Derek Smith
40mm x 50mm x 8mm U-Cup Hydraulic Seal
Excellent service

Tried the local stores and couldn’t get the seals that I wanted. Most online retailers wanted to sell me hundreds of different sized seals - most would have ended up in the bin.

TotallySeals provided exactly what I needed, delivered quickly and communicated extremely well.

What is a Nitrile O-Ring?

A synthetic rubber material that is extremely versatile, nitrile (NBR) is used for seals due to its ability to resist common chemicals including petrol, oil, acid and alkalines. This makes it the perfect choice for automotive components, as it is usually used for fuel tanks components and any other seals that are constantly in direct contact with fuel.

Nitrile is also perfect for medical devices, as it causes less allergic reactions to common substances such as latex and rubber.

Why use a Nitrile O-Ring?

Nitrile (NBR) O-Rings are popular for their durability, especially in applications requiring resistance to oils, fuels, and certain chemicals. They offer a reliable, cost-effective sealing solution for various industries, including automotive, aerospace, and manufacturing. With excellent wear resistance and the ability to handle temperatures from -40°C to +120°C, Nitrile O-Rings ensure a long-lasting, secure seal in demanding environments.

How do I choose the right size o-ring?

To select the correct size Nitrile O-Ring, start by measuring the internal diameter (ID), outer diameter (OD), and cross-sectional thickness. These measurements will help you determine a proper fit, ensuring an effective seal. It’s essential to consider factors like pressure, temperature, and the type of material it will come into contact with, as these can impact the performance and longevity of the O-Ring. For guidance on specific sizes or custom requirements, refer to our size charts or reach out to our team for assistance.
