Product details

This 56x112x8/10 mm shaft oil seal cross‑references OEM number 4K14681. Constructed from brown NBR nitrile rubber with built‑in metal shell and garter spring, it is a dedicated sealing component for automotive repair. The oil seal provides sealing for rotating shafts to prevent lubricant leakage, while blocking dust, mud and contaminants from entering the housing. It protects internal bearings and transmission components and reduces equipment failure risk. Brand‑new high‑quality aftermarket replacement manufactured to match OEM specifications, direct replacement for part 4K14681. Ideal for auto repair shops, auto‑parts wholesalers and overseas aftermarket bulk procurement. Core functions Oil retention ：Effectively stop lubricant leakage and maintain proper internal lubrication Dust protection ：Block dust and mud from penetrating mechanical assemblies Reinforced shell ：Metal shell maintains seal shape and resists deformation during installation Garter spring preload: Spring keeps consistent contact against shaft surface for long‑term sealing performance

Material and process

Material ：Brown NBR nitrile rubber, carbon steel metal shell, stainless steel garter spring Structure ：Radial double‑lip shaft oil seal Key properties ：Mineral oil resistance, wear resistance, anti‑aging Working temperature:‑20℃ +120℃ Manufacturing features High‑temperature vulcanization bonding: Rubber firmly bonded to metal shell to avoid delamination. Precisely machined sealing lip to minimize shaft friction and extend service life. Anti‑rust treated metal shell for improved storage performance under humid conditions. Brown NBR compound compatible with automotive mineral‑based lubricants, resist swelling and hardening. NBR material advantages Good compatibility with engine oil and gear oil, stable performance under general automotive operating conditions. Excellent wear resistance for continuous rotating‑shaft operation. Cost‑effective for large‑volume aftermarket repair purchases. FKM fluoroelastomer upgrade available for higher‑temperature working scenarios.

Application and compatibility

Product Type ：Aftermarket radial double‑lip shaft oil seal for automotive repair Key dimension ：ID 56mm × OD 112mm × Width 8/10mm OEM Cross‑reference No.: 4K14681 Typical application: Automotive transmission, gearbox and axle repair matching OEM 4K14681. Compatible media ：Engine oil, gear oil, grease. Working conditions: General automotive medium‑pressure ambient‑temperature service, resist dust and splash mud. Not suitable for ：Strong corrosive solvents, extreme high‑temperature special‑purpose equipment. Buyer reminder ：This is aftermarket replacement part. Please verify dimension and OEM number before ordering, double‑check shaft and housing bore dimension to avoid sealing failure caused by mismatching.

Selection guide

Selection Tips 1. Confirm key dimension: ID 56mm, OD 112mm, width 8/10mm, verify shaft and housing bore size. 2. Cross‑check OEM number 4K14681. Select NBR for standard automotive oil conditions; choose FKM upgraded version for high‑temperature service. 3. Inspect shaft and housing bore before installation. Repair grooves, rust and burrs, otherwise newly fitted seal will leak prematurely. Installation Steps Preparation Thoroughly clean housing bore and shaft surface, remove old seal residue, grease dirt, metal chips and burrs. Damaged mating surface directly causes premature oil‑seal leakage. Pre‑lubrication Coat sealing lip and shaft contact surface with matching engine oil or grease. Dry installation is strictly forbidden; dry friction will rapidly damage sealing lip. Orientation Confirmation Sealing lip faces toward oil chamber side; dust lip faces outward to atmosphere. Wrong orientation will cause direct oil leakage and loss of dust‑proof function. Vertical Press‑fit Use suitable sleeve tool to press seal evenly and vertically. Never strike rubber portion directly to avoid shell deformation and lip damage. Seating Inspection Ensure oil seal sits fully flush inside housing bore without tilt or warping. Visual Check Inspect sealing lip for tears and shell deformation. Tiny invisible damage will develop into oil seepage later. Rotation Test Manually rotate shaft for smooth movement without abnormal binding resistance. Re‑assemble if abnormal resistance occurs.
