Product details
This aftermarket replacement TG outer‑rib double‑lip oil seal is dimensioned 85×115×12 mm, brown NBR nitrile rubber, metal‑cased construction with circumferential external ribs on outer diameter. TG rib‑shell structure greatly increases static friction inside housing bore, effectively prevents seal spinning caused by vehicle vibration and thermal expansion, especially suitable for automotive aluminum alloy housing assemblies.
Built‑in garter spring and double‑lip configuration: primary sealing lip retains gear oil / lubricant, secondary dust lip blocks mud, water, grit and road contaminants. This metric standard TG‑size is widely applied for automotive rear axle, differential, transmission output shaft and general industrial reducers. No universal public OE cross‑reference number for this standard dimension, applied as aftermarket replacement seal for matching‑size vehicle assemblies.
Targeted at automotive spare‑parts importers, wholesalers and vehicle repair workshops.
