Type O Spare Parts Product Line

O-rings are versatile sealing components used in key industries to ensure the efficient operation of equipment and prevent leaks and contamination.

Biomedical Device Valve Body

O-rings ensure the sterility and sealing of biomedical valve bodies, prevent contamination and leaks, and guarantee the precise operation of medical devices.

Sterile Pump

As a core component of aseptic pumps used in the food and pharmaceutical industries, O-rings must be chemically resistant, highly clean, and capable of preventing microbial contamination.

Mechanical Seal

O-rings are secondary components in mechanical shaft seals. They withstand high pressure and high temperatures, ensuring that rotating equipment remains leak-free, and are used in heavy machinery.

Material Selection for Type O Spare Parts

Selecting the right O-ring material is key to ensuring effective sealing and a long service life. Different operating environments, media characteristics, and temperature ranges all require corresponding material properties. Below are common O-ring materials and their recommended applications.

PI Polyimide

It offers excellent high-temperature resistance, with an operating temperature range typically between -200°C and +300°C. It possesses outstanding mechanical strength and chemical corrosion resistance, as well as good resistance to radiation.

PVDF (Polyvinylidene Fluoride)

It offers excellent chemical resistance (to acids, alkalis, and solvents) and high mechanical strength, with extremely low permeability to gases and liquids. Its operating temperature range is approximately -40°C to +150°C.

PEEK (Polyetheretherketone)

A high-performance thermoplastic material with exceptional mechanical properties, excellent chemical resistance (to hydrolysis and steam), and high wear resistance. The continuous operating temperature range is typically -60°C to +260°C.

PCTFE (Poly(chlorotrifluoroethylene))

It is known for its extremely low permeability to gases (especially water vapor), while also offering excellent chemical resistance and high compressive strength. Its operating temperature range is approximately -240°C to +200°C.

PTFE (Polytetrafluoroethylene)

Known for its extremely low coefficient of friction and virtually universal chemical resistance, it offers high-temperature resistance and excellent electrical insulation. Its operating temperature range is approximately -260°C to +260°C. It is widely used for seals and linings in the chemical, pharmaceutical, food, and semiconductor industries.

FFKM Perfluoroelastomer

Combining the chemical inertness of PTFE with the elasticity of fluorocarbon rubber, this material offers exceptional resistance to high temperatures and chemical corrosion. It operates within a temperature range of -25°C to +320°C. It is suitable for extremely demanding applications in the semiconductor, chemical processing, and oil and gas industries.

Wide-Ranging Applications of Type O Spare Parts

O-rings (outer rings) are among the most widely used sealing elements in industrial equipment. They can be found everywhere—from traditional manufacturing to high-tech industries, and from consumer appliances to heavy industrial machinery. Their reliable sealing performance and cost-effectiveness make them the sealing solution of choice across a wide range of industries.

Hydraulic and Pneumatic Systems

Seals in hydraulic cylinders, pneumatic cylinders, valves, and fittings are subjected to high pressure and frequent operation, requiring high-quality O-rings to ensure stable system operation and prevent fluid leaks.

Automotive and Transportation Industry

Seals in critical components such as the engine, transmission, braking system, and air conditioning ensure vehicle performance and safety. Resistance to oil and heat are basic requirements.

Semiconductor and Electronics Industry

Seals for vacuum equipment, chemical gas delivery systems, and precision process equipment require extremely high levels of cleanliness and airtightness, and therefore use O-rings made of special materials.

Food and Pharmaceutical Industries

Hygienic seals for processing equipment, filling machines, and conveyor lines must be made of food-grade materials that comply with FDA and health regulations to ensure product safety.

Petrochemical and Chemical Industries

Seals for reactors, pumps, piping, and storage tanks must withstand high temperatures, high pressures, and corrosive media; high-performance materials such as Viton are selected to ensure safety.

Water Treatment and Environmental Engineering

For seals used in wastewater treatment, pure water systems, and pumps and valves—which must withstand fluctuations in water quality and prolonged immersion—EPDM is a common choice.
