Elite Sealing Performance
& Industrial Grade HNBR

Defining the gold standard in rubber sealing technology for high-stress environments.

As a leader in the rubber products industry, we provide a high-performance hydrogenated nitrile o ring solution that bridges the gap between NBR and FKM. Our seals offer EXCEPTIONAL HEAT RESISTANCE and superior mechanical strength, ensuring zero leakage in critical automotive and aerospace fluid systems.

Our hydrogenated nitrile o ring is engineered with a proprietary hydrogenation process that optimizes the polymer chain, resulting in ENHANCED OZONE RESISTANCE and prolonged service life. This technical advantage reduces maintenance downtime and operational risks in aggressive chemical environments.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

What makes HNBR superior to standard NBR?

The hydrogenation process removes double bonds in the polymer chain, making the hydrogenated nitrile o ring significantly more resistant to heat, ozone, and oxidative degradation.

02

Can HNBR seals handle biofuels?

Yes, our HNBR compound is specifically formulated to exhibit low swell and high stability when exposed to modern biofuel blends and synthetic oils.

03

What is the typical service temperature?

Depending on the grade, our seals generally perform reliably from -30°C up to continuous operating temperatures of +150°C.

04

Do you offer custom sizes?

Yes, we specialize in custom molding based on your specific drawings, providing micron-precision tailored to your hardware.

05

What is the lead time for samples?

Our rapid prototyping system allows us to deliver custom samples within 7 working days.

06

How are the seals tested for quality?

We utilize a combination of hardness testing, tensile strength analysis, and 100% visual inspection using high-resolution cameras.
