Frequently Asked Questions

Q: What material are these O-rings made from, and why does it matter?

A: These O-rings are made from NBR (Nitrile Butadiene Rubber), a synthetic rubber known for its excellent resistance to petroleum-based oils, hydraulic fluids, fuels, and a wide range of liquid and gas media. This makes NBR nitrile O-rings ideal for use in automotive, industrial, and mechanical sealing applications where exposure to oils and chemicals is common.

Q: What cross-section (CS) thickness options are available?

A: These NBR nitrile rubber O-ring gaskets are available in 1.5mm and 5.3mm cross-section (CS) thickness options. Please select your required size at the time of purchase to ensure the correct fit for your application.

Q: Are these O-rings suitable for both static and dynamic sealing applications?

A: Yes. These standard nitrile O-ring gaskets are engineered to perform reliably in both static (stationary) and dynamic (moving) sealing environments, making them versatile for use across machine tools, automotive systems, hydraulic equipment, and more.

Q: How do I know which O-ring size I need?

A: To select the correct O-ring, measure the inner diameter (ID) of the groove and the cross-section (CS) depth. Match these measurements to the available size options. These rings come in complete, standard specifications to cover a broad range of common sealing requirements.
