Product Description

Genuine Unloader Valve Repair Kit for Interpump High-Pressure Pumps – Kit 241

The genuine factory Interpump KIT 241 repair kit is engineered for the complete overhaul and servicing of brass unloader/bypass regulation valves and pressure seal assemblies in Interpump and General Pump triplex plunger pumps. The set includes original precision components — featuring the brass piston guide body, stem, high-pressure elastomeric seals, O-rings, and support rings. Servicing your pressure regulation valve with genuine Interpump parts restores smooth pressure control, eliminates internal bypass leakage, and protects your high-pressure pump system against destructive pressure spikes. Looking for other pump replacement parts or complete pump units? Explore our full catalog in the high-pressure pumps section as well as our broader range of car wash spare parts.

Key Features & Operational Benefits of the Interpump KIT 241:

  • 100% Original Interpump Group Part: Manufactured in Italy with high-grade brass components and abrasion-resistant elastomeric seals for exact dimensional fitting.
  • Complete Bypass Valve Overhaul: Restores essential valve internal components responsible for smooth idle switching and consistent operating line pressure.
  • Cost-Effective Maintenance: Rebuilding the valve core with genuine internal components saves you from buying an entire replacement valve housing while preventing downtime.
  • Protects Wash Bay Pumps: A properly functioning unloader valve safeguards pump manifolds and pressure lines against hydraulic overpressure. Learn more in our comparison article CAT vs HAWK pump ranking guide and our winter car wash preparation guide.
