Airless Spray Gun Nozzle Set 515 – Superior Precision and Durability for Professional Painting
Looking for a reliable solution to achieve perfectly smooth surfaces without the hassle of cleaning and constant clogging? The 515 Airless Spray Gun Nozzle Set (SKU: M80635-6) is an indispensable accessory for any painter, DIYer or professional using airless spray systems. This high-quality nozzle, made of durable tungsten steel, ensures superior paint atomization, even application and an exceptionally long service life.
Thanks to its clever design, it allows you to work quickly with minimal mist, which means less paint consumption and a cleaner working environment. Whether you are applying latex paints, dispersions or varnishing wood and metal surfaces, this nozzle will ensure professional results without visible transitions.

Why choose the 515 airless gun nozzle set?
When painting with airless technology, choosing the right nozzle is crucial to the final appearance of the surface. The 515 nozzle is the optimal choice for medium to large projects. The first number "5" indicates the spray angle (50 degrees), which creates a wide and even beam, while the last two numbers "15" indicate the orifice size (0.015 inches), which provides the ideal flow for medium-density materials.
The main advantage of this set is its exceptional wear resistance. Since the nozzle core is made of hardened tungsten steel, the orifice will not expand quickly, meaning your spray pattern will remain precise even after hundreds of liters of paint have been used.
