Euro Joint Connectors
A new type of ball and socket exhaust connector. There are no gaskets to blow out. The compact design does not require bulky exhaust flanges with nuts and bolts. There is no collapsing of the connection joint like with standard muffler clamps. The re-useable clamping mechanism allows for exhaust tubes to be removed and reinstalled again time after time. This can be used to replace commonly leaky header collector joints, or at most connection points of exhaust products. The ball and socket fitting is sealed tight with the clamp, and this also allows for a little bit of an angle to be put into the connection if needed. Available in aluminized steel or 304 stainless steel, with 2-1/2″ and 3″ size joints in both ID and OD options. We can make other sizes not listed here, including reducing to 2″, or mixing ID and OD options and mixing sizes, just call for special sizes. One joint contains both the male and female portion of the ball joint assembly and one clamp.
