PIPE UNION HOSE TO ABSORBER THERMAL DILATATION AND EV ITAR ELECTROLYSIS.

摘要

Tube connection sleeve to absorb thermal expansion and prevent electrolysis, applicable both in domestic drinking water installations and in heating installations, comprising the following parts made of brass: a hollow cylindrical cartridge (2) inside which Insert a cylindrical and hollow slide (3) that is welded at one of its ends to a pipe (8) and incorporates two O-rings (9) to prevent water leaks and contact between the different pipes (7, 8) and a stop guide (4) located on the bottom of the cartridge (2) that prevents the slide (3) from being able to exit by means of screws (5) that fix the stop guide (4) to the cartridge (2) through the holes (6) of the cartridge (2). The upper end of the cartridge (2) is threaded to another pipe (7), the sleeve absorbing thermal expansion between the pipes (7, 8).
