Zeagle regulators.\n\nConsistently rated a top performer and top pick by Scuba Diving magazine's comparison tests, great factory support with free annual service parts if you buy from an authorized dealer, and dealers such as ScubaToys will match prices from grey market dealers.\n\nOf the Zeagle regulators, I prefer the DS-Vs.  Simple design, environmentally sealed, highly regarded by tech divers (similar to Apeks DS4).

You can use R.O. (Reverse Osmosis) filters.\nThe last filter diameter should be smaller than 0.0001 micron so that stuffs like sugar, herbicide, pesticide,\nsalt, sugar, metal ion cannot get through. \nYou will get purist and healthy water.

do a search on paper companies in your area. many businesses are supplied by them, you may be able to order directly or if you seen a container at your deli for instance, you can order from them. this is a sample of what i'm talking about. if you are talking about glass, then you need a different search.

I would try John Crane Mechanical Seals. They usually can address any type of pump seal or packing question.

If you want the neoprene material itself, do a google search on "custom wetsuits" and look for a small to medium-sized shop that's not too far from you.\n\nA custom wetsuit maker will have many different types & thicknesses of neoprene on hand, and should be able to order even more.  Or check into these sources:\n\nhttp://www.foamorder.com/neoprene.html\nhttp://www.eastexproducts.com/neoprene.htm\nhttp://k-mac-plastics.com/neoprene-sheet.htm
