This listing is for one brand new high pressure stainless steel bleed valve.  The body has 1/4" NPT male threads.  The knurled knob is 1-1/4" in diameter, and 1/2" thick.  The seat of the valve is made of Delrin.  This valve has a 5000psi working pressure.

This valve would be perfect for use on a SCUBA, paintball, or air rifle high pressure compressed air fill station.  This is a VERY heavy-duty valve.  I am positive you will be impressed with it.
