Crimped or pressed connections use special fittings which are permanently attached to tubing with a powered crimper. The fittings, manufactured with a pre-installed sealant, slide over the tubing to be connected. High pressure is used to deform the fitting and compress the sealant against the inner tubing, creating a leakproof seal.
The advantages of this method are durability, speed, neatness, and safety. Some crimped fittings are designed to be used with copper tubing, without requiring flux or filler metal. The connection can be made even when the tubing is wet. Although crimped fittings are suitable for drinking-water pipes and other hot-and-cold systems (including central heating), they are substantially more expensive than sweated fittings.
Pressfittings with either V and M profile (V Contour & M Contour) in stainless steel, carbon steel and copper are highly popular in Europe, and several manufacturers such as, Viega, Gebrit, Swiss Fittings, and ISOTUBI, distribute system dependent press fittings. When compared to other connection types, press fittings has the advantage of installation speed, and safety. Pressing a stainless steel fittings can be completed within 5 seconds with the correct equipment. Major pressing of fittings to pipes or other fittings is completed through electric press machines, however also mechanical press machines are available. Most of the major brands further have a plastic slip on the end of the press fittings allowing a simple identification if a press fittings has securely been installed. Further, the installation does not use any welding, thus press fittings, with appropriate and region specific certification, be installed for gas lines. Stainless steel and carbon steel press fittings can hold up to 16 bars of pressure.
