TC Nitrile Rubber Oil Seals ID 22–30mm — Stop Leaks Before They Stop Your Machine

Mechanics, equipment owners, and DIY rebuilders know the frustration of a weeping gearbox or a bearing housing that keeps losing lubricant. A worn or mismatched oil seal is usually the culprit — and sourcing the exact metric size quickly can be a challenge. These TC nitrile rubber oil seals cover inner diameters from 22mm to 30mm (≈0.87" to 1.18") across a wide range of OD and height combinations, giving you the right fit for the job without waiting on a specialty order.

Each seal is a double-lip TC (LIPR) design constructed from nitrile rubber (NBR) with a carbon steel outer case. Available sizes span ID×OD×H combinations from 22×42×7mm (≈0.87"×1.65"×0.28") up to 30×45×10mm (≈1.18"×1.77"×0.39"), with many intermediate dimensions in between. Packs are available in 5, 10, 20, or 50 pieces to suit single repairs or workshop stock.

Typical use cases include automotive gearbox and differential rebuilds, agricultural and small-engine bearing housings, industrial pump shafts, and general-purpose machinery where a reliable radial shaft seal is needed to retain oil and exclude dust or moisture.

ℹ️ Compatibility Note: These are metric TC oil seals. Always verify your shaft ID, housing bore OD, and housing depth (H) before ordering. Dimensions are listed as ID×OD×H in mm on each variant. Inch conversions: 1mm ≈ 0.0394".

✅ Key Features of These TC Nitrile Rubber Oil Seals

🔒Double-Lip TC Design — The primary sealing lip retains lubricant while the secondary dust lip blocks contaminants, making these seals effective in dirty or wet environments where single-lip seals fall short.
🧪Nitrile Rubber (NBR) Construction — NBR offers solid resistance to petroleum-based oils, water, and mild chemicals, covering the majority of gearbox, differential, and pump applications without special fluid compatibility concerns.
🌡️Water & Heat Resistant — Rated for typical operating temperatures from approximately -40°F to +250°F (-40°C to +120°C), suitable for both cold-start conditions and sustained running temperatures in bearing housings.
⚙️Carbon Steel Outer Case — The rigid metal shell provides a secure press-fit into standard machined bores, maintaining concentricity and preventing the seal from spinning or walking out under vibration.
📐Wide Size Range in One Listing — Covers ID 22mm through 30mm with multiple OD and height options, reducing the need to source from multiple suppliers when rebuilding equipment with varied bearing sizes.
📦Flexible Pack Quantities — Available in 5, 10, 20, or 50-piece packs, so you can buy exactly what you need for a single repair or keep a practical stock on hand for recurring maintenance work.

⚠️ Before You Order: Confirm your three dimensions — shaft ID, housing bore OD, and housing depth H — with calipers. A seal that is even 1mm off in OD will not seat correctly. If you are unsure, contact us with your measurements.

❓ Frequently Asked Questions

How do I choose the right oil seal size for my application?

Measure the shaft diameter (ID), the bore diameter (OD), and the housing depth (H) with calipers. Match those three dimensions to the variant listed as ID×OD×H in mm. For example, 25×42×7mm means a 25mm shaft, 42mm bore, 7mm height (≈0.98" × 1.65" × 0.28"). When in doubt, go by the shaft diameter first, then confirm OD fits your housing.

What is the difference between a TC and a SC oil seal?

A TC seal has two sealing lips — a primary lip that contacts the shaft and a secondary dust lip that keeps contaminants out. An SC seal has only one lip. TC seals are generally preferred for applications exposed to dirt, moisture, or splash, making them the standard choice for most bearing housings and gearboxes.

What pressure and temperature range can these oil seals handle?

Nitrile rubber (NBR) TC oil seals typically handle temperatures from approximately -40°F to +250°F (-40°C to +120°C) and are rated for low-pressure applications (generally up to about 7 psi / 0.5 bar). For high-pressure or high-temperature environments, contact us to confirm suitability.

Are these oil seals suitable for outdoor or wet environments?

Yes. Nitrile rubber is resistant to water, petroleum-based oils, and mild chemicals, making these seals well-suited for outdoor machinery, agricultural equipment, and applications exposed to splash or humidity. For prolonged saltwater or chemical immersion, contact us to confirm compatibility.

What shaft speed can these seals accommodate?

NBR TC oil seals are typically suitable for shaft surface speeds up to approximately 4–6 m/s (800–1,200 ft/min) under normal lubricated conditions. Actual performance depends on shaft finish, lubrication, and operating temperature. Contact us to confirm for high-speed applications.

What bore or thread standard do these seals follow?

These are metric-dimensioned TC oil seals conforming to general ISO/DIN standards for radial shaft seals. The OD is designed for a press-fit into a standard machined bore. Dimensions are listed in mm (ID×OD×H). Approximate inch equivalents: 22mm ≈ 0.866", 25mm ≈ 0.984", 28mm ≈ 1.102", 30mm ≈ 1.181".

How do I install a TC oil seal correctly?

Clean the bore and shaft. Lightly lubricate the seal lip with the fluid being sealed. Press the seal squarely into the bore using a seal driver or a flat block — never hammer directly on the seal face. Ensure the primary lip faces the fluid side. Avoid nicking the lip on shaft keyways or threads during installation.

Can I use these seals in a gearbox or differential?

In most cases, yes. NBR TC oil seals are compatible with petroleum-based gear oils and ATF fluids commonly used in gearboxes and differentials. Verify that your fluid does not contain aggressive EP additives at concentrations that may degrade NBR over time. When in doubt, contact us with your fluid specification.
