Adel Wiggins Flexible Tube Connectors
Surcharge may apply
Adel Wiggins Flexible Tube Connectors, or Wiggins Clamps, provide an ideal method for quickly and
efficiently connecting and sealing two tubes. They are available in aluminum with a stainless two-finger latch,
and are frequently used for vacuum lines, water lines, and turbo intake plumbing. All are qualified to AS1650
and MIL-C-22263 specs., and are tested to greater than 125 psi. operating pressure, at temperatures up to
450º F depending mainly on the o-ring material.
Our Wiggins Coupling Assembly is
comprised of one Clamshell Assembly
(clamp and sleeve), and two Weld Ferrules.
O-rings are not included.
