EW Fuel Management Ltd supply a TTMA 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.
The model 4222 TTMA breakaway 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.
