This Trieste J regulator was given a new life by way of FX precut cans, new gray silicone diaphragm, one way valves, hoses, mouthpiece and a total rebuild complete with new parts including high pressure seat.  This regulator is awesome as you have a nice two stage balanced regulator with the mechanical advantage of a larger diaphragm and two low pressure and one high pressure ports (all ports are 3/8).  These are very rare and I don't come by them very often so if you want a vintage style reg with all the ports and new silicone goods, this is for you.

Price $500.00 plus 17.00 shipping.
