Understanding Oil Seals: What They Do, How They Are Measured & Common Brands

Oil seals are one of the most important components in machinery, vehicles and industrial equipment. Even though they are small parts, they play a major role in protecting machines from leaks, contamination and costly damage.

At Perkins Seals, we understand how important it is to get the right seal for the right application. Here’s a simple guide to understanding oil seals.

⸻

🔧 What Does an Oil Seal Do?

An oil seal is designed to:

✔ Prevent oil or grease leakage
✔ Keep dust, water and dirt out
✔ Protect moving components such as shafts and bearings
✔ Maintain pressure and lubrication inside machinery

Oil seals are commonly used in:

* Vehicles
* Gearboxes
* Hydraulic systems
* Pumps
* Mining equipment
* Industrial machinery
* Agricultural equipment

Without a good oil seal, machinery can lose lubrication, overheat, wear out faster or even fail completely.

⸻

📏 How Are Oil Seals Measured?

Oil seals are usually measured using three main dimensions:

1️⃣ Inner Diameter (ID)

This is the shaft size — the inside measurement of the seal.

2️⃣ Outer Diameter (OD)

This is the housing or bore size — the outside measurement of the seal.

3️⃣ Width / Thickness

This is how thick the seal is.

⸻

Example:

35 x 52 x 7

This means:

* 35mm = Inner Diameter
* 52mm = Outer Diameter
* 7mm = Width

Measurements can be in metric (mm) or imperial (inches) depending on the machinery.

⸻

🧱 Common Oil Seal Materials

Different applications require different seal materials. Some common materials include:

🔴 Nitrile Rubber (NBR)

The most common material.
Good for:

* Oil resistance
* General industrial use
* Standard temperatures

🔵 Viton (FKM)

A stronger, premium material.
Best for:

* High temperatures
* Chemicals
* Heavy-duty applications

⚫ Silicone

Used where flexibility and temperature resistance are important.

🟤 Polyurethane (PU)

Very durable and commonly used in hydraulic applications.

⸻

🏭 Common Oil Seal Brands

There are many seal brands on the market, but some are known for their quality and reliability.

⭐ SOG

One of the most recognized brands in the industry.

SOG seals are known for:
✔ Durability
✔ Precision fit
✔ Good resistance to wear
✔ Reliable performance in automotive and industrial applications

Because of their consistency and quality, many customers specifically request SOG seals for vehicles, pumps and industrial machinery.

⸻

Other Common Brands

* NOK
* SKF
* TTO
* Corteco
* National
* NAK

Each brand may vary slightly in:

* Rubber quality
* Lip design
* Spring tension
* Durability

That’s why choosing the correct brand and specification matters.

⸻

⚠ Why Correct Sizing Is Important

Using the wrong size or incorrect material can cause:

❌ Oil leaks
❌ Premature wear
❌ Overheating
❌ Shaft damage
❌ Machine downtime

Always make sure:
✔ Measurements are correct
✔ Material matches the application
✔ The seal is properly installed
