Product Description

Genuine Water Seal Repair Kit for Interpump High-Pressure Pumps – Kit 242

The genuine factory Interpump KIT 242 repair kit is engineered for the complete overhaul and servicing of high- and low-pressure water seal assemblies in Interpump and General Pump triplex plunger pumps. Manufactured in Italy, this complete seal kit contains original elastomeric high-pressure seals, low-pressure seals, O-rings, and support rings designed to fit precisely into the pump head manifolds. Replacing worn seals with original Interpump components restores nominal operating pressure, prevents fluid leakage, and eliminates damaging head pulsations.

Key Features & Operational Benefits of the Interpump KIT 242:

• 100% Original Interpump Group Part: Manufactured in Italy using premium elastomeric rubber compounds that offer exceptional wear resistance and thermal stability.

• Stabilizes System Pressure: Regular maintenance with genuine seal kits prevents line pressure drops and erratic hose pulsation during wash cycles.
• Protects Wash Bay Equipment: Properly sealed pump heads prevent water from leaking back into the crankcase oil. Learn more in our comparison article CAT vs HAWK pump ranking guide and our winter car wash preparation guide.
