Product Description

Product Description

Product Overview

An o ring is a circular elastomer sealing ring designed to prevent the leakage of liquids or gases in static or dynamic applications. It is one of the most widely used and reliable sealing components in industrial machinery, automotive systems, hydraulic equipment, and general engineering.

O-Ring Key Features

High sealing performance: Provides stable sealing under pressure, vacuum, and various media.

Wide material options: Available in NBR, FKM, EPDM, Silicone, HNBR, PTFE-coated, etc., to match different working conditions.

Excellent elasticity & compression set resistance: Ensures long-term sealing without deformation.

Chemical & temperature resistance: Suitable for oils, fuels, water, air, solvents, and high/low-temperature environments.

Standardized sizes: Complies with AS568, ISO 3601, JIS B 2401, DIN 3771, ensuring global compatibility.

Easy installation: Simple structure, low cost, and high sealing reliability.
