Universal fit: internal 1/8' thread interface with an external connection compatible with standard airbrush fittings, so it screws directly onto most airbrush setups. Keeps airbrushes dry and clean: an efficient separator that removes moisture and small impurities from compressed air to reduce sputtering, clogging, and finish defects. Simple, reliable operation: screwon installation with a builtin metal filter core (brass/copper) that separates water and oil from the air stream for consistent spray performance. Durable construction: polypropylene (PP) body paired with a metal filter core provides long service life and reliable performance under regular use. Compact and maintenancefriendly: small footprint that fits into tight air tool setups and is easy to inspect and when needed. Practical applications Hobby model painting: prevents water and oil contamination from affecting fine detail work and paint adhesion. Automotive touchup and small parts: improves spray consistency for small panels and trim work. Beauty and craft airbrushing: reduces interruptions and touchups in nail art, makeup, or custom craft projects. What you get A screwon water separator filter with internal 1/8' thread, external connection for airbrushes, a metal (brass/copper) filter core, and a PP body designed to protect and extend the life of your airbrush tool.
