TC Oil Seals ID 15 16 17mm — Stop Shaft Leaks with FKM Dual Lip Protection

A weeping gearbox, a dripping pump shaft, or an oil-soaked engine bay — shaft seal failures are messy, costly, and almost always avoidable. Whether you're rebuilding a small engine, servicing a hydraulic pump, or replacing a worn seal on a power tool, having the exact-fit TC oil seal on hand is the difference between a 20-minute fix and a full teardown. These seals are built for mechanics, equipment technicians, and serious DIYers who need a reliable metric seal without hunting through a dealer's parts catalog.

Each seal follows the TC (double-lip) profile: a steel-reinforced outer casing pressed into the bore, a primary FKM rubber sealing lip that rides the shaft, and a secondary dust-exclusion lip that keeps contaminants out. Inner diameters are 15mm (≈0.591"), 16mm (≈0.630"), or 17mm (≈0.669"), with outer diameters ranging from 21mm up to 47mm and thicknesses from 4mm to 10mm — available in 1, 2, or 5-piece packs. Select the exact ID × OD × Thickness combination that matches your housing and shaft.

Typical use cases include small engine crankshaft seals, gearbox input and output shaft seals, hydraulic cylinder rod seals, rotary pump shaft seals, and agricultural or outdoor power equipment. The FKM compound handles petroleum-based oils, gear lubricants, and many synthetic fluids, making these seals a dependable choice wherever a standard NBR seal would fall short due to heat or chemical exposure.

🔵 Compatibility Note: These are metric TC-profile seals. Verify your shaft ID, bore OD, and housing depth before ordering. Dimensions are listed as ID × OD × Thickness in millimeters. Not designed for inch-standard bores — confirm fit if substituting for an imperial-size seal.

⚠️ Tip: If you are unsure of your exact seal dimensions, measure the old seal with calipers or contact us with your equipment make/model and we will help confirm the correct size.

✅ Key Features of These TC FKM Rotary Shaft Oil Seals

🛡️Dual Lip TC Design — The primary lip seals lubricant in; the secondary lip blocks dirt, dust, and moisture out — two lines of defense in one compact seal.
🔥FKM (Viton) Rubber Compound — Rated for continuous service up to approximately 200°C (392°F), FKM outperforms standard NBR in high-heat engines, gearboxes, and chemical-exposure environments.
⚙️Steel-Reinforced Outer Casing — The rigid metal shell ensures a secure press-fit into the bore housing, preventing rotation and maintaining concentricity under vibration.
📐Wide Size Selection — ID 15mm, 16mm, or 17mm with OD options from 21mm to 47mm and thicknesses from 4mm to 10mm — covering a broad range of metric rotary shaft seal applications.
🧪Oil & Chemical Resistance — Compatible with petroleum-based oils, gear lubricants, and many synthetic fluids; FKM rubber resists swelling and degradation where NBR seals typically fail.
📦Flexible Pack Quantities — Order 1, 2, or 5 pieces per size. Multi-packs reduce per-unit cost and keep a spare ready for the next service interval.

❓ Frequently Asked Questions

How do I choose the right oil seal size?

Measure the shaft inner diameter (ID), the bore outer diameter (OD), and the housing depth (thickness). Match all three dimensions to the variant listed as ID × OD × Thickness. For example, a 15×30×7mm seal fits a 15mm shaft, a 30mm bore, and a 7mm deep housing. When in doubt, measure twice — a seal that is even 0.5mm off will not seat or seal correctly.

What load or pressure can these oil seals handle?

TC-type rotary shaft seals are generally rated for low-to-moderate shaft speeds and pressures up to approximately 0.05 MPa (7 psi) in most standard applications. For higher-pressure systems, a pressurized seal housing or a different seal type is typically required. Contact us to confirm suitability for your specific application.

Are these seals suitable for outdoor or wet environments?

Yes. The FKM (Viton) rubber compound offers excellent resistance to water, humidity, and many chemicals. FKM generally outperforms NBR in outdoor and high-temperature environments, making these seals a solid choice for garden equipment, outdoor power tools, and marine-adjacent applications. Avoid prolonged exposure to ketones or certain esters without confirming chemical compatibility.

What shaft standards are these seals compatible with?

These are metric TC-profile seals compatible with metric shafts and bores. The ID dimensions (15mm, 16mm, 17mm) correspond to standard metric shaft diameters. They are not designed for inch-standard shafts, though some inch sizes are close — for example, 15mm ≈ 0.591" and 17mm ≈ 0.669". Always verify the exact bore and shaft dimensions before ordering.

Should I choose 1 PCS, 2 PCS, or 5 PCS?

Choose 1 PCS for a single repair or replacement. The 2 PCS pack is a good option if you have two identical shafts or want a spare on hand. The 5 PCS pack offers the best per-unit value and is ideal for workshops, fleet maintenance, or equipment with multiple sealing points of the same size.

What is the temperature range for FKM rubber oil seals?

FKM (Viton) rubber typically performs reliably from approximately -20°C (-4°F) up to +200°C (+392°F) in continuous service, with short-term peaks to around +230°C (+446°F). This makes FKM seals well-suited for engines, gearboxes, and other high-heat rotating equipment where standard NBR seals would degrade prematurely.

How do I install a TC oil seal without damaging it?

Use a seal driver or a flat block of wood to press the seal in evenly — never hammer directly on the seal face. Lightly lubricate the outer metal casing and the lip with clean oil or grease before installation. Ensure the shaft end is chamfered or deburred to avoid cutting the lip during assembly. Press until the seal face is flush with or just below the housing surface.
