ABSTRACT:
A threaded packer (40) is inserted into a first enlarged end (52) of an expansion tube (31). Driver dogs (50) on the threaded packer (40) mesh with dog recesses (54) on the expansion tube (31). The threaded packer (40) and the expansion connection (31) are then threaded onto an outlet pipe (30) on a water meter (10) to interconnect the meter (10) to an inlet (26) and outlet pipe (28). By securely holding the meter (10) the expansion tube (31) may be turned away from the tube (31) with a wrench (70), which forces the packer (40) into the tube (31). By forcing the packer (40) into the tube (31), the tube (31) is pushed into the inlet and outlet butt compression joints creating fluid tight joints. A case (37) is then installed over the expansion connection (32) and is secured in place with a locking pin (68 ) and a locking bar (67).
