What does FKM rubber mean for an oil seal?

FKM (Viton) is a fluoroelastomer that generally withstands temperatures from -20°C to +200°C (-4°F to +392°F) and resists petroleum oils, hydraulic fluids, and many chemicals better than standard NBR rubber seals.

Can these TC oil seals be used outdoors or in wet environments?

Yes. The dual-lip TC design includes a primary sealing lip to retain lubricant and a secondary dust/exclusion lip to block water, dirt, and debris. FKM rubber also offers good resistance to moisture and mild corrosive environments.

What shaft speed and pressure can these seals handle?

TC-type rotary shaft seals are typically rated for shaft surface speeds up to approximately 4–8 m/s and low-to-moderate pressure differentials (generally under 0.05 MPa). For high-speed or high-pressure applications, contact us to confirm suitability.

Are these seals compatible with metric shafts and housings?

Yes. All dimensions listed (ID × OD × Thickness) follow metric standards in millimeters, consistent with ISO 6194 and DIN 3760 TC-type seal profiles. They are designed for metric shafts and bores.

How do I install a TC skeleton oil seal correctly?

Clean the housing bore and shaft. Lightly lubricate the seal lip with the fluid being sealed. Press the seal in squarely using a seal driver or a flat plate — never hammer directly on the seal face. Ensure the seal sits flush or slightly below the housing face.

TC Skeleton Oil Seals ID 60–68mm — Stop Leaks on Rotating Shafts

When a gearbox starts weeping oil or a pump shaft leaves a puddle on the shop floor, the culprit is almost always a worn rotary shaft seal. These TC skeleton oil seals with FKM rubber dual lip are engineered for mechanics, maintenance technicians, and serious DIYers who need a reliable, drop-in replacement without hunting through a dealer's parts catalog.

Each seal ships as a single piece (1 PCS) or a value pack (5 PCS). The metal-reinforced TC skeleton body holds its shape under press-fit installation, while the FKM (Viton) elastomer lip resists petroleum oils, hydraulic fluids, and temperatures typically ranging from -20°C to +200°C (-4°F to +392°F). Inner diameters span 60mm, 62mm, 63mm, 65mm, and 68mm; outer diameters range from 70mm to 130mm; and lip thickness options run from 6mm to 13mm — covering a wide range of metric shaft and bore combinations in a single listing.

Typical applications include automotive differential and axle seals, agricultural tractor PTO and gearbox seals, hydraulic pump shaft seals, and industrial motor end-cap seals — anywhere a rotating shaft passes through a stationary housing and lubricant retention matters.

🔵 Compatibility Note: These are metric TC-type seals conforming to ISO 6194 / DIN 3760 profiles. Verify your shaft ID, housing bore OD, and housing depth (thickness) with calipers before ordering. Dimensions are listed as ID × OD × Thickness in millimeters.

✅ Key Features of These TC FKM Rubber Dual Lip Oil Seals

🛡️Dual-Lip TC Design — The primary lip retains lubricant while the secondary exclusion lip blocks dirt, dust, and water ingress, extending bearing and gear life in contaminated environments.
🔥FKM (Viton) Elastomer — Fluoroelastomer construction typically withstands continuous temperatures up to 200°C (392°F) and resists petroleum oils, ATF, hydraulic fluid, and mild chemicals better than standard NBR seals.
⚙️Metal-Reinforced Skeleton Body — The rigid steel inner skeleton maintains dimensional stability during press-fit installation and prevents the seal from collapsing or distorting under housing pressure.
📐Wide Size Range in One Listing — Inner diameters from 60mm to 68mm, outer diameters from 70mm to 130mm, and thicknesses from 6mm to 13mm cover dozens of metric shaft seal applications without ordering from multiple sources.
🔩Metric ISO / DIN Profile — Dimensioned to ISO 6194 and DIN 3760 TC-type standards, making these seals direct replacements for OEM metric rotary shaft seals in gearboxes, pumps, and axles.
📦Flexible Pack Quantities — Order 1 PCS for a single repair or 5 PCS for fleet maintenance or workshop stock — both options available for every size combination.

⚠️ Before You Order: Measure your shaft OD (= seal ID), housing bore ID (= seal OD), and housing depth (= seal thickness) with a vernier caliper. A seal that is even 1mm off in any dimension will not seal correctly.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

Measure three dimensions with calipers: (1) the shaft outer diameter — this becomes the seal's ID; (2) the housing bore inner diameter — this becomes the seal's OD; (3) the housing depth — this becomes the seal's Thickness. For example, a 65mm shaft in an 85mm bore with a 10mm housing depth requires a 65×85×10mm seal. Always confirm all three before ordering. As a quick inch reference: 60mm ≈ 2.36", 65mm ≈ 2.56", 68mm ≈ 2.68".

What does FKM rubber mean and why does it matter for oil seals?

FKM (also marketed as Viton) is a fluoroelastomer that generally withstands continuous temperatures up to 200°C (392°F) and resists petroleum oils, ATF, hydraulic fluids, and many chemicals far better than standard NBR (nitrile) rubber. If your application runs hot or uses synthetic fluids, FKM is typically the correct choice over NBR.

Can these seals be used outdoors or in wet, muddy environments?

Yes. The TC dual-lip design includes a primary sealing lip to retain lubricant and a secondary exclusion lip specifically to block water, mud, and debris from reaching the bearing. FKM rubber also offers good resistance to moisture and mild corrosive environments, making these seals well-suited for agricultural, construction, and outdoor power equipment.

What shaft speed and pressure can these TC seals handle?

TC-type rotary shaft seals are generally rated for shaft surface speeds up to approximately 4–8 m/s and low-to-moderate pressure differentials (typically under 0.05 MPa / 7.25 psi). For high-speed spindles or pressurized housings, contact us to confirm suitability before ordering.

Are these seals compatible with metric shafts and ISO / DIN standards?

Yes. All dimensions (ID × OD × Thickness) are in millimeters and conform to ISO 6194 and DIN 3760 TC-type seal profiles. They are designed as direct metric replacements for OEM seals in gearboxes, pumps, motors, and axles that specify a TC-type metric oil seal.

What equipment are these TC oil seals commonly used in?

Common applications include: automotive rear axle and differential seals, agricultural tractor PTO shaft and gearbox seals, hydraulic pump and motor shaft seals, electric motor end-cap seals, industrial gearbox input/output shaft seals, and marine outboard lower unit seals. Essentially any rotating shaft passing through a stationary housing where lubricant retention is required.

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

1. Clean the housing bore and shaft journal. 2. Lightly lubricate the seal lip with the fluid being sealed (oil or grease). 3. Align the seal squarely with the bore. 4. Press the seal in evenly using a seal driver or a flat plate sized to the OD — never strike the seal face directly with a hammer. 5. Press until the seal sits flush or slightly below the housing face. Avoid cocking the seal during installation, as this is the most common cause of premature lip failure.
