68–74mm ID Rubber Double Lip TC Oil Shaft Seal — Reliable Sealing for Car & Automotive Applications

When a worn or leaking shaft seal causes oil to seep past rotating components, it can contaminate brakes, damage bearings, and lead to costly repairs. Mechanics, DIY enthusiasts, and small-batch repair shops working on passenger cars, light trucks, and agricultural equipment need a seal they can trust to hold under heat and pressure. These rubber double lip TC oil shaft seals are engineered to stop leaks at the source and restore proper lubrication containment.

Each seal is constructed with a nitrile rubber (NBR) sealing body bonded to a steel reinforcement ring, forming the industry-standard TC (double lip) profile. The primary lip retains oil while the secondary dust lip blocks contaminants from entering the bearing cavity. Inner diameters span 68 mm to 74 mm (approximately 2.68 in to 2.91 in), outer diameters range from 80 mm to 150 mm (approximately 3.15 in to 5.91 in), and seal depths range from 5 mm to 20 mm (approximately 0.20 in to 0.79 in) across the full variant lineup. Available in packs of 1, 5, or 10 pieces to suit single-vehicle repairs or workshop stock.

Typical use cases include rear axle shaft seal replacement on rear-wheel-drive vehicles, front differential pinion seal service on 4WD trucks, gearbox output shaft resealing on manual transmissions, and agricultural PTO shaft seal maintenance — all scenarios where a precise-fit double lip TC seal is the correct specification.

🔧 Compatibility: Designed for shafts with inner diameters of 68, 69, 69.8, 70, 71, 72, 73, 73.025, or 74 mm. Match your shaft OD and housing bore to the variant dimensions (Inner Ø × Outer Ø × Depth) before ordering. Consult your vehicle service manual to confirm the correct seal specification.

✅ Key Features of These TC Oil Shaft Seals

💧

Double Lip TC Profile

The primary NBR lip seals in oil; the secondary dust exclusion lip blocks dirt, water, and debris from reaching the bearing — the standard TC configuration for automotive shaft sealing.

🔩

Steel-Reinforced Shell

A stamped steel outer case maintains dimensional stability during press-fit installation and prevents the seal from spinning or distorting under operating loads.

🌡️

NBR Rubber Compound

Nitrile butadiene rubber offers resistance to petroleum-based engine oils, gear oils, and ATF across a typical operating temperature range of −40 °C to +120 °C (−40 °F to +248 °F).

📐

Wide Size Coverage

Inner diameters from 68 mm to 74 mm with dozens of outer diameter and depth combinations cover a broad range of axle, differential, gearbox, and PTO shaft applications in a single product listing.

📦

Flexible Pack Quantities

Choose 1-piece, 5-piece, or 10-piece packs. Single-piece packs suit one-off repairs; multi-piece packs reduce per-unit cost for workshop stock or fleet maintenance programs.

⚙️

Press-Fit Installation

The machined outer diameter is sized for a firm interference fit into standard housing bores. Use a seal driver or socket of the correct outer diameter for flush, square installation without lip distortion.

❓ Frequently Asked Questions

How do I choose the correct seal size for my vehicle?

Measure the shaft outer diameter (this becomes the seal inner diameter), the housing bore diameter (this becomes the seal outer diameter), and the housing depth available for the seal. Cross-reference these three dimensions with the variant option "Inner Ø × Outer Ø × Depth" listed in millimetres. Always verify against your vehicle's service manual or OEM parts catalogue before ordering.

What does "TC" mean in TC oil seal?

"TC" is an industry designation for a double-lip radial shaft seal with a metal case. The primary lip (with a garter spring) retains lubricant, while the secondary lip acts as a dust and contaminant exclusion barrier. This two-lip design makes TC seals the standard choice for automotive axle, differential, and gearbox applications.

Are these seals resistant to gear oil and ATF?

Yes. The nitrile rubber (NBR) compound used in these seals is compatible with petroleum-based engine oils, conventional gear oils (GL-4 / GL-5), and most automatic transmission fluids (ATF). NBR is not recommended for use with synthetic ester-based fluids or silicone oils — check your fluid specification if in doubt.

What is the operating temperature range?

NBR rubber maintains its sealing properties from approximately −40 °C to +120 °C (−40 °F to +248 °F). This covers the typical thermal range of automotive axle and gearbox applications. For applications with sustained temperatures above 120 °C, consider a PTFE or FKM (Viton) lip seal instead.

How do I install a TC oil seal without damaging the lip?

Clean the housing bore and lightly lubricate the seal lip with the same oil the seal will retain. Use a seal driver or a flat-faced socket matching the seal outer diameter to press the seal in squarely and flush with the housing face. Never hammer directly on the seal body. Protect the primary lip from sharp shaft edges or keyways during installation — use a sleeve or tape if necessary.

Can I order a single piece to replace one failed seal?

Yes. Select the correct size variant and then choose "1" from the Packing Quantity (pcs) option. Single-piece pricing is available for most size combinations. If you are stocking a workshop or performing a full axle rebuild, the 5-piece or 10-piece packs offer a lower per-unit cost.

Will these seals fit both metric and imperial shaft sizes?

The seals are dimensioned in millimetres. One variant (73.025 × 92.075 × 9.25 mm) corresponds to the imperial equivalent of approximately 2.875" × 3.625" × 0.364", which is a common imperial axle seal size. For all other variants, confirm your shaft and bore dimensions in millimetres before selecting.

These o rings are a great for my ear tunnels

These o rings are a great for my ear tunnels, always loosing one here and there, I always have a new ones in the drawer. Being silicone, don't have any reactions compared to standard rubber ones I purchased at hardware stores, plus much less expensive. Purchased 16mm I'd to use on 19mm tunnels, and stay on great, might be able to get away with 17mm rings, but really happy with my choice.

Will never order from these folks again

I waited a long time and that’s all I received was the eyebolt with no threaded rod attached to it

Perfect they are really made well and I used them for my car

Perfect they are really made well and I used them for my car. The only thing I had a great for us. It took three weeks to get here. So shipping was slow.

did not include wing nuts
