Piston Rod Seals

BORSIG ValveTech piston rod seals have the task of sealing the cylinder chamber at the piston rod passage to the atmosphere (crank end). The design and specification of the dimensions is carried out in relation to the parameters of the compressor, e.g. suction and discharge pressure, medium, etc.

Decades of experience and the use of state-of-the-art high-performance sealing elements guarantee good service life and low pressure losses.

Should reconditioning of a worn-out  piston rod seal be required, the wear signs on the sealing elements and internal parts are to be inspected at manufacturer’s plant, followed by remedial actions enabling the repeated service of the restored piston rod seal.
