Reftekk offers products that promote leak free, reproducible results efficiently and cost-effectively on commercial and residential copper piping systems.

Traditional ACR type L copper and fittings are expensive, labor intensive, and finding skilled tradesman is at a premium. Poorly installed piping leads to costly compressor failures and potentially dangerous system leaks.

Watch the video below to see why the top contractors are switching to Reftekk.

Most traditional copper piping installations in the U.S. are time-consuming and require highly skilled labor.

Standard type L copper tubing in the U.S. cannot be bent – it can shatter and create micro fractures, leading to leaks and system deficiencies down the road – leading to an abundance of joints and fittings.

The rest of the world has already adopted semi-hard, bendable copper and it’s already in 90% of the VRF installations around the world.

Reftekk Cooper Piping

The Reftekk bendable copper tubing comes in the following sizes: 1/4”, 3/8”, 1/2”, 5/8”, 3/4”, 7/8”, 1-1/8”, 1-3/8”, and 1-5/8”. All copper tubing options come standard in 19-feet length to fit into 20-foot containers, and the ends are plugged to prevent dirt from getting in the tubes.

Reftekk uses half-hard tubing that meets all U.S. codes and is 14% stronger* than the hard tube offered by other manufacturers.

Reftekk's Products Save Time and Money


Digi-Bender is a special tool that makes bending Reftekk piping easy, fast, and accurate right at the job site. The Digi-Bender is user-friendly and with Reftekk's Bend Designer App, all angles and bend designs can be easily programed right on the app to assist in mistake free bending. After that, just pull the trigger and let the machine do the rest.

The Reftekk Digi-Bender can be used to field-bend Soft (O60) and Half-Hard (H55) ACR-L copper tubing and transforms hours of experienced labor into an effortless one-man project. Review the Digi-Bender submittal here to learn more.

The Reftekk Digi Bender parts
  • Bends the most common ACR type-L copper tube sizes.
  • Digi-Bender back former sizes include 5/8" - 1-3/8".

Reftekk created the Swage-X, with a 9-sided head that perfectly expands the ends of any bendable copper tubing section in seconds. The Reftekk Swage-X stops on it's own when the optimal expansion is reached. Review the Swage-X submittal here to learn more.

Swage Expander Tools
  • Eliminates the need for copper fittings.
  • Reduces number of brazes by up to half.
  • Creates Proper Brazing Socket.
  • Swages ACR Type-L Copper.
  • Swages Sizes: 3/8" - 1-5/8”.

Brazing Rings

Reftekk takes the guess work out of brazing. With Reftekk precision brazing rings, the only work needed is to braze the top of the socket and within seconds, the silver covering will appear, which is the sign that brazing is done. No hassle and no guessing.

Reftekk saves up to 75% of the time spent in brazing with products from other manufacturers. Less brazing means a reduction in purging and heat that is applied to the system, leaving you with a much cleaner inside pipe.

Reftekk saves you up to 75% of the time you would spend in brazing with products from other manufacturers.
  • No over heating due to noticeable visual cue.
  • Can be used in swaged sockets and regular fittings.
  • Guaranteed full depth penetration.
  • Reduces brazing material.
  • Fewer leaks.  
The Reftekk ACR Brazing Rings come in the following sizes: 3/8”, 1/2”, 5/8”, 3/4”, 7/8”, 1-1/8”, 1-3/8”, and 1-5/8”.​

Insulation and Accessories

EPDM Insulation

EPDM line sets with 1” and 1-1/2” thickness is required by the IECC codes in nearly all states. EPDM is required on all hot gas lines as it is high temperature closed cell elastomeric foam and will withstand the hot VRF temperatures of 248F. Standard insulation (NBR) will fail at these temperatures.

EPDM InsulationReftekk has the best solution in EDPM insulation for VRF/VRV.Reftekk standard and split insulation options are safe and exist to avoid unnecessary headaches.
  • Specifically required by several VRF/VRV MFGs.
  • Exceeds VRF/VRV MFGs 248 Fahrenheit degrees operating temperature requirement.
  • Available in thickness to meet strict energy codes.
  • Available on line sets, as well as pre-split, non-split, elbows, and tees.
  • ASTM E84 (25/50) compliant
  • Ozone Resistant
  • Non-Polar, repels moisture

Cush-A-Therm Supports

The Reftekk Cush-A-Therm is a rigid insulating pipe support that resists compressing or crushing from active-piping system loads.​

Cush-A-Therm Supports
  • Proper Tubing Mount
  • Fire Response
  • Water Vapor Barrier
  • UV and Weather Resistant
  • Prevents Condensation
  • Easy to Install

Refrigerant Ball Valves

Refrigerant Ball Valves

Reftekk offers refrigerant ball valves with an optional EPDM insulation jacket in sizes ranging from a 1/4” to 1-5/8”.

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

There is a schrader valve built into the brass body of the refrigerant ball valve for easy access.

The valve has a maximum working pressure of 700 psig and a working temperature range from -40F to 300F (-40C to 150C).​ EPDM jackets are rated up to 257F.
