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?
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
Yes this does work but take Reg. and the adapter to your dive shop have them check for leaks there should be none . Most of my old Reg.s are 1/2 in. these little guys came in handy . And most shops want $15. for them . Before you dive have all your gear checked by a pro .
Yes, that is what I used it for, to allow the use of a Mares, which has the larger thread.
I don't think this will work for you, if the end of your hose is too small to screw into the first stage this is the right adapter if the hose is too big to screw into the first stage you need a different hose.
No, this adapter fit into the FIRST STAGE hole 1/2 and accept normal hose with 3/8 thread.
This adapter is for standard 3/8" hose going into a 1/2" port on the first stage. (Will work with some Mares and older Apeks)
If I understand you correctly, your house is1/2 and your regulator is 3/8 this is not the right part. You need 3/8 male to 1/2 female adaptor. The past number is AQUHAA. If you have any question, let me know.
If you are trying to make a 1/2" hose fitting fit into a 3/8" low pressure port, then yes, this is what you need.
