American Tech Supply has in stock a complete Line of Innerduct accesories including Plastic Couplings, Plastic Couplers, Aluminum Couplers, External Couplers, and External Innerduct Couplers. The right hand/left hand reverse thread aluminum couplings are our most economical and versatile coupling for polyethylene innerduct. The couplings work equally well for smooth wall, corrugated, or ribbed type innerduct, and are made in all sizes of SDR and SIDR rated innerducts from 3/4" to 6". Thread-on couplings can be installed by hand or with one of manual or hydraulic powered coupling presses. The sharp buttress type threads withstand high pulling loads that meet or exceed the Bellcore tensile standard of 1000 lbs. Innerduct couplers as also known as innerduct couplings.

These couplings are machined with one degree of taper and have a long chamfered lead-in for straight, easy starting. The couplings incorporate a wide, six pitch thread angle which greatly reduces the number of revolutions necessary to install the couplings. These versatile couplings can be used in manholes, direct bury, aerial, or any application except where an air or water tight connection is required. Custom options, such as multiple colors per reel and Slit Duct, are also available.

E-Loc®couplings feature a strong PVC outer shell with a flexible elastomer inner sleeve.-More Info

The Double E-Loc® coupling was developed for joining both smooth and ribbed HDPE duct, specifically for pneumatic methods of cable placement.-More Info

PNA still manufactures the standby favorite left/right threaded aluminum couplings. They install easily with a pipe wrench, requiring no special tools or equipment.More Info


Machined from tool-grade aluminum, and easily installed with a pipe wrench. Insert duct in both ends of coupling and rotate coupling in direction of arrow. Ducts will be drawn into coupling from both ends at the same time.More Info

The exclusive DuctLok™ Compression Coupler Tool is used to install DuctLok™ Couplings which provide totally airtight and watertight joints that will not separate under normal installation. More Info

As a result of new fiber placement methods and technology, couplings for HDPE innerduct have become an increasingly important component in building today's vast fiberoptic networks. This website details Cabletec's current line of machined and molded couplings. Each of the products represents a user-tested solution to some problem related to connecting innerduct faster, easier and better.

We believe our current line and inventory of standard and specialty couplings is the largest, most carefully engineered, and most competitively priced of any domestic manufacturer. We manufacture couplings in a size range form ¾" to 6" in a wide variety of materials including aluminum, polyethylene, PVC and engineered type plastics. Our production and stocking program is tailored to provide next day delivery on most products.

Our computerized controlled threading equipment that our manufacturer uses gives us the flexibility to produce short runs or specialty couplings with the same efficiency as our standard products. The tempered 6061-T6 tube that we use for our aluminum couplings is extruded from custom dies to a machine-ready size. This eliminates waste of raw material, increases production output and allows us to maintain coupling walls that won't crush or deform.

In designing a coupling, we not only consider how easy it will start to thread an how much it will hold, but what its true in-place cost will be to the end user. The wide pitch thread we use in our reverse thread couplings, for example, allows the couplings to be threaded on with half the rotations in half the time as some competitive couplings. Design features like these save time and money at every connection.

This series of aluminum air tight couplings incorporates the same reliable, full circumference seal used in our barbed ring compression couplings. But unlike other one piece plastic or aluminum compression couplings that have to be installed with some type of coupling press, our multiple lead barbed ring coupling can be installed like any ordinary reverse thread coupling.

Instead of a coupling press, a special wide pitch, fast traveling thread is used to force the innerduct over the barbed ring seal. From a user's standpoint, the coupling would be installed exactly like any common reverse thread coupling except the installation time is shortened by as much as 75% over conventional couplings. Due to the wide pitch angle of the multiple lead thread, only 5 complete turns are required to install these couplings compared to 12 to 15 turns for conventional couplings. Another important feature of the coupling is that the outside diameters are small enough to allow these couplings to be pulled into primary ducts or through plow chutes.

These threaded couplings permit tensil loading as high as conventional reverse couplings and provide a positive reliable seal up to 280 lbs. psi. Being a machined product, these couplings can be sized for the exact outside diameter of any innerduct. The amount of interference designed into the fit of the coupling will accommodate the .012-.015 manufacturing tolerances allowed in the outside diameter of the innerduct.

Anodized Aluminum Couplers- Available in a variety of sizes!

Pricing Starts at $ 5.00 each for quantity purchases

Anodized aluminum reverse-threaded couplers
designed for use with any of the many innerduct
or PE conduit types.

- Air-tight for pressurized cable propulsion systems
- Reverse threaded
- Designed for smoothwall, ribbed, or corrugated duct

Compression Coupling:
Reround HDPE. Sizes 1 1/4" to 6"

High Compression Coupling:
Ideal for Blowing fiber or proofing duct. Sizes 1" to 2

Aluminum Couplings:
Reversed thread couplers. Sizes 3/4" to 4"

Installation Instructions:

  1. Use an innerduct cutting tool to cut the ends of the innerduct squarely. The cut at the end of the innerduct should be at a 90 degree angle to the innerduct wall.

  2. Shove both ends of the innerduct into the coupler so that the innerduct wall is as parallel as possible to the ridges on the outside wall of the coupler.

  3. Turn the coupler in the direction of the arrow on the coupler label using a strap wrench, vice grip, or similar tool.

  4. Tighten to 100~150 foot-pounds of torque
