Back-up Rings
Back-up rings are the most common anti-extrusion devices employed in dynamic and static sealing, designed to prevent the migration of sealing material into the extrusion gap under the system pressure. Parker offers a wide range of back-up ring geometries and materials to suit every seal type and application. They are open or closed shapes for snap assembly made of a broad range of compounds which are highly resistant to thermal or mechanical stress. Parker back-up rings help reduce costly downtime and ensure long-term functional reliability.

HIGH PRESSURE OIL SEALS
0 out of 5(0)The rotary shaft oil seal is an indispensable component in lubricated rotating equipment and must be chosen with caution in order to ensure that the correct design and materials are used to provide a long-lasting life for the rotating equipment.
These variations of the G and M type seals are engineered to withstand pressure up to 10 BAR (1 MPa), although this limit has been exceeded in some applications. These seals are available with or without an additional dust lip. The G type and its high pressure variants show a metal insert covered by rubber, while the M type and its variants offer a bare metal body on the outside diameter.

WIPER SEALS
0 out of 5(0)Rod wipers for alternative linear movements have been designed to give first-class protection to seals and driving bodies in hydraulic and pneumatic cylinder applications.
The main function of the rod wiper is to keep the rod clean from any possible impurity.
The •FP• rod wipers have a chamfer on the outside diameter to facilitate the press fitting into the housing. To simplify the installation, the bore should have a chamfer as per DIN 3760.
