## Long description

KAN-therm plumbing bypass 18×18 mm model 620194.3 is a compact bypass fitting designed for hydronic heating and plumbing systems with 18 mm connections. The component provides an alternate flow path that allows balancing, flushing or temporary redirection of fluid without shutting down the main circuit. It is intended for domestic and light commercial installations where reliable bypass capability is required in radial or manifold-mounted pipe runs.
Advantages
The bypass enables uninterrupted operation of the primary circuit while permitting isolation, maintenance or flushing of secondary branches. Its 18×18 mm connection size matches standard small-diameter hydronic piping, ensuring straightforward integration into existing manifolds or distributors. The fitting is compact and engineered for stable flow control, reducing the need for complex workarounds during system servicing.
Suitable for
Balancing and bypassing radiators or underfloor heating loops with 18 mm piping
Temporary diversion of flow during flushing or chemical treatment of a branch
Maintenance tasks that require isolation of a section without stopping the entire system
Domestic and light commercial hydronic circuits with compatible 18 mm connections
Key specifications
Connection dimensions: 18×18 mm
Application: bypass for hydronic heating and plumbing circuits
Material: corrosion-resistant fitting materials suitable for potable and heating systems
Mounting: inline installation within distribution manifolds or branch lines
Function: permits alternate flow path for balancing, flushing and maintenance
How to use
Install the bypass inline between the supply and return lines or across the branch that requires bypassing, ensuring secure connections to the 18 mm pipes. Use appropriate fittings and sealing methods compatible with the system material. Operate the bypass valve or passage to divert flow when balancing, flushing or servicing a section; after work is complete, restore the normal flow path and verify system pressure and leak-tightness. Follow local plumbing codes and standard installation practices for hydronic systems.
Usage recommendations
Confirm compatibility of pipe material and connection method before installation. During commissioning and after any maintenance, check for correct flow balance and the absence of leaks. For systems with chemical treatments or high temperatures, verify material suitability and service limits according to applicable standards.
