap configuration for a specific application.   

Primary & Secondary Sealing 

In the case of an expanding ring, primary sealing is established between the outside diameter (OD) of the ring’s surface and the cylinder bore. Secondary sealing is created by contact between the ring's side face and groove wall.
