Ductmate Gasketed Coupler 4 in 42 in 24 ga

SKU CH-AN2Z-H23NP

Galvanised steel gasketed coupler for 4 in round duct, 42 in long, 24 ga, SMACNA compliant for quick installation

  • Gasketed seal prevents air leaks on round duct runs
  • 42 inch length covers long spans with fewer joints
  • 24 gauge galvanized steel resists corrosion in HVAC systems
  • SMACNA compliant construction meets industry ductwork standards
  • Quick installation design reduces labour time on site

42 in Gasketed Coupler for 4 in Duct

This galvanized steel coupler joins sections of 4 in round duct, light gauge tubing or hose in HVAC systems. The 24 gauge wall provides structural rigidity while the integrated gasket seals the joint without tape or mastic. It meets SMACNA standards for commercial and residential ductwork.

Fits 4 in round duct and light gauge tubing

The coupler slides over the outside of each duct end, so no reducer or transition fitting is required. Its 42 in length bridges longer gaps between trunk lines or equipment connections, reducing the number of joints in a run. The gasketed design eliminates separate sealing steps during assembly.

Replaces non-gasketed slip couplers and taped joints

Installers who currently wrap seams with tape or apply mastic will cut labor time because the gasket seals on contact. The longer 42 in body also replaces multiple shorter couplers joined together, lowering leak points. Builders who need a different diameter or a shorter coupling length should select another size.

Questions about this item

Will the 24 ga galvanized steel hold its shape when the duct runs full pressure all day?

The 24 ga galvanized steel wall resists deformation under normal system pressure and the galvanized coating protects against corrosion during continuous operation.

Does the gasketed joint stay airtight and quiet when the fan runs 24/7?

The factory-applied gasket seals the 4 in duct fitting against leakage and dampens vibration so the connection stays quiet during round-the-clock airflow.

What duct size must I already have for this 42 in coupler to fit?

You need 4 in diameter round duct, light-gauge tubing or hose that matches the 4 in fitting diameter of this coupler.
