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 100% 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.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Always check the validity of information with local authorities, especially in regards to restrictions of diving in the area. As information on this dive site database is obtained through multiple sources, the accuracy of the information cannot be guarunteed. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source, e.g. GPS, Google Earth, or unknown.

If you don't understand the differences between the different ways coordinates are given, plus how different datum come into play, you might find the article GPS Conversions by Lloyd Borrett a useful read. It describes the problems associated with locating dive sites using a GPS receiver.
