Slip Fitting vs Flange Connecting System

Is One Really Better Than the Other?

Slip fitting vs Flange connecting systemFlange connections provide a stronger joint, improve durability, and save labor during installation!

When it comes to HVAC installation, there are two main ways to improve your profit margin: cutting material and/or labor costs.

In considering your project, it's important to understand these areas do not stand alone.

Your materials can directly affect labor costs, and unless inventory is chosen wisely, any savings in material can easily be eaten up by labor.

This relationship becomes clear when you consider traditional slip couplings vs. modern flange connecting systems.

Flange connecting systems offer as much as 50% time savings compared to other systems!

You know from experience, traditional slip couplings and reducers are simply clumsy to work with, and that means expensive 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 becomes a significant problem for ductwork 30" and more in diameter.

When major contracts are involved, why risk installing a product that may perform below industry standards?

This is Where Flanged Systems Excel

What if we told you that flanged connecting systems improve the joint strength, seal, rigidity, and hanging strength of the entire ductwork structure AND save money at the same time? This is exactly what flange connecting systems like AccuFlange™ from Spinfinity achieve.

AccuFlange™ was designed with one overriding goal: to save field labor.

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 more information:

When the pipe size is 30" or larger, ZEN Industries recommends the use of a flange connecting system.

Flange connections not only provide a stronger joint, improving the durability of the entire system, but most importantly save up to 50% labor time during installation.

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