Valve Recommendation

Edited: 5/11/2005 1:57:18 PM by lascrew

I need to replace my 8 Serai valves, which have become crap.
I'm looking for the best recommendations for replacements. I want something to handle high pressure. When i replace them I'm also purchasing an Oasis XD2000 and I'm planning to upgrade all my lines to Hydraulic lines (which someone recommended for handling high pressure).

Does anyone know of a on-line source for hydraulic lines for this type of application? This is the first I've heard of this option.

TIA
