Flange drilling with BS4504 EN1092 or ANSI Standard
GD8.8,stainless steel bolts nuts and washers
various coating
Seal:NBR ,EPDM etc
Precaution
Aquagrip flange adaptor can’t accommodate for AC(Asbestos cement) pipe and GRP pipe.Because AC pipe surface is too rough ,the griper of aquagrip flange adaptor can’t work properly.GRP pipe is very smooth, can’t offer enough friction for the griper.

Use
Both ends can connect pipes with the same outer diameter or different outer diameters at the same time, as long as the design range of Mechanical Coupling Joint includes the outer diameter of the pipes
