Product details
This aftermarket TG4 pressure resistant oil seal measures 45mm inner diameter, 65mm outer diameter and 7mm in height, manufactured in blue NBR nitrile rubber. It features a corrugated outer diameter, triple-lip design with garter spring and an internal steel skeleton.
Importers, wholesalers and MRO buyers can submit RFQ with dimension, quantity, destination and working medium for a formal quotation.
Features & Benefits
The TG4 triple-lip design with short, rigid lip profile resists inversion under medium system pressure compared to standard double-lip seals.
Corrugated outer diameter resists seal rotation under vibration and accommodates thermal expansion between seal and housing.
Triple lip configuration: primary lip retains oil under pressure, secondary lip blocks dust and contaminants, and a third lip adds redundant sealing.
Blue NBR nitrile rubber offers good oil resistance and wear resistance, compatible with gear oils, engine oils and standard lubricants.
Internal steel skeleton with full rubber coating provides structural rigidity and reliable static sealing in the housing bore.
Standard 45x65x7mm dimensions match common TG4 housings used across engines, transmissions, rear axles and industrial equipment.
This is an aftermarket replacement seal. Always verify shaft diameter, housing bore, system pressure and application before ordering.
Factory standard options are available for marking and packaging; confirm all requirements on RFQ.
