Fuel rails

Helium leak test

Leak testing systems for fuel rails

Detect leaks from fuel rails using helium in a vacuum chamber

The helium test as a dry method is ideal for checking fuel rails. The fuel rails are tested at high pressures of > 200 bar and a relatively low permissible leakage rate. An efficient helium recovery system completes the device.
