Part number 0089482 is a nylon sealing washer designed to create a leak‑tight seal between fluid connections in airless sprayers and related equipment. It prevents fluid leakage at threaded fittings, swivels, or pump connections, helping maintain consistent pressure and avoiding messy drips. This genuine nylon washer is a direct replacement for the original component on compatible ProFinish, CapSpray, and SprayTech units.

The 0089482 Nylon Sealing Washer is a precision‑molded component used to seal fluid connections in airless and air‑assisted sprayers. It is commonly found at pump outlet fittings, swivel joints, hose connections, and filter housings. The washer compresses slightly when the fitting is tightened, filling microscopic gaps and preventing fluid leaks under high operating pressures.
Over time, nylon washers can become brittle, crack, or take a permanent set, leading to seepage, pressure loss, or air ingestion. Replacing a worn or damaged washer with a new 0089482 restores a reliable seal and ensures the sprayer operates at peak efficiency without drips or performance issues.
| Leak prevention | Creates a positive seal between metal fittings, stopping fluid escape |
|---|---|
| Pressure maintenance | Helps the system hold consistent pressure for uniform spray patterns |
| Contamination barrier | Prevents air from being drawn into the fluid stream, reducing spitting and uneven spray |
| Visible leakage | Fluid seeps from the connection even after tightening |
|---|---|
| Hardening / cracking | Washer feels brittle, shows cracks, or breaks during disassembly |
| Compression set | Washer is permanently flattened and no longer springs back |
| After fitting removal | Always replace the washer when you disconnect a fitting that uses one |

When replacing a sealing washer, it’s good practice to inspect these related components, as they often wear out or become damaged at the same time.
Adjacent O‑rings in pump or filter assemblies may also be compressed or aged; replace them to avoid future leaks.
A clogged filter can increase back pressure and stress seals. Clean or replace the filter when servicing washers.
If the fitting itself is worn or damaged, consider a complete repair kit that includes new washers and seals.
