Piston Rings, Packing Rings and Wiper Rings

Piston Rings : ORIENTAL piston rings are made as per piston and cylinder dimensions and specifications to suit various gas services. Accurate diameters with appropriate gaps help users to achieve best possible results while in operation under tough conditions. Various designs and suitable materials are chosen for service in different compressors to get optimal results.

Rider Rings : ORIENTAL rider rings, similar to the piston rings are chosen in accordance to the piston rings and give optimal support to the expensive piston and protect the even more expensive liner. Materials normally softer than the liners are chosen for such protection.

Rod Seal Rings : ORIENTAL produces high circularity Packing rings or seal rings with accurate thickness so that there is no passage between the piston rod and the packing cups, ensuring accurate sealing and lowest losses of expensive gases. The seal rings with accuracy also protect the piston rod from any sagging or scoring while containing the gases from leaking through the chamber into the crank case. Here again we offer variety of materials including high end durable polymers to run smoothly for longer life in different gas applications. Packing rings are lapped in very high pressure applications to get even better sealings with the cups.

Oil Wiper Rings : ORIENTAL manufactures these rings again in soft metals and at times in polymers also. These avoid oil or oil fumes arising from the crank case through the cross head and connecting rods to enter the gas chamber, thus protecting wastage of expensive oil and saving the gas from contamination.
