They can withstand a variety of corrosive media to seal various parts well. Our seals are also noted for their particular functions. They can not only be used for the general sealing of parts but also can be used for sealing parts with the self-lubricating function.

A type – PTFE Single Lip Oil Seals

The A type is a rotary lip seal that features an ID lip that seals dynamically on a shaft and an elastomeric O-ring on its OD to seal statically in a bore. Since the lip is not spring energized, the radial lip contact forces are lower than a rotary metal lip seal, which allows […]

A type-Single Lip PTFE Stainless Steel Rotary Shaft Oil Seals

The PTFE lip seal is a rotary lip seal that features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. A gasket is sandwiched between layers of sealing lips and the can to seal off the potential leak path. Since the lip […]

AR/AL type-Ekonol filled PTFE Stainless Steel Thread Single Lip Oil Seals

The PTFE lip seal is a rotary lip seal that features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. A gasket is sandwiched between layers of sealing lips and the can to seal off the potential leak path. Since the lip […]

B type – PTFE Oil Seals With Good Performance

Double-lip, PTFE, rotary, shaft seal. The redundant seal lips enable this seal to handle higher pressure and create additional sealing capabilities, especially under flooded conditions. The soft OD eliminates damage to housings manufactured from expensive metals, and the integrated O-ring on the OD of the seal serves as an anti-rotation device and maximizes static […]

B type-Double Lip Stainless Steel PTFE Oil Seals

The PTFE lip seal is a rotary lip seal that features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. A gasket is sandwiched between layers of sealing lips and the can to seal off the potential leak path. Since the lip […]

BR/BL type-Stainless Steel Radial Shaft Thread Double Lip Oil Seal

The PTFE lip seal is a rotary lip seal that features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. A gasket is sandwiched between layers of sealing lips and the can to seal off the potential leak path. Since the lip […]

C type-Double lip Stainless Steel PTFE Rotary Oil Seals

The PTFE lip seal is a rotary lip seal that features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. A gasket is sandwiched between layers of sealing lips and the can to seal off the potential leak path. Since the lip […]

Custom Bronze filled PTFE Wear Strips/Guide tapes

DST is the wear ring or guidering of DSH Seals. The function of a hydraulic wear ring is to guide the shaft and hole sealing of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system. DST has a rectangular cross-section with rounded […]

DAH-Hydraulic double lips scraper seal PU

DAH wiper seal has a double lip seal with a dust lip and an oil seal lip. Its structure makes it excellent in dust resistance and less oil leakage. In addition, DAH lip wiper prevents dust, dirt, sand and metal chips from entering. Mainly used in hydraulic cylinders and cylinders. Axial movement of the hoist […]

DAI-Hydraulic single lip wiper seal PU

DAI is a single-acting elastomeric dirt wiper with bearing segments. Main and secondary seals, as well as the guidance of modern sealing systems, require reliable protection of the wiper. Dirt, dust, and moisture must not contaminate the working medium and, most importantly, must be kept away from the pressure seal edges. Depending on the application, […]

DAQ-PTFE Piston Hydraulic Compact X Ring

TA further development of the standard DAQ, the double-acting incorporates an elastomer. Quad ring seal and an elastomer or polyurethane Bean Seal in the dynamic sealing face. It is energized by two O-Rings to improve sealing behavior. DAQ commonly used in piston accumulators and medium-duty hydraulic cylinders. DSH Seals DAQ have a nitrile rubber (NBR) […]

DBH – Hydraulic Dust Seals Rubber Wiper Seals

DSH Seals has kept pace with the industry standards which expand to meet safety requirements. The dust rubber seals/wiper seals/dust seals and other sorts of seals in DSH Seals meet environmental standards’ requirements and industrial conditions. The wiper seal, also likewise referred to wipers, scraper ring, rubber seal, is a piston ring. It is also […]
