The valve is an oxygen shut off valve that a paediatric regulator fits on. I can steal one off a medical oxygen tank but I built the sub to take a valve with 1\4 pipe male fitting. I can't find one because I don't know what it is called?</div><div id="yui_3_16_0_ym19_1_1484087934751_2855" dir="ltr">Hank</div></div></body></html>
