What are Static Seals?
Static seals are categorized as seals whose mating gland parts do not move relative to one another. There is no motion in the sealing surface between the seal and gland.
Static Axial Seals
A static axial seal is one in which there is no motion and the sealing occurs parallel to the seal center-line. The sealing occurs on the top and bottom of the seal, aka the face of the seal.
Static Radial Seals
The sealing surfaces are perpendicular to the seal centerline in a radial seal orientation. The sealing surfaces are on the inner and outer diameter, aka the cross section of the o-ring. There are two variations of a radial seal. One is a piston seal where the groove is on the piston, illustration to the right. The second is a rod seal where the groove is on the bore, illustration to the left.
The Bonded Seal was originally designed to replace copper type washers in high-pressure systems. Often used as bolt seals in hydraulic equipment, today bonded seals (commonly known as Dowty Seals) are finding usage in many and varied applications throughout various industries.
O-Rings are circular sealing elements with circular cross-sections, and are mainly used in static applications. The sizes are specified by the inside diameter and the cross section diameter. Our O-rings are manufactured according to metric and imperial international standards such as AS 568B, DIN ISO 3601 and JIS. Custom sizes of almost any dimension are possible, such as miniature O-rings, special O-rings with large dimensions and continuously molded and spliced cord.
X-Rings have a sealing function doubling that of an o-ring, and can be used in numerous static and dynamic sealing applications. Compared to a standard o-ring, the four-lobed X-Ring profile maintains twice the sealing surface. The double-seal action requires less squeeze to maintain an effective seal function. With a reduction in squeeze, this yields lower friction and prolonged seal life.
