Selection & Installation
Selection Tips
- Confirm key dimension: ID 56mm, OD 112mm, width 8/10mm, verify shaft and housing bore size.
- Cross‑check OEM number 4K14681. Select NBR for standard automotive oil conditions; choose FKM upgraded version for high‑temperature service.
- 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.

FAQ
I only have a competitor/OEM part number—can you cross-reference?
Yes. Send the reference PN, ID×OD×height in mm, and duty (media, temperature, pressure, speed). We match equivalents in the catalog; the Cross Reference page also searches by keyword. Final selection follows drawing and duty confirmation — do not order from a photo alone.
Do you support OEM/ODM, private packing and marking?
Yes — OEM/ODM from drawings or samples, plus agreed packing and marking. Share target-market compliance needs and annual volume; RFQ confirms process, tooling cost and cadence. VKEFOT is the export brand of the Xingtai factory, not a trading desk.
TC vs TB oil seal: which should I specify?
For a rotary shaft that needs a dust lip plus oil lip, start with TC (rubber-covered dual-lip is common); TB is typical when a semi-metal case needs a stiffer bore fit. Shaft diameter, housing, runout and dust still decide. Send ID×OD×height in mm and speed on the RFQ — not only a competitor photo.
NBR vs FKM oil seal for hot engine oil?
Continuous engine-oil duty near 120°C or fuel exposure should be reviewed as FKM; general mineral oil at moderate temperature and cost-sensitive repair jobs often stay NBR. Brown color is not proof of FKM. The quote names the grade and temperature limit — do not order by color.
Oil seal vs O-ring: when do I use which?
Use a metal-cased radial shaft (skeleton) oil seal for rotating shafts; use an O-ring for static glands or reciprocating grooves. An O-ring on a rotary shaft wears out quickly. VKEFOT makes both — state motion type (rotary/static/reciprocating) and ID×OD×section on the RFQ.
Cassette seal vs dual-lip TC for dusty construction equipment?
Ag gearboxes and construction travel shafts with mud and long service intervals should be reviewed as cassette/combined seals; many automotive hub repair jobs stay dual-lip TC. Cassette packs are thicker and need different bore and axial space. A job-site photo is not enough — send ID×OD×height.
Xingtai oil seal factory vs trading company — how do I tell?
VKEFOT is the export brand of Xingtai Hanchi Intelligent Technology Co., Ltd. Mixing, vulcanization and outgoing inspection run in Xingtai, then goods export to Europe, North America, the Middle East and Southeast Asia. A trading desk usually cannot change compound or cut tooling. For OEM drawings, ask who runs the process and QC — not only catalog price.
What is a skeleton / radial shaft oil seal?
A skeleton oil seal is a metal-cased radial shaft seal: the rubber lip rides the shaft and the case holds interference in the bore. Common styles include TC, TB and TA. Minimum spec is ID×OD×height in mm, compound and duty. VKEFOT catalogs automotive and industrial shaft seals; trust the product-page dimensions.
What do ID, OD and height mean on an oil seal RFQ?
ID is inside diameter (shaft), OD is outside diameter (bore), height is axial width, all in millimetres. Missing any one blocks a cross-reference. Example: 56×112×8/10 means 56 mm ID, 112 mm OD, 8/10 mm height. Put those three numbers and the compound on the RFQ.
Which oil seal for an automotive wheel hub or differential pinion?
Hub repair jobs often use dual-lip TC; differential pinion shafts often need a secondary lip or split height (e.g. 8/10 or 12/22 mm). Use measured or OEM dimensions — not a marketplace title. VKEFOT application pages cover drivetrains and hubs; send an OEM number or ID×OD×height on the RFQ.
How to select oil seals for ag gearbox and PTO shafts?
Ag gearboxes and PTO shafts see dust and shock — prefer a dust lip or cassette, with NBR or FKM matched to gear oil and temperature. Do not force a passenger-car hub seal onto a PTO shaft. Send shaft, bore, height and whether mud/water is present, then RFQ.
What matters for pump, valve and compressor shaft seals?
Match media (oil, water, gas) and temperature first, then lip style and compound; do not default to cheap NBR for high speed or dry running. Put shaft runout and eccentricity on the RFQ. VKEFOT application cases include pumps, valves and compressors — still use measured sizes.
Does a brown oil seal mean it is FKM?
No. Brown NBR is common; color is not proof of FKM. For heat or fuel duty, write temperature and media on the RFQ so the factory names the grade. Ordering by color is a frequent cause of early leak.
Can you quote an oil seal from a photo only?
Not as a firm quote. We need at least ID×OD×height in mm, ideally compound and speed. A photo can show lip count and case style; it does not replace dimensions. Incomplete RFQs get a request for those three numbers before price.
If a new oil seal leaks quickly, is it always a bad seal?
Not always. Rough shaft finish, runout, cocked installation or the wrong compound also leak early. Check size and media/temperature match before blaming the part, then inspect the journal. Note time-to-fail (e.g. 50 hours) on the RFQ so we diagnose — do not just buy a cheaper seal.
What is needed for private-label OEM packing of oil seals?
Private packing and marking need annual volume, target-market compliance and artwork; tooling cost and cadence are confirmed on the RFQ — not a one-line “please OEM”. VKEFOT runs OEM/ODM after drawings or samples are complete.
Who is VKEFOT and how does it relate to Xingtai Hanchi?
VKEFOT manufactures oil seals, O-rings and custom rubber seals in Xingtai and exports to Europe, North America, Middle East and Southeast Asia. The manufacturer is Xingtai Hanchi Intelligent Technology Co., Ltd. Use this wording on quotes and certificates — do not invent alternate spellings of the brand.
