• Hand tightens into Scuba tanks with a 300DIN or 200DIN opening with No Wrenches!
• Heavy duty bleed valve
• 15″ air line ends with a Female Quick Connect
• easy to read 5000 psi oil filled pressure gauge.

Note: A 300DIN will work in a 200DIN situation but not vice versa (the threads are the same- a 200DIN has less threads).
