Conex Bänninger >B< MaxiPro Reducing Coupler

A flame-free reducing press coupler from the Conex Bänninger >B< MaxiPro range, for joining two imperial (inch) refrigeration-grade copper tubes of different sizes on air conditioning, heat pump and refrigeration pipework. Both ends are press sockets, so it joins tube to tube directly. Pressing replaces brazing, so there is no hot work, no nitrogen purge and no fire risk on site. Sold individually.

Key points

• Copper reducing coupler with press sockets both ends (tube x tube)
• Maximum operating pressure 48 bar (700 psi), suitable for high-pressure refrigerants such as R32 and R410A (see the MaxiPro refrigerants table for the full approved list)
• Operating temperature -40°C to +120°C
• HNBR sealing O-ring
• No flame, brazing or hot-work permit needed

1 x MaxiPro reducing coupler in the size selected.

Specification and prices

Options

Currently available in 5/8" x 3/8" from our Lincoln stock. The first figure is the larger tube end, the second the smaller. To reduce directly out of another MaxiPro fitting, use a MaxiPro fitting reducer instead.

Installation and compliance

MaxiPro fittings must be pressed with a MaxiPro-approved press tool and the correct MaxiPro jaws; check the tool compatibility information in the technical brochure before use. Tube must be clean, deburred, fully inserted and marked to the correct insertion depth, as set out in the installation instructions. Work on refrigerant circuits must be carried out by an F-Gas certified engineer, and the system pressure and leak tested before charging.
