The Heavy Duty Swivel Repair Kit includes o-rings, ball bearings, split rings and grease nipple.
Three sizes available. 1/2" NPT, 3/4" NPT and 1" NPT.
Please order according to the size of the threads. The threads are measured in NPT (National Pipe Thread). So a 1/2" super swivel will measure about 3/4", a 3/4" NPT will measure close to 1". For an explanation of NPT, please see this page: http://en.wikipedia.org/wiki/National_pipe_thread.
Swivel not included.
