Does the job and saves money in the long run.

Works perfectly. Heavy duty and firefighter proof


No problems

By Shane C.

Fits the SCBA compressor at my fire station perfect. Don’t think there’s a difference in threads for SCBA’s but if there is ours are 4500 psi Scott packs

If you're a firefighter you have worked with CGA Valves on SCBA's. This SCBA to Scuba Adapter allows filling off fire department compressor equipped with a CGA 346 filler whip to fill scuba tanks up to 3200 psi (220 bars) using this adapter.

SCUBA fill adapter

By Cameron B.

The scuba fill adapter worked flawlessly. Makes filling SCUBA from a SCBA fill station seamless!


Just as advertised.


from Ocqueoc, MI, US

It does exactly what it's supposed to.


Great Fire Department fill

By Matt T.

Great for filling from an SCBA compressor!


Yes I would buy this product again

By Donny

Great service and fast delivery thanks Leisure Pro.


Works great +++

By chuck

I used this adapter in a SCBA fill machine and it worked great. Filled my SCUBA tank up to 2900 PSI with on problems.


Works like a charm

By Taggart

Well built unit, works perfectly! No leaks. Pays for itself in about 9 fills.


Simple solution all teams should have

By zerovizdiving

Dive teams can get caught on a site for extended periods, as we have. Having this adapter (now the second one I own) provides for the ability for the local fire department we may be assisting to be able to fill our tanks. We have been up to 7 days on a search and having the ability to fill without traveling to the nearest scuba cascade(over an hour away that time) allowed us to continue our task without sacraficing a runner to go get fills. I would like to see the dust caps come with this item and, although, not listed with item and was not expecting to get caps, sure keeps the dust bunnies out when not in use.


Built heavy duty for years of service.

By Blackwater507

My online purchase was fast and easy and the adapter arrived quickly, and was well packaged. Thanks Leisure Pro for a job well done.


Big money saver

By Don

This product is not for the novice, but it will save you money and pay for itself. I have access to a properly maintained compressor system that is rated Grade E (air grade quality for diving). I am the person responsible for this system so I know I can trust the air quality. If this applies to you as well and you dive often, it will pay for it self in a couple of dives with your buddies.


Great product

By Matt

Work's as good as they said it would.


Small but functional

By L.G

Easy to use. I am a firefighter and use the adapter to fill scuba cylinders from an scba fill station.


SCBA adapter


Fit my tank and worked as promised. We refill air rifles from these scuba tanks and we needed an adapter to work with the local fire company fill station. Filled two tanks without any problems using the adapter.


SCBA Adapter Needed? Buy this one!!

By Boy S.

There was no Dive Shop anywhere near the lake I was planning on Diving (nearest shop was 50 miles away abd I wasn't about to rent 6 tanks for my multi dive plans. I rented two instead and and had them filled locally at he Fire Dept. Just a simple phone call to the local Dept before my trip to confirm I would be able to BUY air fills to support the local Fire Hall and voila!!! Problems solved, with the adapter i was able to get air fills just a few miles awy from the lake. Thanks Leisure Pro!!!


Questions & Answers

Questions about this item:

Shopper  Why Did You Choose This?
Michael S  Thank You
John M  Just received this and can't use it. Our compressor is used to fill our Scott bottles to 5500 psi. Do you think a CGA 347 adapter will be my fix?
ROBERT G  I use my adapter to fill my bottles from my FD's compressor without any problems. I adjust the compressor's psi output to 3000 down from 5500.
John M  I had to remove the CGA 346 and screw the fill whip directly into the unit to make it work. I have a CGA 347 coming to me.
HERBERT B  We ordered the 347 adapter for our compressor at the Fire Dept. and it works fine
John M  Thank you.
JOHN O  Yes it is a CGA fitting. Check online with breathing air systems, they should have the fitting or if you have spare scott packs that are out of service you can take the fitting off of it.
B B  Just curious -- why can't you use it? I use mine (model shown) to fill my scuba tanks using our compressor system with no problems. We have a Mako compressor system and Scott bottles and the threads fit on the fill output (female collar) side with no issue. The only thing I need to do is make sure the safety catch lever on the inside is pushed up (I use a structural glove) since I can't close the door with the aluminum 80s I'm filling. Mako technical support is who told me to do it that way -- and ensure I don't overfill by setting the pressure relief regulator to 3300 before I fill.
John M  The CGA 346 fitting has a safety bleeder hole drilled into it. I guess to prevent you from using anything rated for above 3000 psi. I don't believe the CGA 347 has that drilled safety hole.
Shopper  Does anyone know the thread size on the brass adapter?
KEVIN F  Thread size is 0.830”-14 NGO right handed Best matched with CGA 346
