Puristusliitännät

Puristusliitännät, also known as compression fittings, are a type of mechanical fastener used to join pipes or tubes. They are a popular choice in plumbing and industrial applications due to their ease of installation and reliability. The fundamental principle behind a puristusliitäntä involves a ring, or ferrule, that is compressed onto the pipe when a nut is tightened. This compression creates a watertight seal between the pipe and the fitting body.

There are several types of puristusliitännät, including single-ferrule and double-ferrule designs. Single-ferrule fittings typically use a softer metal ferrule that deforms to create the seal. Double-ferrule fittings employ two ferrules, one that bites into the pipe and another that seals against the fitting body, often offering a more robust and vibration-resistant connection. Materials commonly used for puristusliitännät include brass, stainless steel, and various plastics, chosen based on the application's pressure, temperature, and fluid compatibility requirements.

The installation process for puristusliitännät is generally straightforward. The pipe is inserted into the fitting, and the nut is tightened. As the nut is turned, it pushes the ferrule(s) into the fitting body, creating the seal. This method eliminates the need for soldering or specialized tools, making it a convenient option for both professional installers and DIYers. However, it is crucial to ensure the pipe is clean and properly prepared, and that the correct size fitting is used for optimal performance and to prevent leaks.
