Parker OD-type piston rod seal combination
   OD type rod seals are made of PTFE rod seal ring and O-ring components. Hydraulic cylinder and piston rod seal.

   OD seals is particularly applicable to the control cylinder, servo systems, machine tools, quick response cylinders and construction machinery. It is used in conjunction with the dust seal lips can achieve optimum sealing characteristics.

This seal has the following advantages:

● small dimensions.

● minimum friction starting and movement, even at low speeds but also to ensure smooth movement, no creeping phenomenon.

● wear resistance.

● anti-extrusion.

● high temperatures.

● Since the seal ring has a high resistance to chemical corrosion characteristics of medium, and choose different materials O-ring, OD seals can be applied to almost all media.

● Due to the special shape of the seal structure, the film has a good oil return characteristics.

● can provide up to a diameter of 2500mm products.

1. Standard Material

Slide ring: Polon ® 052, a modified PTFE + 40% bronze.

O-ring: N0674, Shore hardness of about 70 NBR rubber.

If the special requirements (pressure, temperature, speed, etc.), please contact our advisory service department, they will recommend to you the appropriate materials and structures.

2. Applications

Working pressure: ≤400bar *

Working temperature: -30 to + 100 ℃ **

Surface speed: ≤4m / s

* Reducing the gap extrusion conditions, can withstand 600bar working pressure (H7 / f7)

** Standard temperature deviations, please consult the appropriate Parker O-rings.
