What the K7PTC3 Part Number Means
K identifies a KOPkit and 7 is the head size. In the PTC3 code, P is the glass-filled polypropylene head, T is PTFE seats and O-rings, C is ceramic check-valve balls and 3 is the 1/2-inch OD tubing 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. From the model number, the fourth character is the head size and characters seven through ten are the wet-end code. A model in the format XXX7XX-PTC3-XXX takes the K7PTC3 kit.
K7PTC3 Versus K6PTC3
K6PTC3 uses the same PTC3 materials and tubing but fits Size 6 pumps. Head size must match the original pump.
K7PTC3 Versus K7WHC3
K7WHC3 also fits Size 7 heads with 1/2-inch OD tubing, but uses a high-pressure PVC head and Hypalon seats and O-rings. Match the complete wet-end code before ordering.
