what can you do with more expensive one that cant be done with the cheaper one?
Use 3A (Triclover) Sanitary fittings. These are very nice in the sense that they have no threads to hide and nurture bacteria hence they are widely used in the brewing, wine, dairy, pharmaceutical and similar industries but as the prices on the 2 units show they are expensive relative to the more normal IPT fittings (they are made of 300 series stainless). They also connect and disconnect quickly without the need for wrenches and can usually, in the small sizes, be connected liquid tight with no tools. They are joined by means of a clamp which encircles the two fittings and is secured by a screw with wing nut. Were you to go this route you would obviously need at least one mating fitting and a gasket (this fits into a groove cut into the flat part of the connector and it is this gasket that actually makes the seal). The mating fitting would have to be Triclover to barb or Triclover to IPT i.e. it has to adapt between the Triclover system and whatever you are using. These adapters are sold by lots of dealers such as Cole Parmer (the place to go if you are trying to get rid of excess money) at one extreme, McMaster Carr in the middle and St. Pats at the lower end of the price scale. If you are in a situation where you connect and disconnect a lot of hoses e.g. you have mash pumps, wort pumps, chillers, filters etc. and need to do it quickly Triclover fittings are great. For a typical home brewing situation I really don't see it for something as small as 14 gallons. There is, however, a definite "cool" factor here.
