FKM Rotary Shaft Oil Seal TC Double Lip — Stop Leaks and Contamination for Good

If you've dealt with oil weeping past a worn shaft seal — or grit and moisture working its way into a gearbox — you know how quickly a small sealing failure turns into a costly repair. Mechanics, equipment operators, and DIY rebuilders working on engines, transmissions, axles, and industrial machinery need a shaft seal that holds up to heat, chemical exposure, and real-world contamination. These FKM rotary shaft oil seals are built for exactly that.

Each seal is a TC-profile double lip design made from FKM (Fluorine rubber / Viton-equivalent), a high-performance elastomer rated from -30°C to 250°C (-22°F to 482°F) with a Shore hardness of 70. The inner diameter options covered in this listing are 62, 63, 64, 65, 68, 70, 72, 74, and 75mm (approximately 2.44" to 2.95"). A garter spring behind the primary lip maintains consistent radial sealing force throughout the seal's service life. Outer diameter and width vary by size — see variant options for your specific dimensions.

These FKM TC double lip oil seals are ideal for automotive drivetrain rebuilds (crankshaft seals, differential pinion seals, axle shaft seals), industrial gearbox and pump shaft sealing, and agricultural or construction equipment where shafts are exposed to dust, mud, and temperature extremes. The working media compatibility includes mineral oil, synthetic oil, and water — making them a versatile rotary shaft seal for grease and oil retention applications.

🔵 Compatibility Note: Match your shaft's outer diameter to the seal's inner diameter (ID). Confirm housing bore and seal width before ordering. Available IDs: 62 / 63 / 64 / 65 / 68 / 70 / 72 / 74 / 75mm. Select your size from the variant dropdown above.

✅ Key Features of These FKM TC Double Lip Rotary Shaft Oil Seals

🌡️Wide Temperature Range — Rated from -30°C to 250°C (-22°F to 482°F), these FKM shaft seals maintain elasticity and sealing integrity in both cold-start conditions and sustained high-heat environments like engine bays and industrial ovens.
💧TC Double Lip Design — The primary lip with integrated garter spring retains oil and grease under dynamic shaft rotation, while the secondary dust lip actively excludes dirt, water, and airborne contaminants — a critical advantage over single-lip SC seals in exposed applications.
⚗️FKM Chemical Resistance — Fluorine rubber (FKM) resists degradation from mineral oils, synthetic lubricants, hydraulic fluids, and water — outperforming standard NBR (nitrile) seals in chemically aggressive or high-temperature fluid environments.
🔩Garter Spring for Consistent Lip Load — The embedded garter spring applies uniform radial force around the shaft, compensating for minor shaft runout and housing misalignment to maintain a reliable seal over extended service intervals.
📐Multiple ID Sizes in One Listing — Inner diameters from 62mm to 75mm (≈2.44" to 2.95") are available as variants, covering a broad range of shaft sizes common in automotive transmissions, axles, and industrial rotating equipment.
🏭Broad Application Compatibility — Suitable for use with mineral oil, synthetic oil, and water as working media — making these TC-type rotary shaft seals a practical choice for automotive, agricultural, marine, and general industrial machinery.

❓ Frequently Asked Questions

How do I choose the right inner diameter for my shaft?

Measure your shaft's outer diameter with calipers. The seal's inner diameter (ID) should match the shaft OD exactly. This listing covers IDs of 62, 63, 64, 65, 68, 70, 72, 74, and 75mm (approximately 2.44" to 2.95"). If you are unsure, contact us to confirm before ordering.

What pressure can these FKM oil seals handle?

TC-type rotary shaft seals are generally designed for low-to-moderate pressure applications. They are typically rated for dynamic sealing at shaft surface speeds up to around 4–8 m/s. For high-pressure hydraulic circuits, a different seal type is recommended. Contact us to confirm suitability for your specific application.

Can these seals be used outdoors or in wet environments?

Yes. The secondary dust lip on the TC profile is specifically designed to exclude water, dirt, and environmental contaminants from the shaft. FKM rubber also offers good resistance to moisture and weathering, making these seals suitable for outdoor machinery and equipment exposed to the elements.

What fluids are compatible with FKM oil seals?

FKM (Fluoroelastomer) is compatible with mineral oils, synthetic oils, hydraulic fluids, and water. It is generally not recommended for use with ketones, certain esters, or steam above 250°C. Always verify compatibility with your specific fluid before installation.

How do I know if a TC seal will fit my housing bore?

You need to match three dimensions: inner diameter (ID) to shaft OD, outer diameter (OD) to housing bore, and seal width to housing depth. Select your size variant from the dropdown above. If your housing bore dimension is not listed, contact us — we can help identify the correct match.

What is the difference between a TC seal and a SC or SB seal?

A TC seal has two sealing lips — a primary oil lip with a garter spring for consistent radial load, and a secondary dust/dirt exclusion lip. An SC seal has only the primary lip. A TC seal is generally preferred when the shaft is exposed to contaminants, dust, or moisture, which is the case in most automotive and industrial applications.

Can I use this seal in automotive transmissions and engines?

Yes. FKM TC double lip seals are widely used in automotive applications including gearboxes, differentials, crankshafts, and axle shafts. The FKM compound's resistance to high temperatures (up to 250°C) and transmission fluids makes it a reliable choice for engine and drivetrain sealing.
