PDEP is a double-acting piston particularly suitable for pneumatic cylinders. It is made of NBR or FKM compounds, with a hardness of 70 Shore A, with special sealing profiles vulcanized onto a central steel plate.
PRESSURE: Up to 10 BAR (1 MPa)
TEMPERATURE: Range -30°C / +100°C
LINEAR SPEED: Up to 0.5 m/s
USE: Reciprocating linear movement
Ø EXTERIOR: Rubber
CONSTRUCTION: Double sealing lip without spring + Reinforcement metal disc

The PDE is a symmetrical piston with double-acting operation for reciprocating straight-line movements. It is a product created specifically for use in hydraulics, in an NBR or FKM compound with a hardness of 85° Shore A and complete with toroidal expansion springs, which ensure an exact radial contact pressure.
PRESSURE: Up to 40 BAR (4 MPa)
TEMPERATURE: Range -30°C / +100°C
INEAR SPEED: Up to 0.5 m/s
USE: Reciprocating linear movement
Ø EXTERIOR: Rubber
CONSTRUCTION: Double sealing lip + Double toroidal spring + Reinforcement metal disc

Gasket is suitable for dynamic seals on a single lip, the external one. It does not require a stop ring as the internal static seal lip, of a more robust shape, serves as a stop against the axial movement of the gasket in its seat. It supports operating pressures up to 8 MPa (80 bar).

Structurally robust gasket and must be mounted with the interposition of a stop ring that prevents the gasket from moving axially in its seat.
The stop ring must not press the gasket into its seat, but must allow a gap of 0.5 ÷ 1 mm. Furthermore, it is necessary to drill a series of holes in the ring which have the purpose of equally dividing the pressurized fluid on the two sealing lips. These seals can be mounted on both piston and cylinder and can withstand pressures of up to 12 MPa (120 bar).

Gasket normally mounted on the piston with a plate as indicated in the technical drawing; the result is therefore a seal that is not completely automatic. They are commonly called caps and can be used with pressures that do not exceed 4 MPa (40 bar).
