Honeywell 45900402 – 041 zatyczka do rur M11x1

This pipe plug, listed under boiler pipes, flanges and connections, is a component used to seal an unused threaded port in a boiler or burner system. Parts of this type close off openings in manifolds, valve bodies, or heat exchanger headers where a connection is not required, preventing leakage of water, gas, or condensate. The thread size M11x1 indicates a metric fine thread. When selecting such a plug, the thread type and size must match the port, and the sealing method—typically a tapered thread or a flat gasket face—must suit the application. The material, usually brass or steel with a suitable coating, and the pressure/temperature rating should be compatible with the system where it is installed. For boiler-specific assemblies, the plug may be part of a connection set designed for a particular model, so the geometry and sealing arrangement are fixed. When replacing a plug of this kind, check that the new one has the same thread dimensions and that the sealing surface is clean and undamaged.
