Hoses & Fittings

If your arm has lost suction at the hood but the fan is still running, check the hose for collapse and the joints for leaks before you look at the collector. You have hose, tube, slip collars, and connection hardware here for Parker arms and portable units, with part numbers in the title. Diameter matters more than length when you are matching a collar or a connector, because 6 in. and 8 in. fittings will not adapt to each other without a reducer.
