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

The only real flaw with these adapters is that the threadwell is shallow and it is prone to leaking. If you add an O-ring into the adapter, it will seal better, but then the adapter will spin when you mount and dismount the paint cups. Its good, just not great. Could be great if they machined the thread well a little deeper and added an O-Ring.

If you like the original 3M pps, then you should like these. I use on a regular basis for primers, base,single stage and clears. They work well for me. No leaks or issues. Good value if you dont want to use a hard cup.

Bought these on a whim, no regrets. Dont know what other people are saying that these are not good, they are decent liners, caps, and cup. Yes the liners are thinner and slightly smaller lips they seal and work great for solvent and water based material. Been using 3M PPS in our shop for 10+ years, wish I would have found these years ago.

Good sizes for a good price.

Product arrived on time and was to my satisfaction

leaks

These things are garbage. They’re plastic.

This product will make our painting process much more efficient. I was using way to much cleaner for what little I was painting

I ordered this the first time and I never got it. Had to get a refund and reorder it. Other than that this is a great replacement part. My original spray gun had a plastic piece and it stripped after the first use when I was taking the cup off. This is nice and sturdy. Works well. Price I feel is a little bit higher than I wanted but it was worth the money.

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
