Puristuspäät

Puristuspäät, often translated as "compression fittings" or "press fittings" in English, are a type of pipe joint used in plumbing and heating systems. They offer a method for connecting pipes without the need for soldering or welding, making them a popular choice for both professional installers and DIY enthusiasts. The principle behind a puristuspää is mechanical force. A fitting, typically made of brass, copper, or plastic, contains a sealing element, usually an O-ring, and a clamping mechanism. When the fitting is attached to the pipe ends, a specialized tool is used to compress the fitting, forcing the pipe into the seal and creating a watertight connection.

The installation process is generally straightforward. The pipe ends are cut squarely, deburred, and then inserted into the puristuspää. The tool then applies pressure to the fitting's collar, permanently deforming it and securing the pipe. This deformation creates a strong and reliable joint that can withstand significant pressure and temperature variations. Different types of tools exist, often specific to the size and type of fitting being used. The advantages of using puristuspäät include speed of installation, reduced risk of fire hazards compared to soldering, and a clean, professional-looking finish. They are commonly found in water supply lines, heating systems, and gas installations, though specific applications may require fittings approved for those uses. Maintenance of puristuspäät systems typically involves periodic checks for leaks, especially after initial installation.
