Strainer Screen and Cylinder m-35 Lightweight Gasket for Mcdonnell F-26

Product Description

The Strainer Screen And Cylinder m-35 is a lightweight replacement gasket designed to fit the McDonnell F-26 low water cutoff assembly. This gasket is a critical sealing component used in boiler systems to maintain a proper pressure-tight connection between the float chamber and the boiler body. HVAC technicians and boiler service professionals rely on precision-fit gaskets like the m-35 to prevent steam or water leaks at critical junction points within the system. A failed or worn gasket at the low water cutoff can allow moisture to escape, leading to pressure loss, inefficient operation, or unsafe boiler conditions. Replacing the gasket with an OEM-compatible part like the m-35 restores the original seal integrity and helps bring the system back to safe operating standards. The McDonnell F-26 is a widely used low water cutoff and pump controller found on steam boilers in commercial and residential heating systems. Keeping this device properly sealed is essential for safe boiler operation, as the low water cutoff is a primary safety control that shuts down the burner when water levels drop below a safe threshold. The m-35 gasket from Strainer Screen And Cylinder Co. is manufactured to match the original dimensions and material specifications of the F-26 assembly. This means technicians can complete the repair quickly without modifying or trimming the part. Whether performing routine maintenance, responding to a boiler service call, or rebuilding a float chamber assembly, having the correct replacement gasket on hand reduces downtime and keeps heating systems running reliably. This part is a standard component in boiler maintenance kits and is commonly stocked by HVAC wholesalers and mechanical contractors.
