Valve Stem Oil Seal
Miniature special seals for engine valve stems, preventing engine oil from entering combustion chambers; available in standard rubber and high-temperature FKM fluoroelastomer versions.
Crankshaft Oil Seal (Front Crankshaft Seal / Rear Crankshaft Seal)
Large-size double-lip dustproof seals installed at both ends of crankshafts, resistant to high-temperature engine oil, mostly made of FKM fluoroelastomer.
Camshaft Oil Seal
Small skeleton seals for camshaft ends, sealing the camshaft lubrication cavity.
Water Pump Seal (Water Pump Oil Seal)
Specially designed to seal coolant and antifreeze, mainly made of EPDM ethylene propylene diene monomer, resistant to water without swelling, different from standard oil seals for lubricants.
Turbocharger Oil Seal
High-temperature resistant fluoroelastomer seals for turbochargers, tolerant of high-temperature oil gas and high-speed rotating shafts.
Axle Shaft Oil Seal
Seals for left and right axle housings of vehicles, preventing transmission fluid leakage with outdoor dust and water resistance.
Differential Oil Seal
Shaft seals for input and output ends of rear differentials, widely used in trucks and SUVs.
Transmission Input / Output Shaft Oil Seal
Special seals for manual and automatic transmissions, compatible with high-temperature gear oil, mostly made of ACM acrylate rubber.
Drive Shaft Oil Seal
Seals for drive shafts of trucks and agricultural machinery, resisting splashing mud and water.
VC Multi-Lip Wheel Hub Oil Seal
Wide-profile multi-lip seals for wheel hubs of trucks, loaders and excavators, blocking heavy mud, sand and water.
Floating Oil Seal (Floating Seal Ring)
Combination of paired metal rings and O-rings, used for travel motors and reducers of excavators, heavy-duty sealing for dusty working conditions.
Drum Wheel Reducer Oil Seal
Wide-body seals for wheel-side reducers of heavy construction vehicles and tractors.
TC Double-Lip Inner Skeleton Oil Seal (Most widely used universal type)
Metal skeleton wrapped inside rubber; one primary sealing lip for oil retention + one secondary lip for dustproofing, general fit for motors, gearboxes and water pumps.
SC Single-Lip Inner Skeleton Oil Seal
Only one sealing lip without dustproof function, applied to small indoor motors with clean working environments.
TB Double-Lip Outer Skeleton Oil Seal
Exposed metal outer skeleton with tight interference fit and good heat dissipation, for heavy-duty reducers.
SB Single-Lip Outer Skeleton Oil Seal
For low-speed heavy equipment under clean conditions.
Skeletonless Flexible Oil Seal
No metal supporting frame, high flexibility, suitable for eccentric shafts and irregular cavities.
High-Pressure Reinforced Oil Seal
Thickened supporting lip structure for oil pumps and hydraulic motors, preventing lip bulging and oil leakage under internal hydraulic pressure.
Recirculation Groove Oil Seal (TCV / TC4 Type)
Spiral recirculation grooves on sealing lips, pumping leaked oil back into housing during high-speed rotation, anti-leak solution for high-speed spindles and motors.
PTFE Oil Seal (Polytetrafluoroethylene Seal)
Ultra-wear resistant and chemical corrosion resistant, designed for ultra-high rotating speeds, applied to chemical pumps, air compressors and hydraulic pumps.
Valve Oil Seal (the style you mentioned)
Rotary/reciprocating shaft seals for valve stems, divided into skeleton and skeletonless types, sealing lubricants or media; categorized into domestic water valve seals and industrial gas/oil valve seals.
Miniature Oil Seals for Power Tools
Small TC/SC size seals for angle grinders, electric drills and other power tools.
Air Compressor Oil Seal
Special seals for air conditioners and air compressors, resistant to refrigerants and high temperatures.
Flanged Oil Seal
Integrated flange on outer diameter, directly bolted to end caps for easy positioning, used for large reducers and box end covers.
End Cap Oil Seal (Blind Cover Seal)
Integrated sealing for stationary end caps with penetrating rotating shafts, replacing separate end cap + seal assemblies.
Multi-Lip Compound Dustproof Oil Seal
3-lip or 4-lip structures for mines, harvesters and agricultural machinery under heavy dust and mud conditions.
Eccentricity Compensating Oil Seal
Wide flexible lips to accommodate shafts with large runout and eccentricity.
Split Assembled Oil Seal
Splittable design for easy installation on extra-large diameter heavy equipment, such as large rollers and steel mill machinery.
