Part 432-676 is a pressure tube designed for Hydra M and Hydra Pro Super, as well as Hydra M and Hydra Pro 2000/4000 series sprayers. This tube delivers fluid under high pressure from the pump to the spray gun or manifold, ensuring consistent material flow during operation. It restores proper fluid delivery when the original tube becomes worn, cracked, or develops leaks from prolonged use.

The 432-676 Pressure Tube is a critical fluid pathway component designed for Hydra M and Hydra Pro series sprayers. It transports coating material under high pressure from the pump outlet to the spray gun or distribution manifold, enabling consistent delivery and proper spray performance.
Over time, pressure tubes can develop wear from abrasive materials, become brittle from chemical exposure, or develop stress cracks at connection points. A compromised pressure tube can cause pressure drops, erratic spray patterns, or dangerous fluid leaks. Replacing a worn or damaged tube with this new component restores safe and reliable fluid delivery.
| Fluid delivery | Transports coating material from pump to spray gun |
|---|---|
| Pressure containment | Withstands high operating pressures during spraying |
| Flow consistency | Maintains steady material flow for uniform application |
| Visible leaks | Fluid seeping from tube walls or fittings |
|---|---|
| Cracks or bulges | Surface cracks, bulging, or swelling of tube material |
| Brittleness | Tube feels hard and brittle, may crack when flexed |
| Fitting damage | End connections are worn or damaged, causing poor sealing |
This pressure tube (part 432-676) is compatible with the following Hydra sprayer models. Always verify fitment by consulting your equipment's parts diagram.
| Sprayer Series | Component |
|---|---|
| Hydra M and Hydra Pro Super | Pressure Tube |
| Hydra M and Hydra Pro 2000/4000 | Pressure Tube |
When replacing the pressure tube, it's good practice to inspect and consider replacing these related components.
Fittings at tube ends may wear and should be inspected for thread damage or sealing surface wear.
Seals at connection points should be replaced to ensure leak-free assembly.
A clogged filter can increase pressure and stress on the tube; inspect and clean or replace.
