Union coupling male 40 1 1/4

A union coupling (often called a union or "amerikanka") is a professional plumbing fitting designed for easy connection and disconnection of pipes in water supply and heating systems. Its primary advantage is the ability to install and maintain piping systems without the need for cutting pipes. The fitting ensures a leak-proof seal, pressure resistance, and durability. Available in a wide range of sizes (from 20 mm to 63 mm) with both female (V/R) and male (N/R) threads.
