About 1/2" Male to 3/8" Female Regulator Adapter

Some regulators have 1/2" Ports on the first-stage for high-flow hoses, but all dive resorts usually carry only the minimum in spare parts, so don't lose out on a vacation dive because you now need to hunt the entire island for the right size hose. This adapter will get you out of trouble in a pinch. Adapter threads into your regulators high-flow port reducing it to a standard 3/8" port in a second. Adapter is made of marine grade chrome plated brass for long life and durability. At times, you can never find the one you need. That is, unless your source is Leisure Pro.

Questions about this item:

Shopper  Why Did You Choose This?
Matt F  Purchased to convert 2 older US Divers- ProDiver series Regulators- S/N beginning with R2A and S2A- Units have 4x 1/2 ports. All new LP hoses come with 3/8 connectors... so it seems. This will make all regulators the same.
Randy M  further to my first question I found the shipping rate thanks but would still like to known if this is the right adapter the hose from the reg is 1/2 and the adapter goes in the first stage and this is 3/8? R.T. Melnick
BOB H  No , your going large to small........This is small to large 3/8 female/inside/id (inside diameter) to 1/2 male/outside/od (outside diameter).....sounds like you want the reverse
Shopper  How much pressure will this support?
FRANCISCO N  Probably alot because its made of steel so in fact the important thing is how much pressure can the hose take.Your 2nd stage and Octo's and Bc inflators are all low pressure like 350 Psi ,Your gauges are on High Pressure Port oviously alot more pressure this adapter should work on both ports but check with your DiveShop. So your hoses are things that pop sometimes so I recommend to replace them new every 2 to 3 years
