Seal Ring material for Hydraulic Quick Coupling

seal ring material for hydraulic quick couplings

Quick couplings are an important element used to connect at either end of a connection. Quick couplings are also known as quick connect couplers. Quick couplings are small yet incredibly durable and reliable to use, making them simple to connect and disconnect. They offer dependable fluid transmission for pneumatic, hydraulic, and vacuum systems, making them very reliable. A hydraulic quick coupling is specifically employed to attach or detach hydraulic hoses.

Quick Couplings offered by AKJia include:

  • Universal Quick Coupling
  • Agricultural Quick Coupling
  • Flat Face Quick Coupling
  • High-Pressure Quick Coupling
  • Dust Caps

Seal Ring Material used by AKJia for Hydraulic Quick Coupling

AKJia works toward the manufacturing and provision of top-quality hydraulic quick couplings. One of the main reasons for their superior quality is the selection of the right seal ring material according to the type of fluid being transmitted.

Here are the materials that AKJia uses:

NBR (Nitrile Rubber)

Buna-N O-rings made of nitrile rubber (NBR), which are resistant to petroleum-based fuels and lubricants, are one of the most widely used sealing elastomers. Copolymers of butadiene and acrylonitrile make up nitrile elastomers. Nitrile compounds come in several typical variants. While maintaining the same characteristics as the standard nitrile O-ring compound, nitrile O-rings can also be found in a metal-detecting type.

Generally, nitrile rubber can perform in temperatures between 40 and 226 degrees Fahrenheit (4.4 to 107.7 °C).

In addition to being caustic and aliphatic hydrocarbon resistant, NBR is three times more puncture resistant than natural rubber. It is, however, less adaptable. It is also less expensive than fluoroelastomers nitrile. A rubber variety called hydrogenated nitrile can maintain its heat and oxidation resistance while maintaining flexibility at lower temperatures. Applications involving oil resistance, high-temperature efficiency, and personal protection are all common uses for nitrile rubber.

FKM (Fluoroelastomer)

One of the most widely used seal ring materials, FKM, is a class of synthetic rubber made for very high-temperature operation. Exceptional levels of chemical, heat, and oil resistance are provided by FKM, which also has a usable service life of over 392 °F (200 °C). FKM is a family of fluoropolymer rubbers. The fluorine concentration of fluoroelastomers can be divided into three categories:

  • 66 percent
  • 68 percent
  • 70 percent

FKM rubber with a higher fluorine concentration will have increased fluid resistance as fluorine levels rise. O-rings, seals, and gaskets for a range of operations in the transportation, aerospace, power, and semiconductor industries are frequently made using FKM materials.

 

FFKM (Perfluroelastomer)

Poly(tetrafluoroethylene), or PTFE, is available in the form of perfluoro elastomers (FFKM). They are tetrafluoroethylene copolymers with perfluorinated ether, like perfluoro (methyl vinyl ether) (PMVE).

For applications requiring harsh chemicals at temperatures as high as 617 °F (325 °C), FFKM elastomers cover a critical gap. They offer exceptional high temperature and chemical resistance and are the most chemically inert elastomers on the market. Additionally, they have very low gas permeability and high resistance to weathering, ozone, and steam. Due to their extremely low compression set, they also have high durability for static and dynamic loads.
