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.

Pinafore Shipwreck History
The Pinafore was an unregistered wooden steam launch of between three and five tons The vessel was owned at the time of its loss, by Mr G.A. McGowen of Footscray.
Pinafore Sinking — 27 October 1893
While being towed up Port Phillip on a voyage from Western Port to Williamstown by the steam tug Amy, the Pinafore began shipping water when the light northerly breeze freshened to a gale and ran up a strong sea. Bailing was ineffectual, so Captain Wilkins stopped Amy's engines to allow Pinafore's crew, and its master Captain C.T. White, to board for safety.
Just as Pinafore ranged alongside a heavy sea broke over the vessel, causing it to founder head first. The Pinafore was reported to have sunk on 27 October 1893, in 10 fm (18 m) of water, 7–8 miles to the north of the West Channel Pile Light.

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.
