Molded O Rings by Hi- Nuc Engineering Private Limited

The O-ring is a simple and versatile seal that can be used in thousands of applications. O-rings are manufactured in a wide variety of compounds to suit your every need.

Static Sealing
Most O-Rings are used in static service (the O-Ring and metal surfaces remain relatively fixed). They may be applied as face seals or radial seals. In face seal applications, the O-Ring should seat against the low pressure side of the groove.

Dynamic Sealing
The O-Ring moves relative to the mating surface. A moving seal may be further classified by the type of motion: reciprocating, oscillating, or rotating. The greatest number of dynamic seals are used in reciprocating service in cylinders, valves, and linear actuators. Oscillating motion is encountered in swivels and valve stems. When an O-Ring is used on a rotating shaft, it should be limited to light duty where the shaft speed is low and some fluid bypass is acceptable.

Materials
Buna-N, Viton, EPDM, Silicone, PTFE, Polyacrylate

Durometer Selection
70-durometer hardness should be used wherever possible as it offers the best combination of properties for most O-Ring applications. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.
