A quick reference of some types of sanitary connections found in the industry are illustrated below. There are also John Perry and Q-Line connections; see online catalog for additional information.
 |
 |
| Clamp Connection | Bevel Seat Connection |
 |
 |
| I-Line Connection | Buttweld Connection |
NOTE: Clamp type connections are the most popular and are sometimes referred to as Tri-Clamp connections.
All connections are Tube OD ½" to 12"
Materials are available in 304 and 316L stainless steel, (other alloys can be special order)
Tube Hanger Support Recommendations:
Processing lines are not to be rigidly anchored to equipment. They must be allowed to float. Temperatures can cause expansion and contraction - if tube hanger supports are mounted incorrectly, distortion and possibly leakage of the lines could occur.
Proper Tube Hanger Support Installation:
Straight sections of tube need support every 10 feet. Support needs to be on each side of every valve (as close as possible to the connection). Additionally, a support needs to be at each change of direction.
What the part numbers mean...
| 2 | Elbow (unpolished, polished, clamp, 90, 45, u-bend etc...) |

| 10 | Diaphragm valve * |
| 11 | Plug Valve * |
| 13 | Clamp (single pin, double pin, 3 segment, bolted, I-line, light weight, etc...) |
| 14 | ferrule (short, long, auto weld, tank, roll on, hose adapter, also male for I-line and plain for bevel seat) |
| 15 | ferrule (bevel seat threaded or I-line female) |
| 16 | End Cap (clamp, weld, I-line, bevel, etc...) |
| 17 | Adapter (bevel to clamp, I-line to clamp etc...) |
| 19 | Adapter (tube OD to NPT) |
| 21 | Male adapter (clamp to MPT) |

| 31 | Concentric Reducer (unpolished, polished, clamp, etc...) |
| 32 | Eccentric Reducer (unpolished, polished, clamp, etc...) |
| 38 | Flange |
| 40 | Gasket (1" and above) |
| 42 | Gasket (1/2" and 3/4") |
| 45 | Check Valve (spring, ball, air blow) |
| 51 | Butterfly Valve |
| 60 | Compression Valve * |
Notes:
- * Dixon Sanitary does not offer at this time
- MP in a part number usually means a clamp fitting
- W in part number usually indicates a weld part
- I in a part number usually indicates I-Line fitting
- Bevel seat is tricky...consult literature and cross reference sheet
