O-type sealing strip
O-type sealing strip is a kind of annular sealing material, usually made of rubber, silicone or fluororubber, with a circular cross section. It has good sealing performance and elasticity, and can be used to fill or seal the joints of pipes, bearings, valves and other equipment to prevent liquid or gas leakage. O-type sealing strip is widely used in machinery, automobiles, aerospace and other fields.
specification
Material: Common materials include nitrile rubber (NBR) fluororubber (FKM) silicone (VMQ) etc.
Size: Usually specified by diameter and cross-sectional thickness but can be customized to meet specific needs.
Cross-sectional shape: round
Color: usually black gray white etc. can also be customized according to customer needs.
The quality control of O-type sealing strips usually includes raw material inspection, production process control, finished product inspection and performance testing. Through strict quality control, ensure that the sealing strips have good sealing performance, durability and stability.
O-type sealing strips are widely used in the following fields:
Mechanical equipment: used to fill or seal the joints of pipes, bearings, valves and other equipment to prevent liquid or gas leakage.
Automotive industry: used for sealing of automobile engines, transmission systems and other parts to ensure the normal operation of various parts of the car.
Aerospace: used for sealing of aircraft engines, hydraulic systems and other parts to ensure the safe operation of aircraft.
Clean the installation surface: ensure that the installation surface is clean, dry, free of oil and dust.
Apply lubricant: Before installing the O-type sealing strip, you can apply lubricant appropriately to reduce friction and facilitate installation.
Appropriate heating: For O-type sealing strips with higher hardness, you can heat them appropriately before installation to increase their softness and facilitate installation.
Storage: O-type sealing strips should be stored in a cool, dry and ventilated place, away from direct sunlight and high temperature environment.
Avoid contact with chemicals: Avoid long-term contact of O-type sealing strips with oils, solvents and other chemicals to avoid affecting their performance.
Packing and transportation methods:
Packaging: Usually plastic bags, cartons or boxes are used to protect the sealing strips from contamination or damage.
Transportation: Transportation by land, sea or air to ensure that the product is not damaged during transportation.
1. How to choose the right material for O-type sealing strips?
- The choice of material should be determined according to the specific working environment and requirements. For example, NBR is suitable for general industrial occasions, FKM is suitable for high temperature and chemically corrosive environments, and silicone is suitable for high temperature and food-grade applications.
2. What is the temperature resistance range of O-type sealing strips?
- The temperature resistance range of O-type sealing strips of different materials is slightly different, usually between -40°C and +200°C.
3. How to check the sealing effect of the O-type sealing strip after installation?
- After installation, you can check the sealing effect by applying some water or oil to the sealing part and observing whether there is leakage.
4. Can the O-type sealing strip be reused?
- Generally, the O-type sealing strip can be reused, but when disassembling and reinstalling, you should carefully check whether there is any damage on its surface to ensure the sealing effect.
