　　Hydraulic oil seal components are used to prevent leakage of hydraulic fluids from cylinders and to protect the system from dust and dirt. Hydraulic oil seal components are subject to high pressure, extreme temperature and lateral forces in the cylinder. Therefore, they need to have certain basic performance to ensure their functionality and durability. In this article, we will introduce some of the basic performance of hydraulic oil seal components.

　　Mechanical and Physical Properties

　　Hydraulic oil seal components should have certain mechanical and physical properties, such as tensile strength, elongation at break, hardness and compression set. These properties affect the ability of the seal components to resist deformation, rupture and wear under stress. Generally, hydraulic oil seal components should have high tensile strength, moderate elongation at break, appropriate hardness and low compression set.

　　Elasticity and Resilience

　　Hydraulic oil seal components should have sufficient elasticity and resilience to adapt to the changes of shape and size of the sealing surfaces. Elasticity is the ability of the seal components to return to their original shape after being deformed by external forces. Resilience is the ability of the seal components to absorb and release energy during deformation. Generally, hydraulic oil seal components should have high elasticity and resilience to maintain good sealing performance.

　　Heat Resistance and Low Temperature Flexibility

　　Hydraulic oil seal components should have good heat resistance and low temperature flexibility to withstand the temperature range of the operating environment. Heat resistance is the ability of the seal components to resist thermal degradation and softening at high temperatures. Low temperature flexibility is the ability of the seal components to resist hardening and cracking at low temperatures. Generally, hydraulic oil seal components should have high heat resistance and low temperature flexibility to prevent failure or leakage due to temperature changes.

　　Chemical Compatibility

　　Hydraulic oil seal components should have good chemical compatibility with the hydraulic fluids and other substances in the operating environment. Chemical compatibility is the ability of the seal components to resist chemical attack and swelling by hydraulic fluids and other substances. Generally, hydraulic oil seal components should have good chemical compatibility with mineral oils, synthetic oils, water-based fluids, ozone and ultraviolet rays.

　　Wear Resistance and Friction Coefficient

　　Hydraulic oil seal components should have good wear resistance and friction coefficient to reduce friction and wear between the seal components and the hardware. Wear resistance is the ability of the seal components to resist abrasion and erosion by hydraulic fluids and solid particles in the operating environment. Friction coefficient is the ratio of friction force to normal force between two surfaces in contact. Generally, hydraulic oil seal components should have high wear resistance and low friction coefficient to extend their service life and improve their efficiency.
