Miflex Xtreme LP Regulator Hoses


Miflex Xtreme specialist scuba diving low pressure (LP) regulator hoses are available in over 150 colour, length and fitting combinations from 15 cm long to 210 cm long in ten different colours. The Italian manufactured Miflex Xtreme regulator hoses feature an external polyester safety braiding designed to resist the snags and abrasions that divers can often encounter. Unlike traditional rubber hoses, the double braiding is not simply pushed over the hose fittings. Instead, the braiding is tightly bound and fixed to the hose core by the sleeve. The result is performance and durability in extreme situations. All Miflex Xtreme LP regulator hoses are Nitrox Ready as they come Oxygen Cleaned from the factory.

The flexibility of the Miflex Xtreme regulator hose makes the second stage more comfortable in the mouth and results in smoother hose routing, particularly with long hoses. Available in lengths ranging from 10 cm (4 inch) to 210 cm (84 inch). These low-pressure hoses are great for stage/deco bottles, and we offer the 120 cm (48 inch) length commonly used for stage/deco and octopus hoses in your choice of ten colours: Black, Carbon Black, Blue, Red, White, Yellow, Mellow Yellow, Pink, Green and Purple.

Typical LP regulator hoses, including Miflex Xtreme LP regulator hoses, have a 3/8-inch UNF Male fitting at the end that screws into the first stage regulator LP port, and a 9/16-inch UNF Female fitting at the end that screws on to the second stage regulator.

Choosing the Best LP Regulator Hose Length

"Standard" Setup: The most common hose lengths found on 'standard' primary 2nd stage SCUBA regulator setups (the one on the black hose that's typically in your mouth) is 71 cm (28 inch) or 75 cm (30 inch). The most common hose length found on the 'standard' "Octopus" 2nd stage SCUBA regulator setups (the one on the yellow hose that's typically clipped off or in an occy holder) is 90 cm (36 inch), though some people prefer a longer 100 cm (40 inch) hose length.

For many divers, the "standard" primary 2nd stage SCUBA hose length is too long and will cause the hose to "bow out", and create unnecessary drag and tug on the mouth. This makes for an uncomfortable dive, particularly in current. Some experienced divers and instructors choose the slightly shorter hose lengths of 56 cm (22 inch), 60 cm (24 inch) or 65 cm (26 inch), feeling it is more comfortable with less drag and pull.

Experienced Diver / Streamlined Setup: *** Recommended *** Increasingly we see experienced single tank divers using a 100 cm (40 inch) to 150 cm (60 inch) in length, primary 2nd stage SCUBA LP regulator hose routed under their arm with the regulator on a 20/70/110° or 90° swivel (we prefer the 20/70/110° swivel). We also prefer the 'in-between' 120 cm (48 inch) hose length. Experienced divers figure this is the hose that their buddy will grab, or they will donate, in an emergency, thus it should be the longer hose and black, neon yellow, or yellow in colour. They use a shorter 56 cm (22 inch), 60 cm (24 inch) or 65 cm (26 inch) (we prefer the 65 cm) in length, black coloured LP regulator hose for the backup/octopus 2nd stage regulator they will end up breathing from. In this setup, the backup/octopus regulator is typically hung on a necklace directly below the diver's chin.

Stage Setup: The 100 cm (40 inch) length hose is the common choice for technical diving stage, pony and deco regulators. Different hose colours are often used to make it easier to identify which hose is attached to which breathing gas cylinder.

Long Hoses: Many advanced divers and instructors believe the common hose lengths are too short in out-of-air situations and now use a much longer hose, often 150 cm (60 inch) for those who dive open water exclusively. Many technical divers have adopted a length of 210 cm (84 inch) for overhead environments.

Choosing Your Colour Scheme

With so many colour choices in the Miflex Xtreme low-pressure regulator and inflator/jacket/BC hose line up you are free to create your own unique colour scheme.

Technical divers always donate their longer hose primary 2nd stage regulator, and usually don't colour code either regulator. For sport diving with a streamlined configuration, we still prefer the cover of the primary second stage to be black and the cover of the backup (octopus) second stage to be yellow.

