LP 1st Stage Adaptors


The Scuba Doctor offers a large variety of low pressure (LP) first stage regulator port adaptors for recreational, technical, rebreather, sidemount and commercial diving applications.

Most low-pressure hoses are 3/8-inch male and most first stage low-pressure ports are 3/8-inch female. A few brands of first stages have a special low-pressure port that is 1/2-inch female, notably some Apex and older Aqualung models. We offer 1/2-inch to 3/8-inch adaptors.

Reminder: The actual configuration of an adaptor is a mirror image of its use. A 3/8"-24 UNF FEMALE port requires a 3/8"-24 UNF MALE adaptor etc. In technical diving operations where many fittings may get co-mingled, be sure that all adaptor combinations can accommodate the intended flows and pressures.

Looking for a particular fitting you don't see here? Let us know and we'll see if we can order it for you.

We reserve the right to limit order quantities to less than 10 pieces because our supply is appropriate for the demands of individual divers, but not bulk orders. Large volume bulk orders will NOT qualify for our free shipping promotion.



Tyre Reef

Reef Dive Reef Dive | Boat access Boat access

Inside Port Phillip Open Water Rated Reef Dive Site

Depth: 10 m (33 ft)

In 1973, three tyre reefs were placed on the sand relatively close to the shore on the eastern side of Port Phillip. The reefs consisted of 1,000 tyres tied in bundles of eight, quarry rock, concrete cubes and steel frames. Only this Tyre Reef, off Chelsea, remains intact.

The reef is dominated by red algae, sponges, ascidians, and hydroids. Fish include snapper, ling, boarfish, red mullet, beardie and bearded rock cod, leather jacket, long-finned pike, as well as a number of smaller species. This area is popular with fishermen so beware of fishing lines.

Boon Wurrung / Bunurong country
Boon Wurrung / Bunurong country

Traditional Owners — This dive site is in the traditional Country of the Boon Wurrung / Bunurong people of the Kulin Nation. This truly ancient Country includes parts of Port Phillip, from the Werribee River in the north-west, down to Wilson's Promontory in the south-east, including the Mornington Peninsula, French Island and Phillip Island, plus Western Port. We wish to acknowledge the Boon Wurrung as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging. We acknowledge Bunjil the Creator Spirit of this beautiful land, who travels as an eagle, and Waarn, who protects the waterways and travels as a crow, and thank them for continuing to watch over this Country today and beyond.

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.
