45 Degree Mold Line O-Ring for special working conditions

Hardness: Shore hardness 25-95 degrees

Suitable temperature range: -80 ℃ to 300 ℃, different materials may vary

Good sealing performance: The angle between the parting surface of the 45 degree mold line O-ring and the circumferential plane is 45 degrees. Common O-rings are mostly horizontal mold lines, and the mold line is exactly on the inner and outer diameters. If used in dynamic sealing, the inner and outer diameters are exactly on the working surface, and the burrs of the mold line will affect the sealing effect. Therefore, for dynamic sealing, a 45 degree mold opening O-ring will be selected, and the mold line is not on the main sealing surface of the O-ring, avoiding the impact of mold line burrs on sealing performance. The produced O-ring has a smooth working surface, ensuring the accuracy of the maximum outer diameter position and minimum inner diameter position of the O-ring, improving the sealing effect, extending the service life, and sealing performance. Excellent, it can effectively prevent liquid or gas leakage.

High precision: The 45 degree mold line can ensure the accuracy of the maximum outer diameter position and minimum inner diameter position of the O-ring, thereby improving the sealing effect and extending the service life.

Application scenarios

Hydraulic systems
01
Between the piston and the cylinder barrel of a hydraulic cylinder, the 45-degree parting line O-ring can prevent the leakage of hydraulic oil, ensuring the pressure stability of the hydraulic system and the energy transfer efficiency. At the connection parts of hydraulic pipelines, it can play a good sealing role and prevent oil leakage.
Pneumatic systems
02
Used for the sealing of pneumatic components such as air cylinders and air valves, ensuring the sealing of compressed air, enabling the pneumatic system to work properly and achieving precise motion control. The 45-degree parting line rubber ring for the piston of an air cylinder has good elasticity and sealing performance, and can effectively prevent gas leakage. It has good abrasion resistance and can withstand the friction of the reciprocating motion of the piston. The general temperature resistance is around -30°C to 100°C. It is suitable for the sealing of various air cylinder pistons, and its function is to ensure the pressure stability of the air cylinder, make the piston move smoothly, and improve the working efficiency and reliability of the air cylinder.
Automotive engines
03
In parts such as the piston ring groove and valve stem seals of the engine, the 45-degree parting line O-ring can prevent the leakage of engine oil and the intrusion of combustion gas into the crankcase, ensuring the normal lubrication and combustion process of the engine.
Aerospace field
04
The fuel systems, hydraulic systems, and various sealing parts of aircraft have extremely high requirements for sealing. Relying on its high precision and good sealing performance, the 45-degree parting line O-ring can ensure flight safety and the reliable operation of equipment.
Other mechanical seals
05
At the sealing parts of various mechanical components with rotating or reciprocating motions, such as pumps, compressors, and reducers, it can adapt to different working conditions, reduce the risk of leakage, and improve the stability and reliability of the equipment.
