FAQ
- A blowdown or vent port so you can bleed the gauge to zero before removal, lockable handle for safety-critical lines, NACE/MR-0175 compliance for sour service, a packing material rated for your process temperature, and a body material that matches the line. Cheap gauge cocks often fail at the worst time - spend a few extra dollars for one rated for the actual service.
