What thread or shaft standards are these seals compatible with?

These are metric-dimensioned oil seals compatible with metric shafts and housings. The inner diameter (ID) must match your shaft diameter exactly. Common applications include shafts following ISO, DIN, and JIS standards. Always verify the shaft OD and housing bore before ordering.

TC Double Lip NBR Oil Seal — 15mm, 16mm & 17mm ID Rotary Shaft Seal for Every Depth

When a leaking shaft seal causes oil contamination, bearing failure, or costly downtime, finding the exact replacement fast is critical. Whether you are a professional mechanic, equipment technician, or serious DIYer, these TC double lip NBR oil seals cover inner diameters of 15mm, 16mm, and 17mm with an extensive range of outer diameters and depths — so you can match your housing precisely without compromise.

Each seal is manufactured to the TC / R23 / TTO double-lip standard in NBR (nitrile rubber) with a carbon steel case. Inner diameters span 15mm (≈0.591"), 16mm (≈0.630"), and 17mm (≈0.669"). Outer diameters range from 21mm to 52mm (≈0.83"–2.05"), and depths run from 3mm to 12mm (≈0.12"–0.47"), covering the most common metric shaft seal sizes in this range. Available in packs of 1, 5, or 10 pieces depending on the selected size.

Typical applications include small engine crankshaft seals, gearbox input shaft seals, agricultural equipment rotary shaft seals, pump housings, and automotive differential pinion seals where a metric 15–17mm ID double lip oil seal is specified. The NBR compound handles petroleum-based oils, greases, and water, making it a reliable choice for general-purpose sealing in both indoor and outdoor machinery.

⚠️ Always verify your shaft OD, housing bore, and housing depth before ordering. Dimensions are listed as Inner Ø × Outer Ø × Depth (all in mm).

🔵 Compatibility: Metric shafts with 15mm, 16mm, or 17mm outer diameter. Housing bore must match the listed outer diameter. Conforms to TC / R23 / TTO double-lip seal geometry per ISO 6194 / DIN 3760 standards.

✅ Key Features of These TC Double Lip NBR Oil Seals

🔒Double-Lip TC Design — The primary sealing lip retains lubricant while the secondary dust lip blocks contaminants, providing dual-barrier protection for rotary shaft applications in dirty or wet environments.
🧪NBR Nitrile Rubber Compound — Resistant to petroleum oils, hydraulic fluids, greases, and water; generally rated for continuous service from approximately −40°F to +250°F (−40°C to +120°C).
📐Extensive Size Matrix — Inner diameters of 15mm, 16mm, and 17mm paired with outer diameters from 21mm to 52mm and depths from 3mm to 12mm, covering hundreds of metric shaft seal combinations in a single listing.
🏗️Carbon Steel Case — The rigid outer shell ensures a secure press-fit into the housing bore, maintaining concentricity and preventing seal rotation during operation.
⚙️Garter Spring Loaded Lip — An internal garter spring maintains consistent radial lip pressure against the shaft, compensating for minor shaft runout and extending service life in rotary shaft seal applications.
📦Flexible Pack Quantities — Order 1, 5, or 10 pieces per size to suit single repairs, workshop stock, or production line requirements — availability varies by dimension.

❓ Frequently Asked Questions

How do I choose the right depth (width) for my TC oil seal?

Measure the bore depth in your housing and match it to the seal's listed depth dimension. For example, a seal listed as 15 × 25 × 7 has an inner diameter of 15mm, outer diameter of 25mm, and a depth of 7mm (≈0.28"). When in doubt, choose a depth that fits flush with or slightly below the housing face to allow proper installation without bottoming out.

What does "TC" or "double lip" mean on an oil seal?

TC (also designated R23 or TTO) refers to a double-lip design: the primary lip retains oil or grease inside the housing, while the secondary dust lip prevents external contaminants — dirt, water, and debris — from entering the bearing or shaft area. This dual-barrier design is generally preferred over single-lip seals in environments with exposure to dirt, moisture, or road splash.

What is the pressure or load rating of these oil seals?

TC-type NBR oil seals are typically designed for low-to-medium pressure applications. They are generally suitable for static pressures up to approximately 0.3 bar (≈4.4 psi) and are not intended for high-pressure hydraulic circuits. For dynamic shaft sealing at higher pressures, a hydraulic rod seal or PTFE-lipped seal may be more appropriate. Contact us to confirm suitability for your specific application.

Can these seals be used outdoors or in wet environments?

NBR nitrile rubber offers good resistance to water, petroleum oils, and mild chemicals, making it generally suitable for outdoor and wet environments. However, NBR is not recommended for prolonged exposure to ozone, strong UV radiation, or aromatic fuels. For highly aggressive outdoor or chemical environments, a Viton (FKM) seal may be more appropriate. The double-lip design adds an extra layer of protection against water ingress.

What shaft and housing standards are these seals compatible with?

These are metric-dimensioned oil seals compatible with metric shafts and housings following ISO, DIN, and JIS standards. The inner diameter must match your shaft OD exactly (15mm, 16mm, or 17mm), and the outer diameter must match your housing bore. Always verify both dimensions — and the housing depth — before ordering. These seals are not designed for inch-standard (SAE) shafts without confirming dimensional equivalence.

How do I convert the seal dimensions from mm to inches?

Divide the millimeter value by 25.4 to convert to inches. Quick reference:

15mm ≈ 0.591"
16mm ≈ 0.630"
17mm ≈ 0.669"
7mm depth ≈ 0.276"
25mm OD ≈ 0.984"
35mm OD ≈ 1.378"
47mm OD ≈ 1.850"

For any specific size in this listing, divide the listed mm value by 25.4 for the inch equivalent.

Which pack size should I order — 1, 5, or 10 pieces?

If you are completing a single repair, a pack of 1 or 5 is typically sufficient. For workshop stock, fleet maintenance, or production use, a pack of 10 offers better per-unit value. Pack availability varies by size — select your dimension first, then check the Packing Quantity option to see which quantities are available for that specific seal.
