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

Buy this regularly. Great value. Disappointed at the delivery day switch. Bought due to Prime delivery for a Monday along with a few other prime next day deliveries. 3 over the 4 were delayed and took 3 -5 days to get. Luckily things did not go as planned but this type of action could have been problematic.

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.

It makes work easier. Change of color? Put paint back, clean gun and get a new cup. Time saver.

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.

Just about an exact match to 3ms 6 oz version. Only it’s fit into the adapter isn’t as snug as I’d like . Had some leaking issues

Lids are not sturdy enough consistently. We have had to throw out 4 or 5 in the first batch so far because the lids are not holding up when we attach them to the spray gun.

Very good item

Good stuff for the money!

Easy to fit and use. comes apart for easy cleaning when using gelcoat. a must buy saves resources

Makes cleanup so much easier and the cup last a long time
