Air Venturi Female DIN 300 Adapter, Female Quick-Disconnect

I travel to avoid the winter in OH. Wanted a means refill my Steyr while traveling. A hand pump at my Son's allowed me to fill and practice with the Steyr. It does work but a bit difficult. You must unscrew the cylinder while connected to the pump to avoid draining it down. If you try to crack the drain the pump it drains the cylinder as well. Not a big deal if you understand how it works. No check valve between the pump and cylinder.

Make it cheaper. Or offer a different more expensive version with a built in check valve.

Pyramyd Air always has what you need and usually at the best price

This is very well made. If you have a tank with foster fittings that you need to get filled at a scuba shop, this is for you. This adapter goes from female din to female foster. Female din is what scuba tanks have, so scuba shops have the adapter to plug into it. Foster is what my pcp tank kit came with.

If you have a scuba tank, and you want to fill your pcp gun with it. You would need the male din version of this adapter. Scuba tanks have either a female din or yoke connection.

Heavy duty, well made fits well.
