Miflex High Pressure Gauge Hoses

Our most popular Miflex High Pressure (HP) Gauge hose lengths are:

  • 15 cm (6 inch) long for connecting SPGs to the first stage regulator on deco/stage/pony cylinders, and also air pressure transmitters to first stage regulators on your back cylinder
  • 60 cm (24 inch) long for doubles
  • 60 cm (24 inch) or 75 cm (30 inch) long for singles
  • 80 cm (32 inch) long for consoles

Miflex Heavy Duty (HD) Hoses in Carbon Black Colour
Approved according to the EN250 standard.

  • 7.8 mm Thin — 35% thinner than rubber hoses
  • Lightweight — Half the weight of rubber hoses
  • Electroless nickel-plated brass fittings
  • Factory cleaned and Nitrox ready for use with up to 40% oxygen

Hose Material:

  • Heavy Duty with Graphite Carbon Black colour
  • Outside hose diameter: 7.5 mm
  • Braided nylon exterior layer
  • Working Pressure: 300 bar

The typical HP hose has a 7/16-inch male at the end that screws into the first stage regulator HP port, and a 7/16-inch female at the end that screws on to the SPG.

Male Fitting to HP port

  • 7/16 x 20 UNF male threads
  • Brass with electroless nickel plating
  • Strain relief with shock absorber
  • Viton O-ring

Female Fitting to SPG

  • 7/16 x 20 UNF female threads
  • Brass with electroless nickel plating
  • Strain relief with shock absorber
  • 14 mm deep air-spool well

Swivel-Pin Air-Spools — Please note that all high pressure hoses use a swivel pin air spool with two tiny O-rings to mate the swivel connector on the hose to the fitting on the gauge. The airspool is not included with the hose, but we recommend replacing the air-spool when replacing the hose. The standard 'shoulder' air-spool has the flange in the centre. Some SPGs, typically the plastic body ones, may only accept a 'bullet' air-spool without a shoulder. We stock the standard 'long' bullet air-spool as well as the less commonly used 'short' bullet air-spool.
