What the K5PTC4 Part Number Means
K identifies a KOPkit and 5 is the head size. In the PTC4 code, P is the glass-filled polypropylene head, T is PTFE seats and O-rings, C is ceramic valve balls and 4 is the 1/4-inch NPT threaded connection.
How to Find the Right KOPkit for Your Pump
The KOPkit number is stamped on the pump nameplate and listed on the specification data sheet. A model in the format XXX5XX-PTC4-XXX takes the K5PTC4 kit.
K5PTC4 Versus K5PTC3
K5PTC3 uses the same Size 5 FPP/PTFE/ceramic materials with 1/2-inch OD tubing instead of 1/4-inch NPT threads. The final digit of the wet-end code identifies the connection.
K5PTC4 Versus K6PTC4
K6PTC4 uses the same PTC4 materials and 1/4-inch NPT connections but fits Size 6 pumps. Head size must match the original pump.
Typical Maintenance Components
Solenoid diaphragm pump KOPkits generally include a pump head, diaphragm, check-valve assemblies and associated service components. Verify the exact contents of the supplied K5PTC4 kit.
Installation and Safety
Disconnect electrical power, isolate the chemical supply and relieve system pressure. Use a compatible thread sealant on NPT connections and follow the official manufacturer installation instructions.
