Dynatech® 791-09025 Ball And Socket Kit 2.50

Unlike common metal to metal connections, Dynatech®™s unique 4-Bolt, Ball and Socket connection uses a 0.5" thick, tapered donut gasket, which allows for expansion and contraction while maintaining a long lasting leak free seal. We also use 4 bolts instead of two or three for added durability. For use with any 3.00" O.D. collector and 100% stainless steel.
