Tamper-Resistant Compressed Air Regulators
Prevent unauthorized adjustment and unintentional pressure changes with these regulators. Use them in your air line to adjust and maintain the pressure of your compressed air. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install in your air line after filters.
Regulators with a key lock provide an extra level of security. Set your pressure, lock it, and remove the key to prevent further adjustment. They have a universal lock so you can use the same key for multiple regulators.
For regulators with a T-handle, set your pressure and then remove the T-handle to prevent further adjustment.
Optional pressure gauges are for use with regulators with a T-handle.
Mounting brackets allow you to attach the regulator to a wall or equipment.
