Hydraulic seals, Piston Seals , Oil Seals Manufacturer Supplier for over 20 years .
The piston seal manufactured by DSH is used in hydraulic cylinders for fluid sealing. It can be located inside the cylinder head and seal the cylinder bore to prevent fluid flow through the cylinder head, which allows pressure to build up on one side of the piston, causing the cylinder to extend or retract.
The seal maintains a great sealing contact between the piston and the cylinder bore. The pressure differential caused by using our seal that acts on the piston to extend or retract the piston rod can effectively exceed 400 bar (5 800 psi). The pressure acting on the piston seal can increase the contact force between the piston seal and the cylinder surface. Moreover, our sealing surface has an anti-surface finish characteristic which is critical for proper sealing performance.
Our piston seals are usually divided into single acting (pressure acting on one side only) and a double acting (pressure acting on both sides) seals. It can even withstand pressure ≤60MPa. It has good physical and mechanical properties and high resilience. Its optional colors include black, green, brown, white, red, blue, gold, etc.
It can be used in a variety of media: hydraulic oil based on mineral oil, almost non-flammable hydraulic oil, water, air, etc. DSH seals promises a wide temperature range of -45 to +200℃ that is suitable for the seal.
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) […]
With five part designs, our KDAS compact seals are used as piston seals for double-acting cylinders with a maximum pressure of 35MPa. KDAS has an NBR ring with 3 sealing lips in the middle; Elastomer has an good sealing effect in both dynamic and static conditions.2 polyester elastomer back up rings to reduce the allowable […]
A double-acting O-Ring energized seal developed for sealing between two media such as fluid and gas. It incorporates a limited footprint quad-ring Seal inset into the dynamic sealing face. Installed in grooves. Applied to mobile hydraulics, holding cylinders, piston accumulators, etc. DQF combines the characteristics of low friction, high pressure, and high speed seals, […]
Gasket: Full name PTFE gasket, also called PTFE gasket or Teflon gasket on abroad, Flat gasket made of PTFE rods, tubes, plates machined or cut , V-shaped gaskets, piston rings, ball valve gaskets and other good features such as corrosion resistance, anti-aging and non-conductive. The back up ring is a plastic or rubber ring […]
The common compact seal SPGW is made of a sealing ring, an O-ring and back up ring. Sealing ring material is generally filled with PTFE; the O-ring is made of nitrile rubber (NBR). ) or fluororubber (FKM); the back up ring is made of polyoxymethylene (POM) material. The combined seal SPGW has good dynamic and […]
DSF is composed of PTFE seal ring and O-ring. It is used for double acting sealing of the piston rod of the hydraulic cylinder. Due to adopting special modified PTFE material, it can guarantee excellent low friction, wear resistance, extrusion resistance, high-temperature resistance and Chemical resistance. DSF is a very effective and reliable low friction […]
KZT is used in combination with piston seals and anti-wear rings. This product is used in combination with anti-wear and piston ring seals to prevent cylinder oil from mixing with foreign particles, resulting in seal damage and a long service life. The piston rod seal is used in combination with a metal bushing to prevent […]
An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. The O-ring […]
SPG is a compact double-acting piston seal for medium to heavy duty applications. The reinforced, thermally stable thermoplastic sealing surface with stepped joints allows the seal to pass through the port, making it ideal for double acting telescopic cylinders. It consists of a bronze-filled PTFE face ring preloaded by a square-section NBR ring. The cover […]
SPGO is a standard double acting seal. For reciprocated hydraulic system, allow large extrusion gap, has wide application, high static and dynamic sealing effect, be able to work in dusty condition, low friction, available in various of materials. Application SPGO Seals could use for the application of high pressure, low pressure double-acting […]
The common compact seal SPGW is made of a sealing ring, an O-ring and back up ring. Sealing ring material is generally filled with PTFE; the O-ring is made of nitrile rubber (NBR). ) or fluororubber (FKM); the back up ring is made of polyoxymethylene (POM) material. The combined seal SPGW has good dynamic and […]
U cup seal has a U-shaped cross-section and Y seal has a Y-shaped cross-section, and they are typical lip seals. Although U cup seal is a little bit different from Y seal in shape, they are often thought of the same sort of seal concerning their working principles. U cup seal, additionally named U cup […]
