MAHLE is the largest piston ring manufacturer in the world, and MAHLE Performance piston rings are the most extensively tested and technically advanced 

Our rings function in sets, usually—a top compression ring, second groove compression (or oil scraper) ring, and oil control ring—and range from 1.125″ to 8.875″ bores. If you're questioning the set you need, our engineers can recommend the right one out of the thousands we offer. Learn more about the piston rings we manufacture below.

Complete piston ring kit in standard design for pistons with diameter 82,75 mm. This set contains three piston rings with heights 1,2 mm, 1,5 mm a 2,0 mm.

We supply an extensive range of piston rings for passenger car, truck, bus, tractor, air brake compressor, forklift, motorcycle, generator and various 

Simply put, piston rings form a seal between the piston and cylinder wall, which prevents pressurized combustion gases from entering the oil 

F16J9/061 — Piston-rings, e.g. non-metallic piston-rings, seats therefor; Ring sealings of similar construction using separate springs or elastic elements expanding the rings; Springs therefor ; Expansion by wedging using metallic coiled or blade springs; F16J9/063 — Strip or wire along the entire circumference

A piston ring is an engine component that seals and aligns the piston to the engine block cylinder wall. The sealing is to keep combustion gas between the top of the piston and the valves, creating power.

A piston ring must possess both spring-like tension and the properties to become a true circle when closed simultaneously. Piston rings keep a close contact 

Your pistons rings are responsible for three important jobs. Sealing the combustion chamber, supporting heat transfer from the piston to the cylinder wall and regulating oil consumption. No matter the engine make or bore size we've got the piston rings you need with a variety of ring thicknesses. With rings from the top names like Total Seal

Between the piston and cylinder, the piston ring is a part that is needed for an engine to work efficiently. Piston Rings have 4 main functions.
