The 09446 nylon washer is a direct replacement component for SprayTech Airless EP2300 SE, SprayTech Airless EP2300, SprayTech Airless EP2400, and SprayTech Airless EP2510 sprayers. This precision-molded nylon washer serves multiple functions depending on its installation location. It can act as a bearing surface between moving parts, preventing metal-to-metal contact and reducing wear. It distributes load under bolt heads and nuts, protecting painted or soft surfaces from damage. In some applications, it may serve as a spacer to maintain precise clearances or as a sealing element in low-pressure fluid connections. Nylon material offers excellent chemical resistance to paints and solvents, low friction properties, and will not corrode. A worn, cracked, or missing washer can cause improper clearances, surface damage, or fluid leaks. This replacement washer is manufactured to exact dimensional specifications for proper fit. Installation requires no special tools, but care should be taken to ensure the washer is properly seated. Regular inspection during maintenance helps identify washers that need replacement.
