124 to the annulus 104 collectively defining a second outlet 128 the top sub 126 is coupled to a swivel housing 116 for the index housing 168 at a lower end 130 the coupling of the swivel housing 134 and the top sub 126 provides an upper shoulder 138 at the lower end 136 of the top sub 126 a lower shoulder 140 formed in the swivel housing 116 is spaced apart from the upper shoulder 136 to form an inner recess 142 within which a swivel ring 144 is retained the swivel ring 144 includes at least one indexing pin 146 extending radially into the axial through passage 124 defined by the outer housing 110 while the swivel ring 144 is axially retained by the upper and lower shoulders 138 140 the swivel ring 144 is not rotationally retained to the outer housing 110 thus the swivel ring 144 may rotate within the confines of the upper and lower shoulders 138 140 along a middle portion 150 of the swivel housing 116 a spring housing 152 is coupled thereto a lower portion 154 of the swivel housing 116 protrudes axially within a through bore 156 defined by the spring housing 152 the lower portion 154 of the swivel housing 116 is spaced apart from the corresponding portion of the spring housing 152 such that a small gap 162 is created within this small gap 162 a spring sleeve 162 is coupled to the spring housing 152 as will be explained below the spring sleeve 164 is included primarily to aid in the assembly and disassembly of the jetting tool 100 the spring housing 152 is provided with external threads 120 at.
