Master Paint System MPS Disposable Paint Spray Gun Cup Liners and Lid System, 50 Pack Mini Size 6 Ounce (180ml) Kit - 50 Cup Liners, 50 Lids with Strainer, 1 Hard Cup with Retainer Ring and 20 Plugs

If you take your time and make sure the ring is on right…..no problems at all. Well worth the savings.

I used this cup kit with a Master Pro 44 Series gun and corresponding adapter. I did not have any leakage issues that other reviewers have expressed, despite having my gun at all sorts of angles while painting wheel arches and other hard to reach areas. I have not used the name-brand equivalent but after my good experience with this cup system, I have no reason to switch. The markings on the measuring cup arent as crisp and clear as some other measuring cups Ive used, but they did the job for me. There is no set of 1:1 bars but there is a mL measurement which is suitable for this. One thing worth noting I suppose is that the jaws of the cap are designed to latch onto the cup adapter (which has notches/grooves around it to accept the cap) via a push-and-turn motion, kinda similar to how you would remove the lid on a tamper-resistant medicine jar. I wonder if those who experienced issues with the cup falling off the gun did not realize this, as there are no instructions included with the kit. With the caps jaws engaged on the adapter, youd have to be trying real hard to pull the cup off.. no way it will fall off while in use.

Love this set up for painting, it keeps everything in the cups until you need it and if you want shake it up just before putting it on the gun

as good as 3M half the cost!

good price

Dont BUY!!!!!!!! DOnt BUY!!!!!!! im Furious!!~!!!!

replaced my old style cups diy painter.easy clean up very little thinner for clean up all you have to clean up is the in side of gun.flush it out . first time use no problems worked nice no leaks paint went on better for some reason i almost no over spray with primer gun. and my paint went twice as far build in filter works great.

Good stuff for the money!

I’ve been a body man for 30 years and this set of disposable master paint system worked great for me. I will continue to buy these.

They don’t fit the adapters properly so they leak paint when you turn your gun upside down. I would love to return them but since I used one I can’t.
