WALFORM Ring

     WALFORM technology consists of 3 parts: 24-degree cone fitting, designed nut and sealing ring. The standardzed pipe ends are connected by DIN standard joints and nuts. The sealing devices are installed on possible leakage point. The joint complies with DIN 2353 and ISO8434-1 standards. Its characteristics include high pressure level resistant, leak-proof, reliable pipe fixing, easy installation and high dynamic bearing capacity. Through the steel pipe forming equipment, the steel pipe is cold-extruded and reshaped, so that the deformation of the steel pipe is uniform. This will make quality control easy and reliable while there is no pitting and cracks.
     The following are the detailed dimension table we provide for WALFORM ring. More various dimensions and information are avaliable on our catalog.

PTFE

​       ​The advantages of PTFE coating include easy identification, easy assembly, low friction, and non-sticky. The PTFE coating is a dry film that reduces the friction on the surface of the seal and therefore no fluid lubricants are needed. PTFE coating also provides advantages for the assembly lines. We are here to supply qualified and reliable sealing coating to effectively reduce the friction coefficient.

DIN 3869 Profile Ring

       ​DIN 3869 profile ring is one of the many seals for industrial use. It can be used as a special seal for pneumatic and hydraulic joints such as pipe joints, hydraulic plugs, and transition joints, with better sealing effects than traditional O-rings. This elastomer seal can be applied to threaded ports and screw ends as an axial static seal. There is hardly any change with the cross-section under high pressure.
       The following are the detailed dimension table we provide for DIN 3869 profile ring. More various dimensions and information are avaliable on our catalog.

Bonded Oil Washer

​        Bonded seal are suitable for oil-based pipeline systems, providing seal for pressure systems including welding, ferrule joints, expansion pipe joints, screw plugs and mechanical devices, to prevent leakage of oil, fuel, water and medicine. Due to its simple structure, high sealing effects and low price, bonded seals are widely used in machinery manufacturing.
       The following are the detailed dimension table we provide for boned oil sealing washer. More various dimensions and information are avaliable on our catalog.

Skeleton Oil Seal

​       Rotary oil seals (oil seal, skeleton oil seal, rotary shaft lip seal ring) are standard contact seals, consisting of rubber elastomer, metal spring and other components.
     They are mainly used to prevent the leakage of liquid (lubricating oil) from the rotating shaft and oil seal housing, and also to prevent dust, dirt, water and other impurities from infiltrating and polluting the oil, which will affect the life of the whole mechanism.
      The following are the detailed dimension table we provide. More various dimensions and information are avaliable on our catalog.

Back Up Ring

​       The main function of the back up ring is to prevent the O-ring from being squeezed onto the low-pressure side under the action of pressure when the O-ring gap is large, in which the O-ring may be damaged and consequently lose its function if there is excessive pressure.
      The following are the detailed dimension table we provide. More various dimensions and information are avaliable on our catalog.

Applications:

Temperature:               -30°C to 120°
CExposure to liquids:    Refer to the chemical resistance table.
Pressure resistance:   See chart in the followings (in the chart: horizontal coordinate: total diameter gap (mm)
Vertical coordinate:     Operating pressure (bar); curve labeling (from top to bottom);  Limits for NBR back-up rings; limits for PTFE
                                       back-up rings. O-ring hardness will also affect its use.

RAREFLON Back Up Ring

      RAREFLON series back up rings are the ptfe coated back up rings. It combines the advantages of PTFE and NBR and could prevent the O-ring from being squeezed onto the low-pressure side under the action of pressure when the O-ring gap is large, in which the O-ring may be damaged and consequently lose its function if there is excessive pressure. To compare with the normal back up ring, RAREFLON back up ring has a broader area of applications.
      The following are the detailed dimension table we provide for RAREFLON back up rings. More various dimensions and information are avaliable on our catalog.
