Quick-Fit Angle Flange Adapters are fitted with an industry standard Angle flange on one end and a Quick-Fit (QF) rolled edge at the other, allowing quick connection of QF duct pipe or fittings to flanged pipes or fittings. Longitudinal seam is solid welded. Adapter length can be adjusted.
QF Angle Flange Adapters are manufactured as follows:
- In Galvanized or Stainless-steel metal up to 24 inches with a standard 20 to 22 gauge and an optional 18 gauge
- Flanges are floating to allow easy match up to holes on existing Flanges and retained with a 3/8 inch Van Stone Lip
- Angle flanged end can be modified to a 3/16 inch-thick Flat Flange(FFL) if a custom hole pattern is required
Angle Flanged Adapters in heavier gauged galvanized metal are available in the XD line.
- Construction: Longitudinal seam is laser welded.
- Angle Flange can be modified to a 3/16 " thick Flat Flange (FFL) to match your hole pattern.

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.
- For 304 SS metal, bluing may occur at temperatures of 800° F and above.
- Rock River Silicone Sealant and Red Devil HVAC/R High Temperature Silicone Sealant are not able to be painted.
