Meter Size Adapter Bushing Set - Change 5/8" x 1/2" meter to 3/4" Meter Threads (A12)


  • $17.00

Up-size the 1/2" Meter threads on a 5/8" x 1/2" meter to 3/4" meter Threads

These bushing thread onto a 5/8" x 1/2" meter to allow it to fit in a 5/8" x 3/4" meter setter, or fit 3/4" meter couplings.

  • One PAIR of lead-free brass water meter adapter bushings (1 lot of 2 bushing). This item sold only as pairs.
  • Inside female threads fit the 1/2" meter threads of a 5/8" (5/8" x 1/2") Water Meter (approximately 1" O.D. meter spud).
  • Outside threads are 3/4" AWWA Spec meter threads to fit 3/4" meter couplings (approximately 1-1/4" I.D. meter coupling nut).
  • Allows a 5/8" (5/8" x 1/2") water meter to be installed in the setting for a 5/8" x 3/4" meter.
  • Does not change the lay length of the water meter (both 5/8" and 5/8" x 3/4" meters are 7-1/2" long).
  • Fits 3/4" meter coupling (female) swivel union nuts using 3/4" meter gaskets.
  • This set essentially turns a 5/8 x 1/2 water meter into a 5/8 x 3/4 water meter when installed.
  • The Length of the bushing is 5/8".

Note: These are AWWA spec straight meter threads, not NPT standard pipe threads, so they won't work for other typical plumbing applications.

Directions: Thread onto 5/8" water meter threads until the outer face is even with the meter spud end. Insert 3/4" meter gasket in 3/4" meter coupling and tighten until gasket seals. The meter coupling gasket seals against the end of the meter, not the threads. (Thread sealant is never used on water meter threads. The watertight seal is made by the compressed meter coupling gasket between the and swivel nut and meter spud end).
