Radiator distributor Comap 1/2–M22 universal with adjustable outlet (MPN 916422)

Comap radiator distributor compatible with 1/2–M22 connections, universal with an adjustable outlet, designed for use in hydronic heating systems. The compact distributor is intended to route and control flow to individual radiator circuits, providing manual adjustment of outlet flow for balancing and commissioning. It is suitable for installations in residential and light commercial manifolds where a small, adjustable distributor is required.

Advantages

The universal 1/2–M22 connection ensures compatibility with common radiator fittings and simplifies replacement or retrofit work. The adjustable outlet allows precise manual control of flow to individual radiators, aiding hydraulic balancing and enabling straightforward commissioning without specialized tools. Its compact design facilitates installation in confined manifold cabinets and reduces the need for additional adapters. Manufactured to meet typical plumbing and heating installation expectations, the distributor provides reliable mechanical operation for radiator circuits.

Suitable for

• Domestic radiator manifolds in single- and multi-family homes
• Light commercial radiator installations where compact distributors are required
• Retrofit projects replacing or upgrading existing radiator outlets
• Hydronic systems requiring manual flow adjustment for balancing

Key specifications

• Connection compatibility: 1/2–M22 standard radiator fittings
• Outlet type: adjustable manual outlet for flow control
• Design: compact, universal distributor body suitable for manifold integration
• Application: intended for hydronic heating radiator circuits

How to use

Install the distributor in the radiator manifold following standard plumbing and heating practices and local regulations. Connect the inlet and return lines using compatible 1/2–M22 fittings and ensure seals and threads are correctly engaged. Adjust the outlet manually to set the desired flow to the radiator circuit; use a flowmeter or temperature-based method during system commissioning to achieve hydraulic balance. Verify there are no leaks after pressurizing the system and re-check settings after the system reaches normal operating temperature.

Usage recommendations

Perform installation and adjustment work with the heating system depressurized and cooled. Use appropriate sealing materials compatible with the system fluid and follow local codes. For precise balancing, combine manual outlet adjustment with flow measurement or radiator temperature differentials. Periodically inspect connections and the adjustable mechanism for corrosion or wear, especially in systems with aggressive water chemistry or high cycle frequency.
