BS ISO 3601-1 Aerospace size O-rings

Aerospace O-ring sizes to BS ISO 3601-1

The sizes and tolerances for Aerospace applications differ to those specified within BS ISO 3601-1 for general industrial (ie, non-Aerospace) applications, as covered in our Chart 50.

BS ISO 3601-1 O-rings for Aerospace applications use housings identified in BS EN 3748 Aerospace series O-ring grooves: Dimensions.
