Apek's first stage, the TEK3, is designed for technical divers to suit their specific needs and developed specifically for use on a twin cylinder.
TEK3 is based on the proven construction of the first stage of the Apeks membrane. It is designed specifically for a dual rear cylinder configuration to meet the specific piping requirements of the first stages.
All ports are placed flush so that the hoses connected to them extend from the first stage in only one direction.
TEK3 is available in two versions - left and right. The first steps allow maximum access to the valves.
