Apeks TEK3 Right Hand 1st Stage

Apeks has developed unique 1st stages specifically for use on a twinset. TEK3 1st stage regulators are designed for use with twin cylinder configuration. The system benefits from streamlined hoses with little chance of accidental snagging and also improved ease of access to cylinder valves. Each 1st stage has 3 medium pressure ports and one high pressure port. They are balanced, cold water compatible and extremely robust. TEK3 looks great too.

The regulator can be purchased in both a left hand and right hand version to fit both posts of your twinset for optimum hose routing.

The TEK3 can be purchased individually as a left or right hand version or together as a pair. Usually you will find it is cheaper to buy them as a pair. Please see images for the mounted set-up.

Images also show the TEK3 1st stages mounted on a manifold system. You can see how the hoses are neatly tucked away - both high pressure and medium pressure hoses. This is possible as all hoses are mounted on one side of the 1st stage and there is a 1st stage specifically for the left and one for the right.

Another clear benefit for divers is the ease of access to the cylinder valve knobs. Vitally important during dives.

The TEK3 1st stages have been designed and tested for use with any Apeks cold water spec second stages. The choice is yours. We are sure this is a leap forward for extended range diving, wreck diving, cave diving, in fact any diving where twinset use is preferred.

A TEK SET is also available which comprises 2 x TEK3 1st stages, 2 x XTX50 2nd stages, 1 x 2.1 mtr hose and 1 x 1 mtr hose, and a regulator necklace.
