Quad Rings

Quad Rings are a double-acting sealing rings with four blades.

They are used both for static and, prevailingly, for dynamic sealing.

Its application is limited by the sealed pressure and by speed.

Advantages:

Lower initial compression => lower friction, lower wear, longer service life
The four blades result in a higher packing power and, at the same time, create a lubrication groove, which is very favourable in dynamic packing
High stability and dynamic applications
Prevents the rotation in groove

Dimensions:

Similarly to the O-rings, the Quad Rings are delivered in the dimension range in accordance with the Federal Standard AS 568 A a, thus being interchangeable.

Their dimensions are determined by the inside diameter d and by the w cross-section.

Quad ring ø d x w

The Quad ring standard thickness data are: 1,78 mm; 2,62 mm; 3,53 mm; 5,33 mm; 7,00 mm

Application:

Pressure: up to 400 bar ( 500 bar with PTFE ring)
Temperature: – 50 °C up to + 200 °C depending on material of the X-ring
Speed: 0,5 m/s
