Pop-off valve replacement

Basic replacement pop-off valve that fits 95% of all veterinary and human anesthesia machines.

NOTE: Will not fit Matrx brand machines with the Matrx factory occlusion valve. Will fit Matrx machine without factory occlusion valve but the threads are slightly different and when you screw in the pop-off valve it will "cut" new threads into the clear plastic exhalation dome cover (does not leak). 

• Standard 3/4" thread pattern.
• Standard 19mm outlet port.
