General Pump Kit 04 (K04) is the genuine OEM valve cap and O-ring kit for General Pump CW47 and T series pumps. The brass valve caps hold the inlet and outlet valve assemblies in the manifold, and fresh caps with new O-rings restore a leak-free seal when the originals corrode or weep.
- Genuine General Pump OEM brass valve caps with O-rings
- Coarse-thread version (a fine-thread K04F is offered separately)
- Fits CW47 and all T series pumps
Replace valve caps and O-rings during a valve service to eliminate manifold leaks.
