AirCraft Fluid Cap Washer For AB17G (SG AB17G-15)
At a Glance: Replacement fluid cap washer for the AB17G—supports proper sealing to reduce leaks and keep spray performance consistent.
A spray gun’s finish quality depends on stable pressure and proper sealing—especially around the front-end assemblies. The AirCraft SG AB17G-15 Fluid Cap Washer is a replacement sealing washer designed for the AB17G spray gun, helping the fluid cap seat correctly and maintain a tight seal. If the washer is worn, flattened or damaged, you can end up with seepage, air leaks, inconsistent atomisation or messy buildup around the cap. Replacing this washer is a simple, low-cost service step that helps keep your AB17G clean, leak-free and spraying evenly.
Fluid cap washers compress to fill tiny gaps between parts and support correct alignment and sealing. Over time they can deform or harden, leading to leaks and spray inconsistencies. A fresh washer helps restore proper seating and stable performance.
