You can get all types of bottle with DIN fittings. The thing to note is that the 300 bar DIN female will not accept a 232 bar DIN male. The male is not long enough to bottom. No rude laughter at the back please. This is to prevent a 300 bar bottle supplying air to a hose or appliance not rated to receive 300 bar.
A 300 bar male will work with a 232 bar female.
Wow I've enjoyed this.
