Branch Connections  
In 1943 when Bonney Forge pioneered the "Shape of Reinforcement" for branch connections, who would have thought it would fast become a recognized industry standard. Today, Bonney Forge Branch Connections offer complete run pipe reinforcement while avoiding cracks, fillet welds, and sharp re-entrant corner reinforcement tapering at the sides, thus preventing abrupt changes in thickness where the fitting joins the header pipe.

All Bonney Forge forgings are inspected before leaving the factory, undergoing three separate quality control systems: one for material control, one for manufacturing and one for design control. Branch Connection forgings also undergo frequent checks against mill documents during the manufacturing process to assure the highest compliance with ANSI and ASTM specifications. Plus, comprehensive record keeping of every fitting from initial forging bar through forging, heat treatment, machining, storage and shipment means every fitting is traceable to the exact material and process used in its manufacture.

Flexolet™
Flexolet reduces the number of fitting sizes per outlet made possible by the revisions to the MSS specification. This means less warehouse bin locations, fewer individual inventory items and less time needed for filling orders.

Flexolet’s Straight Thru Bore design allows for easy clean up of any base welding penetrating into the I.D. bore by grinding, etc. Flexolet is available in threaded, butt-weld and socket weld fittings.
