Comparing The two Different Valve Stems For the Midmark M7 Autoclave Fill/Vent Valves

Some fill/vent valves on the Midmark M7 Autoclaves were replaced with the RPI valve. To make sure You are ordering the correct repair kit, you need to determine which valve you have. Simply follow the directions below to remove the valve stem and look at the size of the 2 o-rings as shown in the picture to the right

If the o-rings are the same size, then this is the kit you need. If one is smaller than the other, then you need to order the RCS098-842

You can also measure the diameter of the stem, just below the screw head. If it measures ~1/4 inch, then this is the kit you need. But, if it measures ~1/8 inch, then you need to order the RCS098-842

SERVICE TIP: AllClaveParts offers a less expensive alternative to replacement of the Fill-Vent Valve with this kit. Now you simply replace the valve shaft and o-rings, instead of replacing the entire valve
