  • carl:

    What is the thread specification (3/8" NPT or metric spec.) for the low pressure ports on the Scuba Pro MK25 first stage? Im trying to refit the regulator with a 60 hose between first and second stages for diving under my boat, and I need to buy male and a female port adapters. I want to leave the tank topsides. Thanks.

    Hello, this is a 3/8''s inch port which is the standard low pressure size.

The MK25 teamed with our exceptional new A700, offers superior ultra-high airflow system for maximum performance in all temperatures and diving conditions.
SCUBAPRO is synonymous with piston-controlled first stages. Our MK25 underscores this heritage with an array of patented features and ultra-stable intermediate pressure, for an extremely punctual and consistent high delivery of air.
The MK25 balanced piston first stage is our absolute top performer, making this system our very best.
Air balanced flow-through piston provides constant and effortless air flow unaffected by changing tank pressure.
Newly polished chrome edition, available uniquely with A700 system, with 5 low pressure and 2 high pressure ports plus swiveling turret for convenient arrangement and personalisation of your gear.
Anti-freeze protection for all diving temperatures and externally adjustable intermediate pressure for easy maintenance.
300bar DIN configuration.
