Features:
1) Easy installation: separated structure makes it very convenient for installation and
dismounting
2) Additional sealing: an additional O-ring seal between the taper of the insert and
the fitting body
3) Corrosion insulation: a thin gasket on the insert serves as an insulation ring,
preventing the bimetallic corrosion between the insert and the aluminum core of the
composition pipe
4) Flexibility: a fitting body can share different inserts, which have the same taper part
but different inner diameters
