QF Ball Joint
The QF Ball Joints allow for up to 22° of movement off center. This makes a good fit for systems that have machines with moving dust ports. They are manufactured with Galvanized Steel only, in 4 to 14” diameter, 20, 18, 16, 14ga., and in lengths of 4.5 to 17.5”, all based on the diameter.

The Quick Fit Ball Joints allow for up to 22 degrees of movement off center. This makes a good fit for systems that have machines with moving dust ports.
QF Ball Joints are manufactured as follows:
- In 4 to 14 inch diameters, with 20, 18, 16, or 14 gauge Galvanized Steel only and in lengths of 4.5 to 17.5 inches based on the diameter size.
- The Collars are located on the exterior side of each port and considered as air flow non-directional and have a laser welded longitudinal seam. A raised lap seam and spot weld are used for attaching the collar to the body and no caulking is used
- Standard QF ends can be changed to Raw with a defined ID dimension (RawID), Raw with a defined OD dimension (RawOD), No Fitting or just a raw end (NoFit), Flexible hose adapter (RawFlex), Flat Flange (FFL), Angle Flange (ANGFL), or Van Stone (VanStone).

NOTES:
- At temperatures ranging between 390° F and 480° F, the zinc-iron alloy layers in the galvanized steel will continue to provide a high level of protection from corrosion. However, there may be some peeling, changes in mechanical properties, and reduction in the corrosion protection. Recommended maximum service temperature is 390° F.
- Rock River Silicone Sealant and Red Devil HVAC/R High Temperature Silicone Sealant are not able to be painted.
