TITAN 50504 O-RING-OEM
SprayTech part 50504 is an o‑ring designed to provide a leak‑tight seal in the fluid section or manifold of compatible SprayTech Airless sprayers. This o‑ring prevents fluid bypass, maintains proper pressure, and ensures consistent spray performance. Replacing a worn, flattened, or damaged o‑ring restores sealing integrity, eliminates leaks, and helps maintain optimum pump efficiency.

The SprayTech 50504 O‑Ring is a critical sealing component used in the fluid section or manifold of compatible SprayTech Airless sprayers. It creates a positive seal between mating surfaces, preventing fluid bypass and maintaining consistent operating pressure. A properly functioning o‑ring ensures reliable spray performance and minimizes waste due to internal or external leaks.
Over time, exposure to harsh coatings, solvents, and normal wear can cause the o‑ring to become flattened, hardened, or cracked. A compromised seal leads to pressure loss, erratic spray patterns, or fluid leaking from the pump area. Replacing the o‑ring restores sealing integrity and allows the sprayer to operate at its rated pressure and flow.
| Seals components | Prevents fluid bypass between mating parts |
|---|---|
| Maintains pressure | Helps the pump build and hold operating pressure |
| Prevents leaks | Eliminates external weeping from sealed joints |
| Pressure loss | Pump struggles to reach stall pressure or pressure drops under load |
|---|---|
| Fluid leakage | Visible seepage around the sealed joint or manifold |
| Worn / flattened | O‑ring shows signs of compression set, cracks, or hardness |
| During rebuild | Always replace when servicing the component it seals |
SprayTech part 50504 is compatible with the following SprayTech Airless sprayer models. Always confirm fitment using the correct parts diagram for your exact model and serial number.

When replacing the o‑ring, it is good practice to inspect and often replace these associated components to ensure a complete and reliable repair.
If the fluid section is being serviced, replace all packings and seals.
Check the mating surfaces for damage or debris that could affect sealing.
If the pump is experiencing pressure issues, inspect the valve assemblies.
