Pressure regulators help keep critical systems operating at the correct pressure—fuel delivery, common rail pressure control, injection control pressure, and pneumatic/air compressor regulation. The right regulator supports stable performance, easier starting, and consistent system response across off-road machinery and industrial applications.
If you’re shopping for air-system components more broadly, browse our Pneumatic Parts category for related valves, fittings, and air-control parts.
| Type | Regulates | Application |
| Common Rail Pressure Regulator (DRV) | Rail fuel pressure (high pressure) | Common rail diesel systems |
| Injection Pressure Regulator (IPR) | Injection control pressure | HEUI-style diesel systems |
| Fuel Pressure Regulator (Low-Pressure) | Feed/return fuel pressure | Fuel rail / low-pressure fuel circuits |
| Air Compressor Pressure Regulator / Unloader | Compressor load/unload pressure | Rotary screw compressors |
Need help identifying the right regulator? Send FridayParts your serial number, engine/compressor model, and a couple of clear photos of the old part and connectors/ports. We’ll help you verify the match—then you can place your order quickly and get your equipment back to work.
