Bleed Valves & Drain Cocks

Our design-registered bleed valves are precision-milled from solid brass.

Quarter-inch (13mm) and eighth-inch (9mm) BSP threads make Castrads bleed valves suitable for use with a wide range of cast iron radiators. Half-inch (21mm) BSP bleed valves are used with most steel multicolumn radiators.
