Clamps to quickly and easily connect QF Duct Pipe.

The Quick-Fit (QF) Clamp provides quick and easy connections for QF Duct Pipe. Suggested quantities for QF Clamps are 1 per part. They are are available in 3" - 24" diameters.

Clamps come standard with Nitrile seals and bridge pin for locking clamp into closed position. Other available gasket seal types are Silicone and ePTFE for applications where temperature is not suitable for Nitrile.

Its QF rolled ends for use with these QF clamps, allow quick assembly, disassembly and relocation. It clamps together in seconds without welds, bolts, screws, flanges, special tools, precise measurements or specialized skills. So, it cuts installation – and ducting related downtime – by more than 40% over traditional ductwork. Quick-Fit has been used in a wide variety of applications, wherever dust collection or fine particulate transfer is required.

  • Quick, simple assembly with QF Duct Pipe
  • Gasket comes in Nitrile, Silicone, or ePTFE 

What is the best seal for my application?

Nitrile seals are inserted into QF Clamps as standard. Rated for max. intermittent service temperatures of 194° and continuous 158° F, there is no additional charge for nitrile so it is the most economical choice.

Silicone seals are an economically priced option for operating temperatures above 158° F. Rated for max. service temperature of 400° F, silicone has an extremely broad temperature range capability as it is also very good in low temperatures, remaining flexible at -60° F. Additionally, silicone offers superb resistance to weather aging and ozone.

ePTFE seals are not degraded by any common chemicals (0 - 14 pH range) FOR INDUSTRIAL USE ONLY. Not for use in food, drug, cosmetic or medical device manufacturing, processing, or packaging operations. Max. temperature rating of 600° F

Questions & Answers

Do QF Clamps come with the pipe? If not how many do I need to order?
Clamps do not come with pipe. As a rule, you will need one clamp per component ordered.

When do I need ePTFE seals with clamps?
ePTFE clamps are used in FDA, chemical, and high temperature applications. For higher temperatures, silicone seals may also be used. Please see the seal guide above for temperature ratings.

How do I connect to the end of an existing non QF system?
We offer a full line of adapters to connect to any existing pipe you might have.

When do I need to use stainless steel?
Stainless steel is used in FDA, chemical and high temperature applications.

Nordfab Ducting General Specifications

Nordfab QF duct is a clamp together design using a rolled edge design with a single lever clamp. The ducting and clamps are constructed from similar materials. All clamps contain a standard gasket made of Nitrile which is suitable for most applications, including oil mist, as long as high temperatures are not an issue. Silicone and ePTFE gasket options are available for higher temperature applications. Nordfab Quick-Fit Ducting is available in 1" increments sized 3" to 24" diameter.

Nordfab’s laser welded seam Quick-Fit® Ducting System has been used in many different industrial applications, and under various negative static pressures. The typical design range we see in our applications range from -2" wg to - 28" wg; however, there are some systems operating at vacuums of -32" wg to -42" wg under normal operating parameters.

The pipe comes in 5' lengths with a rolled lip on each end, thus providing reinforcement every 5', which presents a sound structural design that should be as strong or stronger than any pipe in its class according to SMACNA guidelines and regulations.

All fit together ducting systems allow for some degree of leakage where they are joined. QF® Ducting is no exception and is not sold as an airtight system. In comparison to other ducting typically used in fit-together systems, Nordfab’s QF duct pipe has fully welded, leak-tight laser or plasma welded seams. Spiral and other ducting with lockform seams are not fully welded at the pipe seams and can be expected to have higher leakage rates than QF duct.
