Product details

This brand‑new aftermarket 85x135x8/19.5mm TC‑type differential oil seal is made of black NBR rubber and reinforced metal shell for stable press‑fit installation on automotive differential assembly. Double‑lip structure with garter spring maintains stable radial pressure on rotating shaft. It retains differential gear‑oil inside housing and stops dust, mud and splash‑water invading gear assembly. Suitable for auto repair shops, auto‑parts wholesalers and overseas bulk procurement. Core functions Gear‑oil retention: Prevent differential gear‑oil leakage under driving vibration and shock load Dust & mud exclusion: Resist sand, mud and splash‑water contamination for various road conditions Reinforced metal shell: Anti‑rust and reliable interference fit for differential housing bore Garter‑spring pre‑load: Consistent sealing performance under frequent vibration and temperature fluctuation

Material and process

Material ：Black NBR nitrile rubber sealing lip, anti‑rust painted carbon‑steel shell, stainless steel garter spring Structure ：TC‑type double‑lip rotary shaft oil seal Key properties ：Oil‑resistant, dust‑proof, vibration‑resistant, anti‑aging Working temperature:‑20℃ +120℃ Manufacturing features High‑temperature vulcanization bonding between rubber lip and metal shell, resist delamination under vehicle vibration. Precision‑ground sealing lip reduces friction heat and extends service‑life. Anti‑rust painted shell adapts to harsh automotive working environment. Black NBR compound compatible with automotive differential gear‑oil. Upgrade option ：FKM fluoro‑rubber version for higher‑temperature working environment.

Application and compatibility

Product Type ：TC‑type differential oil seal for automobile Key dimension ：ID85mm × OD135mm × dual width8/19.5mm Compatible media ：Automotive differential gear‑oil. Working conditions: Automotive differential shaft, withstand vehicle vibration, mud and splash‑water. Not suitable for ：Strong corrosive solvents, extreme ultra‑high‑temperature special‑purpose equipment. Fit applications ：Aftermarket replacement seal for automotive differential repair. Buyer reminder ：This is aftermarket replacement part. Please verify shaft diameter and housing bore before placing order. Mismatch dimension will cause gear‑oil leakage after installation.

Selection guide

Selection Tips 1. Confirm dimension ID85mm, OD135mm, dual width8/19.5mm and seal type TC differential seal. 2. Standard black NBR for regular gear‑oil environment; select FKM upgrade for high‑temperature scenarios. 3. Inspect shaft and differential housing bore before installation; repair shaft wear, rust and burrs. Damaged mating surfaces will lead to early leakage. Installation Steps Preparation Clean differential housing bore and shaft surface thoroughly, remove old seal residue, oil dirt and metal burrs. Pre‑lubrication Coat sealing lip and shaft surface with matching differential gear‑oil. Dry installation is strictly forbidden; dry friction will damage sealing lip. Orientation Confirmation Main sealing lip faces gear‑oil cavity; dust lip faces outward. Wrong installation direction causes gear‑oil leakage and loses dust‑proof function. Vertical Press‑fit Use proper press‑sleeve tool to press oil‑seal evenly and vertically. Never strike rubber lip directly to avoid shell deformation and lip tearing. Seating Inspection Ensure oil‑seal sits fully flush inside housing bore without tilt. Visual Check Inspect sealing lip for tears and shell deformation. Tiny invisible damage triggers seepage after commissioning. Rotation Test Manually rotate shaft assembly to confirm smooth movement without abnormal binding resistance.

Packaging and delivery

Inner package ：Individual anti‑dust poly bag for each unit to protect sealing lip from scratch. Outer package ：Reinforced export carton. Packing quantity ：Adjustable per order requirement. MOQ ：No MOQ for stock items, sample order acceptable. Lead‑time ：Stock items ship within 3‑5 working days; custom logo and export‑packaging orders 30‑45 working days. Custom options ：Custom logo printing available, custom order MOQ≥1000 pcs. Shipping protection: Moisture‑proof, dust‑proof and compression‑resistant packing to prevent seal deformation during transit.
