Apeks has developed unique first stages specifically for use on a twinset. The benefits of thissystem are that there is a minimised risk of accidental snagging, no hose kinking and easier access to the manifold valves. Each first stage has three medium pressure ports and one high pressure port. They are over-balanced, cold water compatible and extremely robust. TEK3 looks great too! Not only is the TEK3 suitable for twinset use but it is equally suitable for single cylinder or stage cylinder configurations – offering perfect, snag-free hose positioning.
