Safety Extension Couplings & Locking Collars

The Locking Collar for ACME Fittings is designed to provide an extra layer of security by locking onto the hex portion of an ACME adapter. This prevents loosening due to twisting and vibration of ammonia hoses between the nurse trailer and toolbar. 

• Easy Installation & Removal: Equipped with a retractable spring, it locks in place quickly as you thread on the extension coupler and removes effortlessly by pulling back the collar when you need to disconnect the hose. 
• Fits Most Standard ACME Fittings: 134AL connects to 1-3/4” ACME, and 214AL fits 2-1/4” ACME fittings.
• Locking Collar available on it's own or with safety extension coupling.
