MaxiPro Reducer – Reliability in Air Conditioning and Refrigeration Systems
This MaxiPro compression reducer fitting, with dimensions 7/8" x 1/2", is a key element in air conditioning and refrigeration installations. Made of high-quality copper, it provides a durable and tight connection for pipes of different diameters. It is a press-fit fitting, which means quick and reliable installation, minimizing the risk of leaks.
Design and Application
The MaxiPro reducer is used to change the diameter of pipes in refrigerant installations. Its design based on socket connections (crimping and push-in) guarantees resistance to high pressures – up to 48 bar. This makes it ideal for working with various refrigerants, such as R-1234yf, R-32 or R-410A (a complete list of compatible refrigerants is available in the technical documentation). The use of copper UNS C12200 (min. 99.9% Cu) ensures corrosion resistance and long-term reliability.
Advantages for the installer and end-user
- Quick installation: The press-fit system significantly reduces installation time compared to traditional connection methods.
- Tightness: Provides a hermetic connection, eliminating the risk of refrigerant leaks – which translates to energy efficiency and minimizes operating costs.
- Durability: Maximum working pressure of 48 bar guarantees safe operation even in demanding conditions.
- Compatibility: Can be used with various types of pipes meeting the standards PN-EN 12735-1, PN-EN 12735-2 or ASTM-B280.
- Compliance with standards: Meets the requirements of the European Pressure Equipment Directive PED 2014/68/EU, confirming its safety and quality.
- Versatility: A wide range of diameters (from 1/4" to 1 3/8" and from 6 to 28 mm) allows the fitting to be adapted to different installation configurations.
This fitting is a solid solution for both professionals involved in the installation of air conditioning and refrigeration systems, and for end-users who value reliability and long-lasting system performance.
