MK17 EVO 2 First Stage

Description

The direct transmitter port takes an adapter out of the stack, which is one fewer o-ring sitting above the tank valve on a rig that already carries plenty. That is a small thing that matters. This is the sealed balanced diaphragm MK17 EVO 2 sold on its own, more compact and lighter than the MK17 EVO it replaces, with a dry ambient pressure chamber and dual diaphragm keeping water and pollutants away from the mechanism entirely. The forged chrome-plated marine-grade brass body carries a rib shaped to improve heat exchange and the dry chamber runs a twin spring layout. Two high pressure ports lie at 15 degrees, four high-flow low pressure ports handle the other side, and intermediate pressure of 9.2 to 9.8 bar adjusts externally, so a technician tunes it without stripping it. Weight is 797 grams in INT 232, and the DIN wheel is a dual-compound design with a soft grip on a black nylon frame. It suits a diver building a set for cold or dirty water.
