Bendable Copper Piping Solutions

Virtually Eliminate Leaks and Reduce Brazing by 75%

Turn those slim margin projects into healthy profit makers

Traditional stick copper and fittings are costly, cumbersome, and finding a fast, skilled pipe-fitter to run your piping is getting harder and harder. Not only that, improperly designed tubing results in very costly compressor failures and potentially hazardous system leaks. Selling profitable piping work is becoming increasingly difficult.

For these reasons, Reftekk was created.

All existing U.S. market piping solutions are time-consuming and require highly skilled labor.


There are two major reasons. First, traditional type L copper tubing can not be bent. If it is, it can break down and create micro-fractures, leading to leaks and catastrophic system vulnerabilities. Therefore, U.S. piping systems require an excess of joints and fittings, which leads us to the second reason.

When you purchase a fitting in the U.S., you have to waste valuable time heating the copper, apply brazing rod around the joint, and hope you’ve sealed the connection when it's all is said and done.

What if I told you that the rest of the world has already adopted semi-hard, bendable copper and that it's now in 90% of the world's VRF installations?

Bendable copper piping and tools from Reftekk are the perfect solution to eliminate up to 75% of your brazed joints, reducing your labor and material costs significantly.

You protect your system from additional sources of leakage with less brazes. At least two brazed joints are saved by each fitting you avoid. That's a huge difference across the whole system.

Bendable copper tubing from Reftekk comes in the following sizes: 1/4, "3/8," 1/2, "5/8," 3/4, "7/8," 1-1/8, "1-3/8," 1-5/8 "and 2-1/8". "All options for copper tubing come standard in 19-foot lengths to fit in 20-foot containers, and the ends are sealed to prevent dirt from entering the tubes.

Reftekk uses semi-hard tubing that follows all U.S. standards and is 10% stronger than other manufacturers' stick copper.

Reftekk is so easy to work with that almost anyone can use it, even if they've never touched a copper pipe in their life.


With Digi Bender, Bend Piping Like a Pro

With Digi Bender Bend Piping Like a Pro

Digi Bender is a special tool (only for use with Reftekk copper) for easy, fast and accurate bending of Reftekk piping right on the job site. The tool is lightweight, user-friendly, and the bend designer software allows you to program all the angles right on your phone. Then you just mark your bend points, pull the trigger and let the machine do the rest.

The Reftekk Digi Bender can be used for field-bending ACR-L copper tubing Soft (O60) and Half-Hard (H55) and transforms hours of experienced labor into a one-man effortless project.

The use of a tubing bender offers many benefits, including fewer brazes, lower risk of leakage and pressure drops, greater flexibility of installation, and no need for costly elbow fittings.

  • Make accurate bends easily: The Digi-Bender allows you to pre-set the desired bend angle using the digital LED screen and scroll wheel, resulting in a precise and repeatable bend with each use – and bend angles up to 190 degrees.
  • Eliminate the cost of installing elbow fittings: Store-bought elbows are no longer needed with the capacity of field-bending tubing on the fly.
  • Reduce the risk of leaks: In a single stick of copper tubing, several bends can be made, and each field-bent elbow eliminates 2 brazes associated with conventional elbow fittings.
  • Proper bend radius: The back-former bend radii were designed to keep the resulting tube elongation well below the minimum manufactured copper tube elongation specification of 25% for Half-Hard (H55).
  • Bends the most frequently used tube sizes: Included are 5/8, “3/4,” 7/8, “1-1/8″ and 1-3/8” back-formers and bending shoes.


With Swage X, perfect fittings and low material cost

Swagers are widely used devices for soldering, but are not ideal for brazing. The "six-pie" shape available in the market on the head of the swagers creates a depth in the pipes that is too deep for brazing, increasing leakage chances.

That's because brazing isn't a filler, it's just a weld. You need a snug fit with no holes while you braze.

That's why Reftekk developed the Swage X with a 9-sided head that correctly stretches the ends of the bendable segment of Reftekk copper tubing in seconds. Even better: when the maximum expansion is achieved, the machine knows and stops by itself, freeing you from the stress of determining the correct size.

  • Eliminates the need for copper fittings: The Reftekk Swage Expander allows installers to create brazing sockets at the ends of any bendable quality copper tube sections when used with a proper bending tool, eliminating the need for elbows and couplings that reduce material costs.
  • Reduces brazes by up to 75%: When used in conjunction with Reftekk bendable copper tubing, the Reftekk Swage X allows sealing of each joint with only one braze instead of the two brazes associated with conventionally brazed fittings. This lowers labor and brazing material costs while increasing the system’s leakage potential significantly.
  • Proper Brazing Tolerance: Creates brazing sockets with tight tolerances, leading to better capillary action and less voids, reducing the potential for leakage.
  • Proper Brazing Socket Depth: The only device on the market designed to produce the required swage depth for brazing (per ASME B16.50-2013), resulting in a  full braze with less potential for leakage.
  • Swages Reftekk Type L Copper ACR Tube Sizes: Head sizes are available in 3/8, “1/2,” 5/8, “3/4,” 7/8 “1-1/8,” 1-3/8 “and 1-5/8”.


New and Improved Brazing Techniques with Precision Rings

With Reftekk the high skill level is taken out of brazing. With Reftekk precision brazing rings with built in flux, all you have to do is braze the top of the socket and in seconds you will see the silver cover, which is the indication that your brazing has been finished. No stress, no guessing.

Reftekk saves you up to 75% of the time you'd spend with other manufacturers' brazing products. Less brazing also comes with reduced purging and heat applied to the system, leaving you with an inside pipe much cleaner.

  • Fewer Leaks: Reftekk brazing rings offer high filler penetration in the joint, which reduces the number of voids and leaks compared to hand-fed brazing rod.
  • Repeatable: The brazed joint of Reftekk is clearly complete when the filler protrudes around the outside of the joint’s maximum circumference. It provides the user with a reproducible visual indication of a completed brazed joint.
  • Simple Brazing Process: Before heating, the brazing ring is inserted into the joint, freeing one of the hands of the operator and eliminating the guesswork on how much brazing rod to use.
  • Reduces Brazing Material: For each size connection, pre-formed rings provide the right amount of filler material, eliminating the cost of guesswork and materials.
  • Double Fillets: Fillets form in and out of the brazed joint, indicating full-depth penetration of the filler. This results in a consistently high-quality connection in contrast to the questionable penetration depth when hand-fed with brazing rod.

The Reftekk ACR Brazing Rings come in 3/8”, 1/2”, 5/8”, 3/4”, 7/8”, 1-1/8”, 1-3/8”, and 1-5/8”.


Get Your Insulation Done Right and Protect Yourself from Costly Mistakes

Insulation for piping should be easy, right? I mean, what can go wrong?

Well, there's a lot. Energy codes are becoming more and more stringent, leading to lawsuits and penalties for improper insulation.

When it comes to EDPM insulation for VRF/VRV Reftekk has the best solution.

  • Required by several VRF/VRV MFGs
  • Exceeds VRF/VRV MFGs 248 Fahrenheit degrees operating temperature requirement

  • Easy to Install: For quick and easy installation, Cush-a-Therm features a split-seal and over-lap seal with peel-off adhesives.

Refrigerant Ball Valves


Reftekk offers refrigerant ball valves in sizes from 1/4 "to 2-1/8" with an optional EPDM insulation jacket.

These ball valves accept the same brazing rings as the tubing of the pipe.

The brass body of the refrigerant ball valve is fitted with a schrader valve for easy access.

The valve has 700 psig peak operating pressure and a working temperature range from -40F to 300F (-40C to 150C).
