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

They work pretty well as they should. The tops have a really good strainer. Very tight fit with a nervous crunch when you twist onto the 3M adapter. On siphon applications the seal easily blows out during cleanup if spray is even slightly restricted with your hand or towel. You cannot interchange with similar 3M products. The ID of the liners is .035 smaller than 3M. I use a 3M pressure cup with Apollo HVLP system. They fit the cup very loosely and are a challenge to fit in the cup and seal. Especially when fully loaded. If you use only gravity/siphon feed you should be OK.

Better to buy these and have them around for small amounts of paint then to waste the bigger ones

Tried using this junk 3 times 1 time it worked without leaks 2 times leaked dripped everywhere. The cap sealing to permanent cup seems to be an issue as with other users. All three uses resulted in the cap breaking off inside the adapter that you BTW must purchase elsewhere for 25 bucks. Going back to old way this is a waste of time and money.

Ive been using 3M PPS cup system since 2014 with my Fuji Q4 turbine/XPS and T series spray guns as well as multiple compressor HVLP spray guns with adapters. These Master Paint versions of cups/liners and lids work just the same. No leaks ever on this system nor the PPS system. These provide considerable savings to the PPS ones which is great. I generally reuse liners and lids as least once extra time when doing water based products because its just easy to clean them out with hot water. I dispose of the liners and lids when I spray solvent materials though after I get multiple spray sessions of the same product over 1-2 days. I would not hesitate to continue buying these for the savings over the branded PPS products. I find the 6oz and 20oz cup sizes to be the most practical. Going larger to the 28oz size puts a lot of weight for gravity feed guns and can slow down maneuvering on anything but flats objects.

They are very nice product. They arent the top quality as 3M, but for the price and as many as I use....awesome and very happy. I plan to keep buying them.

These work just as well as the 3m version but a fraction of the price

Great value!

Good for the money

leaks

Works as good as the 3M cups
