Product Description

O-ring application introduction

Main uses: electrical appliances, automobile and motorcycle parts, cylinders, hydraulic presses, oil pumps, sanitary ware, bearings, antenna waterproofing, lighters, etc. require sealing materials with anti-friction properties, oil resistance, non-polar solvents, good air tightness, etc. It is used in aliphatic hydrocarbons (propane, ethane, mineral oil and grease, fuel oil), vegetable oils and animal oils, silicone oils, silicone greases, chemical fire extinguishing agents, acid-base salt solutions diluted at low temperatures, and media below 120 °C.

Rubber is a professional manufacturer and supplier of rubber products such as O-rings (O-rings), waterproof rings, rubber rings, flat washers, sealing rings, sealing strips, skeleton oil seals, hard-wearing belts, guide belts, etc. Products can enjoy the following product advantages and professional services:


1. Product advantage

1). Good surface gloss

2). Excellent resilience performance

3) Excellent sealing effect

4). Excellent weather resistance

5). Material stability is good

6). Customizable non-standard models

7). Complete model, standing stock

8) Mature technology and stable quality

9). International CNAS laboratory has domestic advanced rubber and lining performance testing equipment and instruments. Testing capabilities cover relevant national and industry standards and US ASTM standards, and environmental protection

10). Meeting the needs of sustainable development


O-ring sealing performance is excellent, working life is high, dynamic pressure sealing working life is 5-10 times higher than conventional rubber sealing products, up to dozens of times.

The O-ring has low frictional resistance and equal dynamic and static friction. It is 1/2-1/4 of the friction of the "0"-shaped rubber ring, which can eliminate the "crawling" phenomenon of low-speed and low-pressure movement.

The O-ring is highly wear-resistant and has an automatic elastic compensation function after the sealing surface is worn.

O-ring has good self-lubricating properties. Can be used as an oil-free lubrication seal.

The O-ring has a simple structure and is easy to install.

O-ring working pressure: 0-300MPa; working speed: ≤15m/s; working temperature: -55-250 degrees.

O-ring suitable medium: hydraulic oil, gas, water, mud, crude oil, emulsion, water-ethylene glycol.
