P76: Hydraulic Piston Seals, Sealing Solutions Manufacturer, Supplier, Exporter

Max Spare : P76

Profile : Piston Seals

Details :

P76 is a robust heavy duty double acting piston seal. P76 seal consists of 6 parts, elastomeric energiser ring, Bronze Filled PTFE sealing ring, two backup rings made of Thermoplastic polymers and two bearing rings. The elastomeric ring energises the sealing ring to force it against cylinder bore, providing a sealing function at low pressure. The two backup rings prevent gap extrusion of the sealing ring at high pressures. Two bearing rings make contact with cylinder bore which guide the piston during heavy load condition.