For many years the dive industry has supplied the primary 2nd stage regulator coloured black on a short black hose, and the backup/octopus 2nd stage regulator coloured yellow on a longer yellow hose. Most regulator sets still come like this. This setup is based on the notion that in an emergency you will donate your backup/octopus regulator with the yellow cover and hose to your dive buddy.

Training agencies are now realising that this isn't what happens in real life and are starting to teach accordingly. In real life, in an emergency your dive buddy will rip the primary regulator you're breathing from out of your mouth. Your buddy will thus be on a short hose, and you'll be going for your backup/octopus regulator. Not an ideal situation. Thus the training agencies are now suggesting you should have a long hose on your primary 2nd stage regulator, and a short hose on the backup/octopus 2nd stage regulator you'll be switching to.

For this Experienced Diver / Streamlined Setup we suggest the long hose attached to your primary 2nd stage regulator should be coloured Fluro Yellow or Mellow Yellow. The short hose attached to your backup/octopus 2nd stage regulator should be Black or Carbon Black. But you can also use whatever colour choice you prefer for either hose.

If you stick with the traditional (old fashioned) setup, then the cover and hose for your short hose, primary 2nd stage regulator would be coloured Black or Carbon Black. The cover and long hose of your backup/octopus 2nd stage regulator should be Fluro Yellow or Mellow Yellow. But again, you can also use whatever other colour choices you prefer for either hose.

For stage/deco/pony cylinders we suggest using a Green coloured regulator hose for 90+ percent Oxygen mixes. As for gas mixes greater than 21% and less than 90%, we'd suggest using a Fluro Yellow or Mellow Yellow hose, but just take your pick from the many colours available.

Depth: 1 m (3.28 ft) to 6 m (20 ft)

Level: Open Water and beyond.

The Williamstown Beach Rotunda diving and snorkelling site is located off the Esplanade, Williamstown at the eastern end of Williamstown Beach, and the northern end of Port Phillip. It has an easy beach entry and exit and there are lots of critters to see. It's also close to the Melbourne CBD and while fascinating during the day, also makes for a pleasant night dive.

Williamstown Beach is backed by the Esplanade, making it a very accessible beach. The Williamstown Beach Rotunda is located at the eastern end just west of the breakwater. The beach is 550 metres long and faces due south. It receives waves during strong southerlies.

Proceed from the car park down onto the beach and enter the water just west of the groyne. Head south-west out past Point Johnson until you get to 4 to 5 metres of water depth. Then head south-east for a timed period which will take you across quite a few small reefs down to 5 to 6 metres. Return on a timed reciprocal course. Exit back onto the beach.

There is plenty of boat traffic here so stay away from the surface if you hear a boat coming. Always tow a float with a dive flag. Beware of fishing lines from fisherman that cast off from the groyne (breakwater). Always take a dive knife and/or line cutter.

Parking: You can park at the eastern end of Williamstown Beach in the Williamstown Rotunda Car Park on the Esplanade between Garden Street and Giffard Street. Parking is metered so make sure you get a ticket. There is also roadside parking along the Esplanade. Of course, getting a car park is problematic on busy days in Summer. Before gearing up check out the water. If you see lots of white water, head on home.

Facilities: There are plenty of public toilets, cafe and BBQ facilities nearby.

Warning: Always go with a buddy and carry a dive knife. Make sure you tow a dive buoy with dive flag.

Entry/Exit: Shore beach entry at the eastern end of Williamstown Beach, in front of the shelter, west of the groyne.

Ideal Conditions: There is little background swell in this part of Port Phillip — the water is calm when the wind is still. In moderate winds the waves are choppy and under 0.5 metre. Best with light to moderate offshore northerly to easterly winds, or light onshore south-easterly to north-westerly winds. Not diveable in strong southerly winds. Avoid after rains due to the rain runoff reducing viability. Though the high tide is ideal, you are able to dive at Williamstown Beach Rotunda on any tide. See WillyWeather (Williamstown Beach) as a guide for the tide times and the height of the tide.

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.
