HIGH VACUUM PUMP SHUTOFF AND VACUUM RELEASE BALL VALVE​​

Our three-way brass ball valve with T-full port and 3ea. 3/8" Hosebarb connections will hold a vacuum in your system, isolate the vacuum pump to prevent oil backup, and release/bleed air back into your system all in one.  An external vacuum gauge can be connected to the third valve to take a system vacuum reading isolated from the vacuum pump.
