The first stage from Apeks, TEK3 has been designed for technical divers to best suit their specific needs.

TEK3 is based on the proven construction of Apeks membrane sealed first stages. It is designed specifically for a dual cylinder configuration - double-mount - to meet specific hose routing requirements from the first stages.

The TEK3 has three medium pressure 3/8 "UNF ports and one high pressure 7/16" UNF port. All ports are located flush so that the hoses connected to them extend from the first stage in one direction.

TEK3 is available in two versions - left and right. The first stages are connected to the valves by outer diaphragms facing each other, allowing maximum access to the valves.

NITROX TEK3 will also be available with both DIN and M26 DIN standards.

Of course there is a DS (Dry Sealed) system known from closed first stages of Apeks.

The weight of one TEK3 first stage is 0.7kg.
