Permitted pressure

The capability for quenched and tempered steel to resist high contact pressure, the low contact pressure for the Metseal seal and the insensitivity for surface defects, makes it possible for Metseals piston seals to work with very high pressures which are higher then for other seal types. How high is determined by the lubricating properties of the pressure media and which Metseal seal type that is used. Experiences up to 100 Mpa have been made. When the customer so wishes, Metseal can develop and deliver special seals for extreme pressures, based on the techniques and "know how" already in existence.
