MFF350 Manual Flange Facer

The CLIMAX MFF350 Manual Flange Facer is designed for precision flange facing operations in both workshop and field applications. Compact, lightweight, and manually operated, this machine ensures gasket sealing reliability and compliance with ASME standards, delivering professional-grade performance without the need for power.

Designed for flat face, raised face flange, and spot facing on carbon, stainless, and exotic alloy steels, the MFF350 covers facing diameters up to 350 mm (13.8″). Its durable construction and three interchangeable ID clamping options provide flexibility for demanding field conditions, while manual operation offers a cost-effective solution with lower maintenance compared to powered machines.
