Product Overview

The Hollis 150LX + DC7 pairs an environmentally sealed first stage with a pneumatically balanced second stage, providing a practical starting point for your single-cylinder regulator setup.

The DC7 first stage has fixed hose routing, with four low-pressure ports and two high-pressure ports for connecting your second stages, inflation hoses and pressure gauge. The 150LX second stage includes a dive/pre-dive Venturi lever and an orthodontic mouthpiece for a comfortable fit.

Key Features

  • Over-balanced DC7 first stage: paired with a pneumatically balanced 150LX second stage.

  • Fixed hose routing: four low-pressure ports and two high-pressure ports provide connection options for your setup.

  • Dive/pre-dive Venturi lever: features a soft rubber grip for straightforward operation.

  • Stainless steel details: the second-stage front ring, packing nut and end cap are made from 316 stainless steel.
