Port Plugs and Dust Caps


We carry an assortment of Replacement Port Plugs and Dust Caps for SCUBA Regulators which are interchangeable and compatible regardless of brand.

We offer 3 sizes of port plugs... but most regulators only have 2 size plugs on their first stages. Port plugs can be either a high pressure (HP) port plug or a low pressure (LP) port plug.

The most common size port plug for LP ports (BC inflator hoses, Regulator hoses) is the 3/8" size. This size is used on most brands of regulator made around the world. A few brands of first stages have a larger size low pressure port that is 1/2-inch, notably some older Apex and Aqualung models.

The most common size port plug for the HP ports (SPG, air integrated computers, transmitters) is the 7/16" size. There are a few unique regulators available that use a larger size high pressure port size of 1/2". This 1/2" size is not common and are usually found on Apeks, Mares and old Dacor regulators.

The LP 3/8" port plugs use the 4mm Hex key.
The HP 7/16" port plugs use the 5mm Hex key.
The HP 1/2" port plugs use the 5mm Hex key.

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.



Refuge Cove, North Wall

Wall Dive Wall Dive | Boat access Boat access

Ideal For Snorkelling Marine Park - No Fishing Open Water Rated Reef Dive Site Wilsons Promontory

Depth: 5 m (16 ft) to 20 m (66 ft)

Level: Open Water and beyond.

Refuge Cove, North Wall, on the eastern side of Wilsons Promontory, is suitable for both snorkelling and scuba diving. It has boulders sloping down to a sandy bottom at a depth of 14 metres. Refuge Cove, North Wall lies in the Wilsons Promontory Marine Park facing south-east into Bass Strait. There are groups of boulders forming, swim throughs, caves, and overhangs.

Refuge Cove, as the name implies, offers protection and refuge from the ocean. For 200 years, sailors and boaters have used this cove to escape the hazards of Bass Strait and as a safe and attractive anchorage. The entrance to the cove is 400 m wide and opens up inside to reach 1 km across. The cove is surrounded by steep forested slopes, rising to 200–300 m. A walking track connects the cove with Sealers Cove to the north and Waterloo Bay to the south. A camping area is located behind the southern beach. Refuge Cove houses two sandy beaches; both composed of pure, rounded, yellow quartz grains. The coarse quartz and low waves produce steep beach faces and deep water close to shore. The cove is therefore ideal for boat anchorage. The northern beach faces south-east toward the entrance, while the smaller southern beach faces due north, and is the preferred anchorage. Dense vegetation grows right to the back of the beach, with the camping area located under the trees. A creek cuts through the vegetation and across the eastern end of the beach.

Diving and Snorkelling at Refuge Cove, North Wall

The north wall of refuge Cove is an easy dive but certainly not boring. There are numerous boulders covered in kelp offering swim throughs and large quantities of marine life. It's not uncommon to see schools of Bait Fish being followed by schools of Salmon. Other fish including Blue Throat Wrasse, Long Nose Boarfish and Barber Perch are also present and in large numbers.

The best way to see this site is to be dropped off at the point of the cove and swim west into the cove itself.

The site is sheltered from most wind conditions even when easterlies prevent diving elsewhere. However, it can be prone to surge during an easterly swell.

Ideal Conditions: Refuge Cove, North Wall is best dived with calm seas, no swell and no wind. Light offshore north-westterly to northerly winds may be acceptable. Avoid strong onshore north-easterly to southerly winds. See WillyWeather (Refuge Cove) as a guide for the tide times and the height of the tide.

Bass Strait Warning: Always keep an eye on sea conditions throughout any shore or boat dive in Bass Strait on Victoria's coastline. Please read the warnings on the web page diving-in-bass-strait before diving or snorkelling this site.

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.
