Oz Seals revives the use of PK56 robust hydraulic seal for tough conditions
An enduring example of a classic seal design for harsh conditions where shock loads and pressure spikes present an issue is the PK56 profile (or PK58 with bearing/backup rings), which in recent times has been overlooked by seal suppliers and manufacturers all over the world.
The robust PK56 and PK58 hydraulic piston seals in super polymer, rather than the traditional rubber and fabric combination, which can delaminate. The super polymer makes it a long lasting, wear resistant seal for a wide variety of applications with the bonus of superior performance. These applications include hydraulic cylinders for general hydraulic systems and presses, agricultural machinery and mobile hydraulic systems. The efficiency of this heavy duty seal benefits from the low friction provided by the triple lubricated properties in Oz Super Polymer.
