Raymond Hose Clamp 1.25 to 2.25 Inch – RA811-921

Sized to clamp hose from 1-1/4 to 2-1/4 inches in diameter, this Raymond worm-drive hose clamp tightens a steel band around a hose to hold it onto its fitting and seal the connection against leaks. Turning the worm screw draws the band down evenly around the hose, applying the clamping force that keeps a pressurized or gravity-fed line from slipping off or weeping at the joint.

The band and housing are steel, which gives the clamp the strength to hold clamping tension over time and through the temperature and vibration cycles of a working machine. The 1-1/4 to 2-1/4 inch range covers a common band of hose sizes, so a single clamp fits a spread of coolant, fuel, hydraulic return, and general-purpose hose diameters rather than one exact size. Match the clamp range to the outside diameter of the hose it will hold, since a clamp holds best when the hose diameter falls within the band's working span.
