Safety Extension Coupling, 1-1/4" MNPT x 1-3/4" Female ACME

Continental NH3 Products boasts one of the market leading products when it comes to NH3 locking collars for acme fittings. When the unit is engaged, it locks onto the hex portion of the acme adapter. This prevents the acme coupling from loosening due to twisting or vibration. These units are available in 1" or 1-1/4" pipe thread couplings with 1-3/4" acme fittings. It easily locks onto most standard acme fittings and can be mated onto any 1" or 1-1/4" anhydrous ammonia valve.

The spring-loaded locking collar keeps the unit securely in place while it is in use and easily retracts when the valve is not needed. If you have ever witnessed a valve work itself free in the field, thus sending a cloud of ammonia into the air – you know the value of this product. There is no longer a need to torque down a fitting and flatten gaskets while trying to ensure the connection stays tight during field operation. Virtually eliminate the concern of a coupling loosing due to vibration. Give it a try today – you won't be disappointed.
