puristusliitännöistä

Puristusliitännät, known in English as compression fittings or crimp fittings, are mechanical devices used to join two pipes or tubes together. They are a common method in plumbing, gas fitting, and some industrial applications due to their reliability and ease of installation. The fundamental principle involves a nut and a ferrule (or ring) that are compressed onto the pipe ends, creating a watertight or airtight seal.

The process typically involves sliding the nut onto the pipe, followed by the ferrule. The pipe is then inserted into the fitting body, and the nut is tightened. As the nut is tightened, it draws the ferrule down the tapered end of the fitting body, compressing the ferrule against the pipe. This compression deforms the ferrule, creating a tight seal between the pipe and the fitting. The nut then presses the ferrule against the fitting body, securing the connection.

Puristusliitännät offer several advantages. They do not require heat, making them suitable for use near flammable materials or in situations where open flames are prohibited. The installation is generally quick and requires minimal specialized tools, primarily a wrench for tightening the nut. They are also known for their durability and resistance to vibration and pressure changes. However, careful installation is crucial to ensure a proper seal and prevent leaks. The type of puristusliitäntä must also be appropriate for the material and pressure rating of the pipes being joined.
