Steel galvanized ball joints provide flexibility in ducts serving moving cutter heads or other moving equipment. This allows the duct to swing through an arc while maintaining exhaust flow in the line. Ball and swivel joints are available in 3" through 12" diameter.
US Duct ball joints will have TWO proper installation collars — one collar to fit ductwork and a second extended collar to connect to the flex hose — allowing for proper and free rotation of the ball joint. Ball joints are a great way to provide an additional solution product to the end-user and marketplace. Providing the manufacturer’s rep or contractor with a reputation of providing solutions and bringing value to their business along with additional profits.
Swivel joints allow for movement between flex hose and duct, or between two pieces of hard duct (link to ducting), but along a 360 degree stationary plane. The joint consists of overlapping duct joined by ball-bearings that provide a reflectively low friction swivel for periodic or constant spinning movement. Swivel joints can connect spiral pipe or flex hose to allow the rotation of a dust or fume hood, making it an ideal solution for CNC router & other machines with traversing heads.
