Oil Seal Cross Reference Chart: Quickly Match National, SKF, NOK & OEM Seals

Struggling to find an oil seal without a clear part number or dealing with a discontinued model? You’re not alone—maintenance delays can quickly become costly. Our Oil Seal Cross Reference Chart helps distributors, engineers, and importers quickly find exact replacements from brands like National, SKF, NOK, Toyota, Mitsubishi, and more.

Here’s a deep dive into using oil seal cross-reference effectively, ensuring your equipment stays running smoothly with accurate, quick replacements.

What is an Oil Seal Cross Reference Chart?

Ever held an old, unmarked oil seal and had no idea how to find a replacement? This is exactly what a cross-reference chart solves. It’s a database that matches oil seal part numbers, sizes, types, and materials between different brands—like National, SKF, NOK, CFW, and major automotive OEMs (Toyota, Mitsubishi, Iveco).

At Hengoseal, we’ve helped global clients easily replace discontinued or hard-to-find oil seals, keeping operations on schedule and under budget.

How Do I Cross-Reference a Discontinued Oil Seal?

Discontinued oil seal? Don’t panic. Follow these simple steps:

• Step 1: Measure dimensions—Inner Diameter (ID), Outer Diameter (OD), and Width.
• Step 2: Identify seal type (single lip, double lip, with dust lip).
• Step 3: Note your application (motor, gearbox, crankshaft).
• Step 4: Use our Oil Seal Cross Reference Chart (Downloadable PDF) or send us the details directly.

We’ll swiftly identify and recommend the closest match, like our popular TG4 or TC oil seals.

Can I Use an SKF Seal Instead of National?

Yes, as long as crucial specifications match precisely (size, material, type). Our cross-reference ensures accurate equivalents among major brands. Whether replacing National with SKF or vice versa, you’re covered.

Here’s a practical example:
