Description
Xylem-McDonnell & Miller 323400 Head Gasket — Package of 10
Keep your McDonnell & Miller 94 and 194 Series low-water cutoff and pump controls operating reliably with the OEM-specified head gasket replacement kit. The 323400 package includes ten (10) Model 92-68 head gaskets, giving service technicians and boiler room professionals a ready supply of genuine replacement seals for scheduled maintenance and emergency repairs alike.
Product Overview
The head gasket provides a critical pressure-tight seal between the control head and the float chamber body on McDonnell & Miller 94 and 194 Series combination low-water cutoff/pump controllers. A compromised or aged gasket can lead to steam or water leaks at the control body joint, resulting in unsafe boiler operation and costly downtime. Replacing the head gasket during routine annual maintenance or at any sign of weeping is a best practice recommended by the manufacturer.
