TEK 3 SET, FIRST STAGES

For those that already own two APEKS regulators and would like to take advantage of the TEK 3 first stages, AP0367-1, TEK 3 SET, FIRST STAGES, includes: a LH TEK 3 first stage and a RH TEK 3 first stage in one box. Apeks has developed unique first stages specifically for use on a twinset. The benefits of this system are: minimized 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. The TEK3 utilizes all the proven technology contained within the Apeks range of first stage regulators. The ports on the TEK3 first stages are oriented so that all hoses will route downward to provide the streamlined configuration required by technical divers. Allows unrestricted accessibility to the cylinder valves when using a twin cylinder set up.

Unique over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth. One 7/16" UNF HP ports and three 3/8" UNF MP ports are angled for optimum hose routing. An environmental dry system keeps water out of the main spring chamber thus preventing ice build-up and keeping silt and contamination out. Maximum working pressure is 4350 psi (300 bar).
