Needed adapter for old type 1st stage high pressure port, this item fit the bill perfectly.

 

Perfect Fit

By Ryan M.

Fit perfectly and was shipped quick????

Still diving with that old regulator? Did your 3/8" pressure gauge hose die and you can't find a 3/8" replacement hose? Don't retire your trusted pal just because all pressure gauges now have 7/16" hoses. This adapter is just the item you need to prolong the life of your trusty old regulator. Adapter has 3/8" male threaded end that will fit your older model first-stage with 7/16" female to accept the new HP hose standard. Adapter is made of marine chrome plated brass for strength and durability and comes with standard HP hose O-ring so it's ready for installation. Adapter is designed for 3,442 psi (237 bar) service pressure.

Questions & Answers

Questions about this item:

Shopper  Hello, would this fit onto the hookah port on a vintage DA Aquamaster regulator?
Jeff B  It worked on a late seventy scuba pro mark iv regulator to couple to a current pressure gauge.
Mario C  not sure of the measurements on that double hose reg. This adapter is 3/8" Male to 7/16" Female
Shopper  what is the thread count on each end? I'm looking to have the 7/16 end at 20 and the 3/8 end at 24. If that is so, I will by this part.
BOB H  Yes the 3/8 Male (24 treads per inch) to the 7/16 Female (20 treads per inch) adapter is what your asking for. All the Scuba adapters i've purchased are the fine tread or they will state otherwise.
SEAN K  3/8 x 24 to 7/16 x 20, lets you use old regs with new gauges
PHILIP S  I am sorry, I don't have this gear anymore
DANIEL H  Yes, 7/16-20, 3/8-24.
JOHN M  The answer is Yes, I know for a fact the 3/8 is a 24 count. and I think the think the 7/16 is 20. If you are going to use for a old style ist stage to a newer SPG , buy it.... Jack Murphy ,Florida, Keys . 305-664-8019
ROBERT R  It works just fine i had no leaks
Shopper  Why Did You Choose This?
ERIC C  Purchased a brand new Submersible pressure gauge and need adapter to connect it to my old US Divers Conshelf XIV regulator that I've had for nearly 30 years.
GARRY S  Newer 1st stage regulators have a 3/8" HP hose hole, while low pressure holes are 15/16" so they can not be confused. Old Aqua-Lung regs had a 3/8" high pressure hole, so to attach an old pressure gage HP hose to a newer regulator, it takes this adapter.
Douglas M  I have an older USD regulator with a HP port that is 3/8" & I have HP hoses with a 7/16" thread. Rather than buy new hoses I decided to buy an adapter instead
MR A  Hi name is Bruno Andujar,I am Scuba Diver. I bought this item because the price and quality is good. I will use for my dive school and shop as well.
