PRODUCT TYPE: X-Ring

Seal Profile: XR

Lip/Base Material: 70 Nitrile

PRODUCT SPECIFICATIONS

Series: XR
Inside Diameter: 7.975 Inch
Width: 0.21 Inch
Material: 70 Nitrile

DESIGN SPECIFICATIONS

Optimized sealing effect (good pressure distribution over square cross-section)
Low friction due to lower contact forces lubricant depot possible between the sealing lips
High stability in dynamic applications due to almost square cross-section
Lower radial preload required
No interference by separation rate

FUNCTION

Sealing effect due to cross-sectional deformation after installation and axial or radial compression in the installation space
In the operating state, media pressure reinforces the sealing function

PRODUCT ADVANTAGES
