TTMA Breakaway Coupling

TTMA breakaway coupling

EWFM supply a safety breakaway coupling specifically for bottom loading arm service. This is designed for bottom loading stations to prevent spillage when a tank truck is moved without disconnecting the API 4″ coupler. This prevents spillage from the hose therefore minimising a fire risk, damage to operators, the environment and equipment.

This coupling is fitted with TTMA flanges at each end therefore allowing close coupling with the API 4″ coupler and the swivel elbow. This TTMA breakaway uses the break stud method of dry disconnect. The coupling has a weight of 4.8kg and within the body it has a seal disc and two valves with pins at either end.

For more other loading arm accessories, please head to the bottom of our loading arm page where you can find a range valves, accessories and signal switches which are all compatible with our loading arms.
