Sealing hydraulic fittings

Use of Teflon and sealants for sealing joints made ​​of brass hydraulic fittings

The GNALI BOCIA catalogue has a dedicated section providing a complete range of generic threaded hydraulic fittings which are necessary for hot and cold water installations, both for domestic use and for heating. The machining accuracy and reliability also allow their use in gas installations. 
Made of brass CW617N or CW614N, the hydraulic fittings contemplate models like the classic female-female elbow joint or the male-female one which is always useful, a complete range of straight figures, such as the threaded cylinder, the nipples, the reducers, sleeves and plugs. .. tees complete the offer. 
The most frequently used hydraulic fittings are in sizes ranging from 3/8 "up to 2" which are those commonly used in both the domestic and industrial sector. 
However, in order to ensure a watertight seal, the threaded connection needs material placed on the threads to help to seal the thread. Teflon tape is usually used for sealing hydraulic fittings, as this is crushed into the threads during tightening thus avoiding leaks and ensuring the connection is airtight. In more recent times, specific liquid sealants have also been created that solidify once applied and locked into the fitting, thus generating the necessary seal. These have been specifically created in order to prevent damaging and degrading the material of the fittings.
