Q. Can O-rings be used at 90 MPa hydrogen pressure?

A. It's depending on the application conditions. Material selection and realistic testing become even more important at these pressure levels.

 - Explanation

At 90 MPa, hydrogen permeation and decompression effects become more severe. Internal blistering and cracking may occur if materials are not properly designed and validated.

Comprehensive evaluation should include pressure cycling, decompression rate, temperature conditions, and seal geometry.

Takaishi Industry conducts high-pressure hydrogen testing, including pressure cycling up to 95 MPa, through specialized hydrogen testing facilities.

 - Takaishi's Comment

For ultra-high-pressure hydrogen applications, test data is essential. We emphasize validation under realistic service conditions to help customers achieve safe and reliable designs.
