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

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.

Eastern Maar country
Eastern Maar country

Traditional Owners — This dive site is in the traditional Country of the Eastern Maar people of south-western Victoria between the Shaw and Eumerella Rivers and from Yambuk in the south to beyond Lake Linlithgow in the north. This truly ancient Country extends as far north as Ararat and encompasses the coastal townships of Port Fairy in the west, Warrnambool, Peterborough, Port Campbell, Apollo Bay, Lorne, and Airies Inlet in the east, including the Great Ocean Road area. It also stretches 100 metres out to sea from low tide and therefore includes the iconic Twelve Apostles. "Eastern Maar" is a name adopted by the people who identify as Maar, Eastern Gunditjmara, Tjap Wurrung, Peek Whurrong, Kirrae Whurrung, Kuurn Kopan Noot and/or Yarro waetch (Tooram Tribe) amongst others. We wish to acknowledge the Eastern Maar as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. 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 of GPS, Google Earth, or unknown.
