FITTING JIG FOR SERVICE TEES STOPPER

PURPOSE:To fit a stopper into service tees even in narrow place by arranging a rotatable tool which is rotatably inserted into a cylindrical main body from the upper side, formed into a hexagon head bolt at the head part, and formed into a hexagonal fitting part to fit into a hexagonal hole formed in the rotary shaft of the stopper at the lower end. CONSTITUTION:When a stopper is fitted to the lower end of a cylindrical main body by utilizing thread, a rotatable tool 4 is pushed by the force of a spring 7 so as to fit the hexagonal fitting part 6 of the extreme end into the hexagonal hole on the stopper side. The cylindrical main body 1 is held in this condition and inserted into service tees, the stopper is put to the inflow port of service tees so as to press the fixed flange 3 of the cylindrical main body 1, the hexagon head bolt 4 formed on the head of the rotatable tool 4 is rotated with a spanner, then the rotary shaft on the stopper side is rotated, the diameter of an elastic body is enlarged so as to make close contact with the inflow port of the service tees and close the port.
