Abstract
A portable cleaning tool (12) for cleaning the bore (38) of a valve (10) comprising a tool fitting or connector (52) with a reduced diameter inner end portion (82) having an O-ring (86) for sealing against an enlarged bore portion (40) of the valve body (18). The conenctor (52) is threaded within the enlarged end bore (44) to engage in abutting relation an internal shoulder (46). The cleaning member (60) is of an enlarged diameter and has a tapered seat (63) adapted for seating in a retracted position on a mating tapered seat (88) of the connector (52) to prevent any blowout of the cleaning member (60). One embodiment shown in FIGS. 5 and 6 has an internally threaded nut (108) threaded onto external mating screw threads (110) on the valve body and engaging a retainer ring (106) on the connector body (53A) for mounting the connector (52A) on the valve (10 A).
