General Pump Kit 158 (K158) is the genuine OEM nickel-plated valve cap and O-ring kit for General Pump HTX (Emperor) series pumps. The valve caps retain the inlet and outlet valves in the manifold, and fresh nickel caps with new O-rings restore a leak-free seal on these hot-water Emperor pumps.

- Fits HTX (Emperor) series pumps (HTX1810S, HTX1812S, HTX1813S)
