087314 BAF-E4 Barnes 4" Non-Sparking Moveable Break Away Fitting

087314 BAF-E4 Barnes Pump Accessory 4" Non-Sparking Moveable Break Away Fitting. 

The pump bolts to the bronze moveable portion which is free to ride up and down the guide rails. An O-Ring is pressed into a dovetailed groove on the tapered face of the moveable. The tapered faces of the moveable and base elbow allow for a positive mating of the O-Ring to base. This elastomer to cast iron contact assures a complete and positive seal which allows pumps to operate without hydraulic leakage, over wide range of discharge pressures. These mating parts also allow a Non-Sparking joint which is required in Hazardous Locations.
