3 Inch O Rings

What is 3 inch O rings

• 3 inch O rings are high-quality sealing rings with specific sizes and shapes, which are widely used in various industrial fields and application scenarios. It is made of high-quality elastic materials (such as rubber) and can provide reliable sealing performance to prevent the leakage of liquid, gas, or other media.

Features and Benefits of 3 inch O rings

• 3 inch O rings have good wear resistance, chemical corrosion resistance, and high-temperature resistance, and can maintain a sealing effect in various harsh working environments.
• The "O" cross-section design of the O-ring enables it to form an effective seal at the connection part, fill the gap, and prevent leakage. It can adapt to pressure changes and temperature fluctuations and maintain stable sealing performance.

Usage range

Including automobiles, machinery, chemicals, aerospace, etc. They are generally used to seal pipes, joints, valves, pistons, piston rods, and other connecting parts to ensure the normal operation of the system and prevent leakage.

Exact dimensions

3 inches means that the inner or outer diameter of the O-ring is 3 inches. We provide precise dimensional control to ensure that the O-ring fits perfectly with the required connection part and provides a reliable sealing effect.

Can be customized

Provide customized 3 inch O rings according to customers' specific needs, including different materials (such as NBR rubber, silicone rubber, fluorine rubber, etc.)

Why use NBR to make 3-inch o-rings?

NBR has good oil resistance and can maintain good sealing performance when in contact with oily media such as petroleum, lubricating oil, and liquid fuel.

NBR has good wear resistance and can maintain a long service life under friction and extrusion forces. For larger size seals such as 3-inch O-rings, good wear resistance is required to ensure long-term reliable sealing.

For 3 inch O rings, the general operating temperature is usually between -40°C and +100°C, and NBR can meet the requirements of this temperature range.

NBR is an affordable sealing material, and its cost is lower compared to other high-performance rubber materials such as fluorine rubber (FKM) or silicone rubber (VMQ).
