TC Skeleton Oil Seal — Stop Leaks on Rotary Shafts with FKM Fluorine Rubber

A leaking shaft seal is one of the most frustrating failures in any engine, gearbox, or hydraulic system — oil escapes, contaminants enter, and the damage compounds fast. Whether you're a mechanic rebuilding a differential, a maintenance tech servicing an industrial pump, or a DIYer tackling a tractor repair, having the right TC skeleton oil seal on hand means the job gets done right the first time.

Each seal is a TC double-lip design with a steel skeleton and a garter spring-loaded primary lip, manufactured from FKM (fluorine rubber / Viton-type) with a hardness of ±70 HA and a characteristic brown color. Available in a wide range of sizes with outside diameters from 78mm (≈3.07") to 235mm (≈9.25"), inside diameters from 62mm (≈2.44") to 200mm (≈7.87"), and seal heights from 7mm (≈0.28") to 18mm (≈0.71"). Select your exact size from the variant options above.

These TC lip seals are well-suited for automotive crankshaft and camshaft sealing, gearbox and differential output shaft sealing, and industrial pump and compressor shaft sealing — anywhere a rotating shaft passes through a housing and lubrication retention is critical.

🔵 Compatibility Note: TC skeleton oil seals are sized by three dimensions — Inside Diameter (ID) × Outside Diameter (OD) × Height. Always verify all three measurements against your equipment's shaft and housing bore before ordering. When in doubt, consult your service manual or contact us to confirm.

✅ Key Features of These TC Skeleton FKM Oil Seals

🌡️ Wide Temperature Range — FKM fluorine rubber handles continuous operating temperatures from -20°C (-4°F) to 250°C (482°F), making these seals reliable in high-heat engine and hydraulic applications where standard NBR seals fail prematurely.
🛡️ Dual-Lip TC Design — The spring-loaded primary lip retains lubricant while the secondary dust lip actively excludes dirt, water, and debris — a critical advantage in agricultural, off-road, and industrial environments.
⚗️ Chemical-Resistant FKM Compound — Fluoroelastomer construction resists petroleum oils, hydraulic fluids, fuels, and many industrial solvents, making these rotary shaft lip seals suitable for demanding fluid environments.
🔩 Steel Skeleton Reinforcement — The embedded metal skeleton maintains the seal's round shape during press-fit installation and prevents distortion under housing pressure, ensuring consistent sealing contact around the full shaft circumference.
📐 Broad Size Range — With OD from 78mm to 235mm and ID from 62mm to 200mm, this product line covers a wide variety of shaft sizes across automotive, agricultural, and industrial machinery — reducing the need to source from multiple suppliers.
🔄 Drop-In Replacement Fit — TC-type seals follow widely adopted dimensional standards, so these seals are generally interchangeable with OEM and aftermarket TC oil seals of the same ID × OD × height specification.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

You need three measurements: shaft diameter (inner diameter / ID), bore diameter (outer diameter / OD), and seal height. For example, a seal marked 80×100×10 means ID 80mm (≈3.15"), OD 100mm (≈3.94"), height 10mm (≈0.39"). Always measure the housing bore and shaft before ordering. When in doubt, consult your equipment manual or contact us to confirm.

What temperature range can these FKM oil seals handle?

These seals are made from FKM (fluorine rubber / Viton-type) and are rated for continuous use from -20°C (-4°F) to 250°C (482°F). They generally outperform standard NBR seals in high-heat environments such as engine bays, hydraulic systems, and industrial machinery.

Are these oil seals resistant to chemicals and oils?

Yes. FKM (fluoroelastomer) is typically resistant to petroleum-based oils, hydraulic fluids, fuels, and many industrial solvents. It generally outperforms NBR and EPDM in aggressive chemical environments. For highly concentrated acids or ketones, contact us to confirm compatibility.

What does "TC" mean in TC skeleton oil seal?

"TC" refers to a double-lip seal design with a metal skeleton (spring-loaded inner lip). The primary lip retains lubricant while the secondary dust lip keeps contaminants out. This dual-lip construction is the most common standard for rotary shaft sealing in automotive and industrial applications.

Can I use these seals outdoors or in wet environments?

FKM seals are generally suitable for outdoor and wet environments. The secondary dust lip helps exclude water and debris. However, prolonged submersion in water is not a typical use case — if your application involves full immersion, contact us to confirm the best seal type.

What equipment are TC skeleton oil seals typically used in?

TC skeleton oil seals are commonly used in automotive engines, gearboxes, differentials, pumps, compressors, agricultural machinery, and industrial motors — anywhere a rotating shaft passes through a housing and lubrication must be retained.

How do I install a TC oil seal correctly?

Clean the housing bore and shaft. Apply a thin film of clean grease or oil to the seal lip and bore. Press the seal in squarely using a seal driver or a flat block — never hammer directly on the seal face. Ensure the seal sits flush or slightly below the housing surface. Avoid nicking the lip during installation.
