## Long description

The ARCO COMBI MAC combination valve is a professional-grade plumbing component engineered for precise water flow regulation in residential and commercial water supply systems. This high-quality brass valve features a versatile 1/2" x 3/4" x 3/8" connection configuration, allowing for efficient branching of water lines. Designed with durability in mind, it provides a reliable solution for managing water distribution to multiple fixtures from a single supply point.
Advantages
The primary benefit of the ARCO COMBI MAC is its robust brass construction, which ensures long-term resistance to corrosion and mechanical wear. The valve is designed to withstand high operating pressures up to 16 Bar and temperatures reaching 110°C, making it suitable for demanding plumbing environments. Its 90-degree angle design facilitates space-saving installations in tight areas, while the included nut ensures a secure and leak-proof connection, simplifying the assembly process for professional installers.
Suitable for
Connecting multiple water appliances to a single supply line
Residential kitchen and bathroom plumbing upgrades
Commercial water distribution systems
Systems requiring precise flow control and shut-off capabilities
When it may not be suitable
This valve is not intended for use with gas lines or aggressive chemical fluids that may degrade brass components. It is also not suitable for high-flow industrial applications where the 3/8" outlet diameter would cause excessive pressure drops.
Key specifications
Material: Brass
Connections: 1/2" outer thread, 3/4" external thread, 3/8" nut
Angle: 90 degrees
Maximum operating pressure: 16 Bar
Operating temperature range: 0°C to 110°C
How to use
Installation should be performed by a qualified professional to ensure system integrity. Begin by ensuring the water supply is shut off and the pipes are clean. Apply appropriate thread sealant to the 1/2" and 3/4" connections before threading the valve onto the supply pipe. Use the included nut to secure the 3/8" connection to the secondary appliance line. Once installed, slowly open the supply to check for leaks at all connection points before fully pressurizing the system.
What to consider before purchase
Verify the thread sizes of your existing plumbing infrastructure
Ensure the 3/8" outlet is compatible with your appliance hose
Check that the operating temperature and pressure requirements align with your system
Confirm space availability for a 90-degree valve installation
Usage recommendations: Regularly inspect the valve for signs of mineral buildup or leaks, especially in hard water areas. Ensure the valve is fully accessible for maintenance or emergency shut-off purposes.
