Why Viton Seals Matter

The Viton sealing specification distinguishes K4VVC1 from kits using PTFE or Hypalon. Confirm the chemical resistance of the original sealing material before selecting replacement components.

PVC Head and Ceramic Check Valves

The PVC head and ceramic valve-ball configuration should match the original pump liquid end. The catalog describes a ceramic ball rather than a PTFE double-ball arrangement.

Preventive Maintenance Application

A KOPkit provides common service parts for maintaining the pump liquid end. Keeping a compatible kit available can help reduce downtime when replacement becomes necessary.

Size 4 Versus Size 2

K4VVC1 is a Size 4 kit. K2VVC1 uses the same abbreviated PVC/Viton/ceramic material designation but belongs to the Size 2 family. Head size is an essential part of replacement selection.

Connection Verification

The tubing designation is 3/8-inch outside diameter. Check the original fittings and complete VVC1 wet-end code before ordering.

Maintenance and Installation

Follow the manufacturer service schedule. Disconnect power, isolate the chemical supply and relieve system pressure before replacing liquid-end components.
