#CMT# #/CMT# The plug (1), to seal water pipe connection openings while the system is tested, has an outer thread (2) with a length (L) at least equal to the outer diameter (D1). The thread section extends from a flange (3), with a recess (4) on the side towards the thread to take a ring seal (7) projecting (A) from the flange surface. The free end (5) of the plug, away from the flange, is shaped to be used by a tool. A further outer thread (6) is between the flange and the free end. #CMT#USE : #/CMT# The plug is used to seal connection openings in water pipes, in buildings, when they are tested for sealing by passing water through at high pressures. #CMT#ADVANTAGE : #/CMT# The plug is easily handled to seal the connection openings and can also be used to assist in installing the fittings. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the plug. 1 : plug 2,6 : outer threads 3 : flange 4 : recess 7 : ring seal A : seal projection D1 : thread diameter L : thread length. |
