Slip Fittings vs. Flange Connecting Systems

Slip Fittings vs. Flange CouplingsWhich do you need? And, which is best for your installation?

You know from experience, traditional slip couplings and reducers are simply clumsy to work with, and that means unnecessary labor time.

Slip fittings have several additional drawbacks. With a coupler, joint strength resists pulling and compression, but does little for rigidity and hanging strength. This weakness is multiplied for ductwork 30" and more in diameter.

To improve the joint strength, seal, rigidity, and hanging strength of the entire ductwork structure AND save money, you need to look to a flange connecting system. At ZEN, we work with the AccuFlange™ system from Spinfinity.

According to Spinfinity, AccuFlange™ was designed with one overriding goal: to save field labor. Actual time studies reveal savings up to 50% compared to other systems.
Available for both round and oval duct, flanges fit inside the ductwork and are screwed or tack welded to the spiral itself, with a butyl gasket providing the seal. Double wall can be handled the same way, with the flange engineered to have two rings, allowing various thicknesses of liner to go in between.

For joining round and oval ductwork, including double wall spiral, when the pipe size is 30" or larger, ZEN Industries recommends the use of a flange connecting system.

At ZEN Industries, we're constantly pushing the envelope with regard to estimating efficiencies, quality HVAC ductwork, and on-time, on-budget delivery.

Retrofitting Commercial HVAC Equipment

Roof Curb for HVAC InstallationWhen installing HVAC roof top equipment, new units often come with roof curbs, or have curbs offered as an accessory.

However, when removing an old roof top unit for retrofit, these accessory roof curbs prove incompatible with the existing curb, vent positions, and roof penetrations.

At ZEN Industries, we fabricate customized curb adapters to make your roof top unit retrofit go smoothly, providing a weather-tight seal along with the durability and cost-effectiveness you're looking for.

In addition to precision customization, at ZEN we understand the need to have your order expedited (delivered yesterday if possible). From your first call to ZEN customer service through the process of ordering and delivery, you'll recognize the difference ZEN brings to the table.

  • Roof curb adapters made to your precise specification
