Part 944-004 is a replacement PTFE o-ring for a wide range of compatible spray equipment. This precision seal provides excellent chemical resistance and low friction, preventing fluid leaks between mating components. When the original o-ring becomes cut, flattened, or brittle, replacement restores leak-free operation.

The 944-004 PTFE o-ring is a direct replacement sealing component for a wide range of spray equipment including numerous PowrTwin models (12000GHD, 12000GH, 12000 GHD, 8900GH, 6900GH, 4900GH, 4500, 3500, 3500 50th anniversary), various PowrLiner models (8900, 6000, 5000, 4900, 4000), Hydra M and Hydra Pro 2000_4000, Hydr M nad Hydra Pro Super, Commander, and Admiral equipment. This o-ring is made from PTFE, a material known for its exceptional chemical resistance, low friction, and wide temperature range capability. PTFE o-rings are used in applications where standard elastomeric o-rings would degrade due to exposure to harsh paints, solvents, or hydraulic fluids. They provide a reliable seal in high-pressure and chemically aggressive environments. A properly functioning PTFE o-ring ensures that fluid flows correctly without leaks or pressure loss. A damaged or worn o-ring can cause fluid leaks, pressure loss, and system contamination. Symptoms include drips from fittings, loss of prime, erratic operation, or visible fluid seepage. This replacement o-ring is manufactured to exact dimensional specifications for proper fit. Installation requires careful cleaning of the sealing surfaces. Regular inspection during maintenance helps identify o-rings that need replacement.
| Fluid sealing | Prevents leaks between components |
|---|---|
| Chemical resistance | PTFE resists paints, solvents, and fluids |
| Low friction | Reduces wear on mating surfaces |
| Visible cuts / nicks | Damage allows fluid bypass |
|---|---|
| Flattened / deformed | O-ring no longer provides adequate sealing |
| Hardened / brittle | Material has lost elasticity |
| Fluid leakage | Visible leak at sealed joint |
