Oil seal tc type， FKM oil seals (TC/TG4 types) provide high-temperature resistance (-20°C to 250°C), chemical durability, and reliable sealing for automotive/industrial machinery, with common sizes like ID 25-65mm, OD 40-65mm, and thickness 8-12mm. TG4 75*100*12.
The 2148F704 and 2148F701 are high-performance FKM oil seals designed for crankshaft applications, offering heat, oil, and chemical resistance. Popular models include1S4G6K301AA，12296-31U20, widely used in industrial and automotive systems for reliable sealing under extreme conditions.
High-Pressure TCN FKM Oil Seals are engineered for extreme conditions, combining fluorocarbon rubber's heat resistance (-20°C to 200°C), chemical compatibility, and high-pressure endurance (up to 0.98 MPa). Ideal for hydraulic pumps, industrial machinery, and automotive crankshafts, they feature a reinforced TCN design with a one-piece retainer to prevent deformation. Popular models include the NOK TCN series (e.g., AP2085G at 35×55×11mm and AP1338F at 25×45×11mm), along with common sizes like 22×42×11mm and 70×95×13mm.
The High Pressure TCV Oil Seal (FKM oil seal) Widely used in hydraulic systems, industrial pumps, and heavy machinery, it ensures reliable sealing in applications such as compressors and marine equipment. Common models include TCV-50x80x12 , 12mm width) and TCV-70x100x15 , which comply with rigorous testing standards like ISO 15848-1 for low leakage under thermal cycling. Customizable dimensions (ID: 20–150mm, OD: 40–180mm) are available to meet diverse industrial needs
Automotive oil seals (including HTCL and HTCR) are essential to prevent engine leakage, FKM oil seals can withstand high temperatures up to 250°C and have chemical durability, while key Toyota compatible models are very popular such as 90913-02112 (valve stem), 13719-1020 (crankshaft) and 20×40×10mm/105×130×12mm FKM seals ensure OEM-level performance, among which popular sizes such as 40×60×10mm and 5000289673 (wheel hub seal) are suitable for global automotive applications.
Wheel hub oil seals, automotive oil seals (TA, TB, TCY, TB5Y) ensure leak-proof performance for wheels, axles and drivetrains. FKM models can withstand temperatures from -20°C to 250°C and are resistant to oils/chemicals. Key models include TB5Y 43232-0T000 (80×101×9/10.2mm, Nissan), TCY/TB series such as TM 350 (104×146×25.5mm) for trucks, and FKM AP3527B (70×95×13mm). Common sizes: TB 62×82×9 (rear axle), 40×62×7mm (hydraulic pumps), and 85×145×12/37mm (heavy-duty systems). Universal options such as 5411401 meet a variety of industrial/automotive needs.
FKM Oil Seals provide superior resistance to extreme temperatures (-20°C to 250°C), oils, and chemicals, ideal for automotive, industrial, and hydraulic systems. Key models include 40×55×6mm (Toyota 90311-40022), HTCR 58×80×9mm (forklifts), and customizable sizes (ID 25–155mm, OD 40–90mm) for trucks and machinery. Popular variants like 40×65×10mm (single-lip shafts) and ATS 825.50×876.30×22.22mm (industrial pumps) ensure durability in engines, transmissions, and heavy-duty applications. OEM-compatible designs from brands like NOK and Toyota guarantee precision fitment.
TC oil seals (double lip radial seals with springs) are widely used in automotive and industrial fields, with standard configuration sizes of 14*22*7, 55*80*8, 55*82*8, 55*85*8, 55*90*10, 55*90*12 and 8*16*5, TG4 oil seals (three lip design with external threads) perform well in high pressure and polluted environments, with common sizes of 14*24*7, TG-65*95*12 and 40*80*12. 5000+ sizes
Research and Innovation
1. Material research and development and formula optimization
We focus on upgrading FKM materials, developing high temperature resistant (-20°C to 250°C) and corrosion resistant formulas, and expanding perfluoroether rubber (FFKM) technology to meet the needs of extreme working conditions such as automotive engines and semiconductor equipment, and significantly reduce high temperature compression deformation rate.
Structural design and process innovation
Innovative double-lip structure (such as TC/TG4 series) and metal skeleton reinforcement technology, combined with automated production lines to improve sealing efficiency and life, the product is adapted to high line speed scenarios (such as 35 m/s), replacing imported brand OEMs.
Customization and cross-industry applications
We provide full-size customization (ID 25–155mm), develop low-friction oil seals for new energy vehicles and high-pressure seals for engineering machinery (such as 85×145×12/37mm), strengthen simulation technology through industry-university-research cooperation, and cover the global automotive, energy and high-end manufacturing fields.
