OKC oil seals, crafted from premium rubber, deliver reliable sealing for hydraulic and pneumatic systems. Their robust design ensures excellent leakage prevention, enhancing equipment efficiency and durability across industrial applications.
OUY Hydraulic Seal is a high-quality oil seal for heavy industry and machinery, serving as a core component for excavators with excellent sealing and durability. It offers wear/corrosion resistance, high-pressure adaptability, and multi-scenario sealing (piston/dust-proof). It reliably supports long-term operation of construction excavators and general machinery hydraulic systems.
Designed specifically for hydraulic cylinders, the IDI-style piston rod seal made of polyurethane delivers robust sealing performance—its U-shaped structure with dual-lip design forms a strong barrier against leaks, while compatibility with backup rings prevents extrusion, making it suitable for heavy-duty scenarios.
The TG4 skeleton oil seal is an advanced sealing solution featuring external circular threads and 3 built-in lips, delivering superior anti-leakage (both internal and external) and dust-proof performance, widely suitable for industrial machinery, automotive systems, and hydraulic equipment.
Engineered for automotive, manufacturing, and heavy-duty industrial machinery, this Rotary Seal ROI features a low friction coefficient and durable PU construction, effectively preventing fluid or gas leakage in high-pressure rotating applications while boasting an extended service life.
The Pneumatic Sealing DK Buffer-Type Integral Piston integrates sealing and guiding functions, featuring a double U-seal and metal skeleton bonded structure. It is rubber-coated for corrosion resistance, compatible with oil-lubricated and initially lubricated oil-free air, and operates smoothly with low friction.
The HBY combined buffer polyurethane seal ring is a high-performance sealing solution tailored for construction machinery and hydraulic equipment, integrating a polyurethane seal ring with POM/PA backup rings to deliver exceptional pressure resistance (up to 50MPa) and wear resistance.
This high-performance COMBI combination oil seal features a polyurethane (PU) dust lip, delivering exceptional resistance to external contaminants like dust, dirt, and debris while reliably preventing internal oil leakage, making it ideal for harsh working environments.
Engineered for heavy-duty applications like axle hubs and drive shafts, this all-in-one Cassette Oil Seal eliminates the need for hardened/ground shaft surfaces, reduces maintenance costs, and effectively blocks mud, dust, and contaminants while ensuring long service life.
The GSZ Combined Dust Seal features a high-performance BRONZE FILLED PTFE sealing ring, delivering exceptional wear resistance, thermal conductivity, and dust-scraping efficiency—ideal for hydraulic, pneumatic systems, and servo equipment operating in severe dust or low-temperature environments.
Designed for high-pressure, heavy-load reciprocating hydraulic systems (e.g., bulldozers, forging presses), the GSJ-W Steck seal combines a durable bronze-filled PTFE sealing element with NBR/FKM/PU elastomers, ensuring low friction, stable sealing, and long service life.
The heavy-duty bore Glyd Ring GSF-W is a high-performance hydraulic piston seal, featuring a filled PTFE main ring paired with optional NBR, FKM, or PU O-rings to deliver excellent dynamic/static sealing, low friction, and resistance to high pressure, making it ideal for heavy machinery like injection molding machines and construction equipment.
