X-rings, Quad Rings, Square Rings, X-seals
The sealing principle of the X-Ring is nearly the same as the O-ring sealing. The initial sealing is achieved by the diametrical squeeze in a right-angled groove. The system pressure itself creates a positive sealing force.
X-Rings seals¬†are four lipped seals with a specially developed sealing profile. A wide range of elastomer materials for both standard and special applications allows practically all-liquid and gaseous media to be sealed. X-Rings are vulcanized as a continuous ring. Their annular form with a four-lipped profile characterizes them. X-Rings are supplied in dependence on the AS 568 B and BS 1806 standard.
