NIBCO PressACR is a fittings and valves system designed for air conditioning and refrigeration applications. The NIBCO PressACR system uses a unique press-to-connect method to join copper tubing without soldering or brazing and support the higher pressure requirements of HVACR systems. The NIBCO PressACR system includes a variety of fittings and valves, such as tees, elbows, couplings, adapters, and valves, all designed to work with copper tubing in both residential and commercial applications.
The press-to-connect method used by the NIBCO PressACR system involves using a press tool to squeeze the fitting onto the copper tubing, creating a secure and leak-free connection. This method can be faster and easier than traditional soldering or brazing methods and can also be used in tight spaces where a torch may not be practical. In addition, the gray HNBR sealing element used in NIBCO PressACR provides permanent leak-proof connections in 1/4" through 1-3/8" OD diameters and is backed by a 15-year warranty.
PressACR fittings are approved for use with K, L, and M hard copper tubing and soft copper tubing in 1/4" through 7/8" OD diameters. In sizes 1-1/8" and above, PressACR is only approved for use with K, L, and M hard copper tubing. All tubing must comply with ASTM B280 ACR tube or B88 standards.
PressACR fittings are approved for air conditioning and refrigeration applications using A class refrigerants. The NIBCO PressACR system provides a reliable and efficient solution for joining copper tubing.

How are PressACR fittings different from standard press fittings?
NIBCO PressACR fittings have several key differences from standard press fittings:
- Material – NIBCO PressACR fittings are made from copper alloy C12200, designed for refrigeration systems. Standard press fittings are made from various materials, including copper, stainless steel, PEX, and carbon steel.
- Design – NIBCO PressACR fittings have a unique design that includes a patented "wave stopper" feature. This feature helps to prevent leaks by creating a tight seal between the fitting and the tubing. They typically have a larger sealing surface area than standard press fittings, which helps to create a more reliable and leak-free connection.
- Compatibility – NIBCO PressACR fittings are specifically designed to work with refrigeration and air conditioning systems, whereas standard press fittings are designed for a variety of applications.
- Higher Pressure Rating – PressACR fittings also often have a higher pressure rating than standard press fittings, as air conditioning and refrigeration systems typically operate at higher pressures.
- Certification – NIBCO PressACR fittings are certified to meet industry standards for refrigeration systems, including ASME B31.5 and ICC-ES PMG-1206. Standard press fittings may or may not meet these standards, depending on the product and manufacturer.
Overall, NIBCO PressACR fittings meet the unique requirements of refrigeration and air conditioning systems and are a reliable and effective option for those applications.
NIBCO PressACR vs. Other Manufacturers' ACR Press Offerings
NIBCO PressACR is one of several brands of ACR press fittings and valves available on the market. Other manufacturers that offer ACR press fittings and valves include Viega, Uponor, and ZoomLock.
One key difference between NIBCO PressACR and other manufacturers' offerings is the specific design of the fittings and valves. Each manufacturer may have a slightly different contour and sealing element to meet the requirements of air conditioning and refrigeration system requirements.
Another difference may be the materials used in the fittings and valves. While most ACR press fittings and valves are made from copper, some manufacturers may use different materials or alloys to meet specific requirements. PressACR fittings are manufactured in the USA from 100% globally-sourced pure copper.
In addition, the availability and range of products offered may vary between manufacturers. For example, some manufacturers may offer a broader range of fittings and valves or have a more extensive distribution network to make their products more widely available.
Finally, manufacturers may vary the pricing of ACR press fittings and valves. Therefore, it's important to compare different brands' prices and quality to determine which offers the best value for your specific needs.
Overall, there are many factors to consider when comparing NIBCO PressACR to other manufacturers' ACR press offerings, including design, materials, availability, and pricing. It's important to do your research and choose a product that meets the requirements of your specific air conditioning and refrigeration application.
