PTFE Piston Rings & Rider Rings

Product Code : 12

Piston rings, rider rings and bands are manufactured in various designs:

The function of PISTON RINGS, mounted on the pistons of lubricated or non-lube (oil free) compressors, are designed to ensure that the gas is compressed and to provide a seal between the piston and the cylinder.
The function of RIDER RINGS, used mainly in oil free or mini-lube compressors, is to support or guide the piston and rod assembly and prevent contact between the piston and the cylinder (risk of seizure).
