A piston seal is a part that is typically used in pneumatic, hydraulic, and mechanical equipment to provide a seal between the piston and the cylinder. Its primary purpose is to keep liquids or gases from seeping through the space between the cylinder and the piston. In order to guarantee appropriate system operation, piston seals are made to offer dependable sealing performance.
Piston seals are usually comprised of elastomeric materials such as rubber or polymer. Depending on the demands of the design and the many applications, they can have a variety of shapes and structures. O-shaped, square, V-shaped, and U-shaped piston seal shapes are frequently seen. To guarantee sealing contact, these sealing rings can be positioned in the cylinder’s grooves or on the piston.

The piston rod ring is a crucial component in the air suspension compressor pump, sealing and shielding the piston rod. It minimizes wear and damage caused by friction and keeps liquid or air from escaping, ensuring the pump’s proper operation. A number of standards, including ISO 9001, ISO/TS 16949, ASTM International Standards, and REACH, must be met by the rubber material used in the piston rod ring. The selection of materials is contingent upon factors such as chemical stability, sealing effectiveness, wear resistance, oil resistance, and resistance to high temperatures. The benefits of the piston rod ring include improved system efficiency, less wear and friction, chemical corrosion resistance, and sealing performance.

Informazioni di contatto
A typical sealing tool used in sealing applications between the piston and the cylinder to stop liquid or gas leaks is the piston seal.
There are numerous varieties of piston seals, such as O-ring seals, V-shaped seals, U-shaped seals, two-way seals, etc. To accommodate various application circumstances and sealing needs, each kind has a unique construction and operating principle.
O-ring closure
One of the most popular kinds of piston seals is the O-ring. It offers superior sealing performance in both static and dynamic applications thanks to its round cross-section. O-rings are simple to install and replace and come in a range of media and temperature ranges.
Shaped seal
With a U-shaped cross-section, the U-shaped seal can offer superior compression resistance and sealing performance. It is frequently employed to stop liquid or gas leaks in high-pressure pneumatic and hydraulic systems.
V-shaped seal
A V-shaped seal has a V-shaped cross-section and is also referred to as a V-ring or V-shaped packing. It is appropriate for sealing applications under high pressure and high temperature circumstances because of its broad sealing contact area and superior sealing performance.
Dual-phase sealing
Typically, bidirectional seals are made up of two symmetrical sealing parts that work together to simultaneously seal the piston on both sides. Applications like bi-directional hydraulic cylinders that need to be protected against piston leakage in both directions can employ this kind of seal.
Seal made of pneumatics
Piston seals made specifically for use in pneumatic systems are known as pneumatic seals. To handle higher working pressures and high-speed pneumatic movements, they typically employ unique materials and constructions.
Elastic materials with strong wear resistance, chemical corrosion resistance, and high temperature resistance, such as polytetrafluoroethylene (PTFE), nitrile rubber (NBR), and fluorine rubber (FKM), are typically used in piston seals. The right material selection is influenced by a number of variables, including the operating temperature, media, and sealing environment.
Excellent sealing materials with outstanding chemical, high temperature, and oil resistance include fluorine rubber (FKM) Viton. It is frequently employed in applications requiring high temperatures and chemical resistance for piston sealing.
Rubber Butadiene Nitrile (NBR) A popular and reasonably priced sealing material with good abrasion and oil resistance is nitrile butadiene rubber. It is appropriate for piston sealing in low- to medium-temperature environments as well as general industrial applications.
Rubber butyl (IIR)
One material that has good gas and liquid barrier qualities is butyl rubber. It is frequently utilized in piston sealing applications to stop liquid leaks and gas penetration.
PTFE, or polytetrafluoroethylene
PTFE is a temperature- and chemical-resistant substance with minimal friction. When corrosion resistance and high temperature sealing are necessary, it is frequently employed in piston sealing applications.
Poliuretano (PU)
Strong and resilient, polyurethane has excellent sealing qualities and is long-lasting. It works well in high-pressure hydraulic systems for piston sealing.
Rubber silicone (VMQ)
Silicone rubber is a great material for high temperature sealing and piston sealing in electronic equipment because of its exceptional electrical insulation and high temperature resistance.
One or more sealing rings, which can be mounted on the piston or in the seal seat, are typically found in piston seals. Sealing performance and durability are guaranteed by the sealing ring’s shape and structural design.
The structural designs of piston seals frequently change depending on the demands of a certain application and sealing performance standards. A thorough explanation of a few typical piston seal structures is provided below
Rubber silicone (VMQ)
Silicone rubber is a great material for high temperature sealing and piston sealing in electronic equipment because of its exceptional electrical insulation and high temperature resistance.
Single sealing ring
This is the simplest piston seal structure, consisting of a complete sealing ring. The sealing ring can be installed directly on the piston or in the seal seat, providing one-way or two-way sealing function.
Double body sealing ring
Double-body sealing rings consist of two half-rings and can be installed on the piston or in the seal seat. This structure can achieve better sealing effect and pressure resistance, and is suitable for high-pressure sealing applications.
Rubber-based sealing ring
Typically, elastomeric sealing rings are made of a metal spring with an elastic covering over it. To guarantee sealing performance, the spring applies pressure to bring the sealing ring and piston or sealing seat into close contact. Applications involving dynamic sealing and high-speed piston motion are appropriate for this construction.
Adhesive tape
A strip of seal that encircles the piston or is contained within the seal seat is called a sealing tape. Typically, it is composed of flexible materials that offer improved sealing performance and a greater sealing contact area.
Combined seals
rings, V-shaped seals, and U-shaped seals are a few examples of the various sealing elements that are combined to create composite seal structures. Depending on certain sealing needs, this structure can offer a more thorough sealing solution andworking conditions.
The primary purpose of a piston seal is to keep gas or liquid from leaking out while maintaining steady sealing performance. Sealing performance evaluation indicators include wear resistance, pressure resistance, and sealing efficiency.
In many different industrial domains, including automotive engines, pneumatic equipment, hydraulic cylinders, air cylinders, and hydraulic systems, piston seals are extensively utilized. Its primary duties are to guarantee the system’s regular operation and lower the possibility of leaks.
