Each first stage has three medium pressure ports and one high-pressure port. They are over-balanced, cold water compatible, and extremely robust. TEK 3 looks great too. Not only is the TEK 3 suitable for twinset use but it is equally suitable for single cylinder or stage cylinder configurations offering perfect, snag-free hose positioning.
