Company Product Introduction

Enterprise product introduction

O-ring seals are suitable for installation on various mechanical equipment. They play a sealing role in a static or moving state under specified temperatures, pressures, and in different liquid and gas media. Various types of sealing elements are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, building machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters.

O-ring seals are mainly used for static seals and reciprocating motion seals. When used for rotary motion seals, they are limited to low-speed rotary sealing devices. Generally, O-ring seals are installed in rectangular grooves on the outer or inner circle to perform the sealing function. O-ring seals can still provide good sealing and shock absorption effects in environments resistant to oil, acids, alkalis, abrasion, and chemical erosion. Therefore, O-ring seals are the most widely used type of sealing element in hydraulic and pneumatic transmission systems.

Dumbbell Ring (Dumbbell-shaped End Face Seal Ring)
The dumbbell ring is a kind of dumbbell-shaped end face static seal, which is used to replace the combination of an O-ring and a backup ring.
Advantages: It is highly resistant to deformation, easy to install, has a long service life, and the material is highly resistant to extrusion.
