The InoKraft disposable paint sprayer gun cup system streamlines your entire painting workflow with just 5 parts. This complete kit includes 1 reusable hard cup, 1 retainer ring, 45 disposable cup liners, 45 filter lids and 20 sealing plugs, providing an all-in-one solution for measuring, mixing, filtering and spraying paint materials. Mix paint directly in the liner using the built-in measurement lines, then snap on the filter lid and spray. When you are done, simply swap the liner for a fresh one, so there is zero cleanup between colors or coats. Seal unused paint with a cup plug for future use, saving on paint waste and solvent costs over time. The precision-molded lid and liner create an airtight seal that lets you spray at any angle, even upside down, without leaks. Built-in 125-micron filters deliver a finer, more even coat than standard 190-micron filters, and the system works with all paints, primers, epoxies and commercial coatings. Compatible with HVLP and LVLP spray guns through adapters (adapters sold separately). Ideal for automotive, marine, woodworking and professional painting projects. Material: Plastic.
