Description of PTFE seal
The Spring Energized PTFE Seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE (or other polymer) seal partially encapsulating a corrosion-resistant metal spring energizer. The PTFE jackets are precisely machined, filled with PTFE composites and other high performance polymers, function at temperatures ranging from cryogenic to 250 C and inert to almost all chemicals. Some types also can be used in sanitary environment. Seals are available with a variety of spring energizers, each having characteristics to meet specific requirements. Spring loading can be adjusted to meet critical low or extremely high requirements in dynamic applications.
Radial Seals in Static Service. Radial Seals in Reciprocating Motion. Radial Seals in Rotary Motion. Inside face Seals in Static and rotary Service. Outside face Seals in Static and rotary Service.
Section structure Symmetric, for Rod, for Piston are available.
Spring type: U shaped spring(Type 400) Round wire spring (Type APS) O shaped spring (Type 103)
Groove Standard Heel Groove. Extended Heel Groove Flanged Heel Groove.
Size Both imperial and metric sizes are available on all types.

Some of our factory's rubber seal

Step Seal           Step seal is usually made from synthetic rubber qualitative protection ring and filled ptfe qualitative special shape of rectangular, trapezoidal seal ring, like to circle can be divided into the hole with the step seal and with the stern shaft sealing, the sealing effect and the sealing mechanism and to circle, but it only has a one-way seal effect.   Conventional materials: PTFE/ NBR/ PU;   Temperature: -30/+100 degrees Celsius;   Speed: Less than 5m/s;   Pressure: Less than 40Mpa	SPGO         SPGO is usually made from synthetic rubber qualitative protection ring and superposition of filled ptfe qualitative square seals use, it can be divided into the hole and shaft used to use to circle, but its sealing function is the same, in accordance with its own initial deformation on the sealing surface of high contact stress, prevent leakage of pressure of the liquid. Hydraulic cylinder, pressure of liquid by elastic ring in the maximum extrusion rectangular sealing ring, make it close to the sealing surfaces, resulting in increased with the pressure of the liquid pressure of higher and higher additional contact stress, contact stress and the initial together to prevent leakage of liquid pressure. Conventional materials: PTFE/ NBR/ PU; Temperature: -30/+100 degrees Celsius; Speed: Less than 5m/s; Pressure: Less than 40Mpa
Piston seal           Piston seal used for reciprocating motion of hydraulic cylinder.   Conventional materials: TPU / CPU/ Rubber;   Temperature:   TPU: -40/+80 degrees Celsius; GPU: -40/+120 degrees Celsius;   Speed: Less than 0.5m/s;   Pressure: Less than 32Mpa;	Rod seal           Rod seal used for reciprocating motion of hydraulic cylinder.   Conventional materials: TPU / CPU/ Rubber;   Temperature:   TPU: -40/+80 degrees Celsius; GPU: -40/+120 degrees Celsius;   Speed: Less than 0.5m/s;   Pressure: Less than 32Mpa;
Stainless steel lip Oil Seal           Stainless steel lip oil seal is made of stainless steel plate, the shell can be rubber or plastic bags, lip with modified PTFE, wall engraved with the spiral groove, it has wide contact with shaft surface, a thrust inward happens when axis rotation, stop the outflow of fluid and achieve effective seal. Skeleton oil seal seal selection of materials for the filled PTFE modified (main filling ingredients for: glass fiber, carbon fiber, graphite, molybdenum disulfide) greatly improve the wear ability of PTFE. Temperature range -70 °C to 250 °C, pressure of 3 mpa, suitable for all kinds of brands, various types of screw, sliding vane compressor is used. Conventional materials: PTFE+SS	Wiper           Wiper used for reciprocating motion cylinder, cylinder piston rod sealing and dustproof.   Conventional materials: TPU / CPU/ FKM/ NBR   Temperature:   TPU: -40/+80 degrees Celsius; GPU: -40/+120 degrees Celsius; NBR: -30/+120 degrees Celsius; FKM: -20/+200 degrees Celsius;   Speed: Less than 0.5m/s;
V-packing   v-packing are axial seals with an elastomer sealing element vulcanised in the mould. The typical design of a v-packing is comprised of the body, the flexible joint and the sealing lip. It is consist of three parts, which are seal ring, support ring and pressing ring. It is the seal used for piston rod of tank. Conventional materials: NBR, NBR Fabric, Viton, Viton fabric, PTFE, PTFE filled carbon/bronze, PU, PA, copper Temperature: NBR: -30°C /120°C; FKM -20°C /200°C; PTFE: -55  °C  /260 °C Speed: Less than 5m/s; Pressure: Less than 60Mpa	TC oil seal   Application:   1. Fluid system (static& dynamic) 2. Hydraulic system (dynamic) 3. Pneumatic system (dynamic) 4. Oil or grease media sealing  5. Water media sealing 6. automobile, motorcycle, industry,  agricultural machinery, truck, buses, trailers, exercise equipment.   Conventional materials: NBR/ FKM
