11 rental Tippmann C98 all have 20 oz Smart Parts on/off valves.
Saves O rings and CO2. Different colours.
Don't have any weaknesses with this product.
Great to save your CO2. Looks good doing it. Smart Parts kicks but. For those of you who complain about CO2 left in your marker, it's really not the valve's fault at all, your marker holds CO2 in the lines and stuff so don't blame the valve. The valve does have a bit of grease on the stem so those of you who have a hard time turning it maybe need to apply some grease next time your tank is empty take the valve apart with the snap ring and grease it. Also your valve stem may be bent or someone cranked on the body of the valve too hard and buggered the body of the valve. BUY THIS PRODUCT!!
BUY IT. USE COMMON SENSE WHOEVER INSTALLS IT AND ALL MOVING PARTS NEED TLC! I have 11 markers with this set up (rental units of course) and have never had a problem with these valves.
