Part number 700-438 is a gasket used to create a leak-proof seal between mating surfaces in compatible sprayer systems. This gasket prevents fluid or air from escaping at component joints. It is compatible with 440 XC Airless_Sprayer; Epic 447ex; and Epic 447HPX models. Replacing a worn or damaged gasket restores proper sealing and prevents leaks.

The 700-438 gasket is a sealing component designed to create a leak-proof barrier between two mating surfaces in compatible sprayer systems. It is specifically engineered for use with 440 XC Airless_Sprayer; Epic 447ex; and Epic 447HPX models. Gaskets are installed between components such as pump housings, valve covers, or motor mounts to compensate for surface imperfections and prevent the escape of fluids or air under pressure. This gasket is typically made from a compressible material such as paper, cork, rubber, or a composite that can conform to surface irregularities and resist degradation from paints and solvents. Over time, gaskets can become brittle, compressed, or damaged due to heat, pressure, and chemical exposure. A failed gasket will allow fluid or air to leak, leading to loss of pressure, contamination, and mess. Symptoms of a faulty gasket include visible leaks at the joint, wetness or staining around the mating surfaces, or a drop in system pressure. Replacing a worn or damaged gasket with this genuine part restores a proper seal and prevents leaks. This simple repair is essential for maintaining the efficiency and reliability of the sprayer. When replacing the gasket, it is important to thoroughly clean both mating surfaces to remove any old gasket material and ensure a smooth, flat sealing surface. Using the correct replacement gasket ensures a proper fit and long-lasting seal.
| Fluid sealing | Prevents paint or solvent leaks at joints |
|---|---|
| Air sealing | Prevents air loss in systems |
| Pressure retention | Helps maintain system pressure |
| Visible leakage | Fluid seeping from between surfaces |
|---|---|
| Hardening or cracking | Gasket material degraded |
| Compression set | Gasket flattened and no longer seals |
| During disassembly | Always replace gasket when separating sealed components |
