O-Rings for Industrial & Generator Applications

High-Performance O-Rings for Reliable Sealing Solutions

O-rings are one of the most widely used sealing components in industrial equipment. With a simple circular cross-section design, O-rings create an effective seal by being compressed between two mating surfaces, preventing the leakage of gas or liquid.

At EN-Generator, we supply high-quality O-rings designed for generator sets, engines, valves, pumps, pipelines, and other industrial systems, ensuring stable performance even under demanding operating conditions.

Custom sizes and special specifications can also be manufactured according to your drawings or samples.

Typical Applications of O-Rings

O-rings supplied by EN-Generator are widely used in:

• Diesel and gas generator sets

• Engine sealing systems

• Hydraulic and pneumatic systems

• Pumps and valves

• Pipe fittings and flanges

• Industrial machinery and mechanical equipment

• Automotive and heavy-duty equipment

Proper material selection ensures reliable sealing performance under high pressure, high temperature, or corrosive environments.

How O-Rings Work – Sealing Principle

An O-ring creates a seal by being compressed inside a groove between two mating surfaces. When pressure is applied, the O-ring deforms to fill the gap, forming a tight barrier that prevents leakage.

Key factors affecting sealing performance:

• Correct groove design

• Proper compression ratio

• Suitable material compatibility

• Clean installation environment

Installation Tips for Better Sealing Performance

• Ensure the groove and O-ring are clean before installation

• Avoid sharp edges that may damage the O-ring

• Use appropriate lubricant if required

• Do not overstretch or twist the O-ring

• Replace aged or damaged O-rings in time

Correct installation helps extend service life and improves system reliability.
