This adapter will couple firmly to the 079-00300 (FC-6446) type bleeder screw used

in Cleveland and Matco brake systems so that you can properly bleed and charge the

aircraft’s brake lines and cylinder. The other end connects to any hose having a 1/4

NPT male thread. It will work with all bleeder tanks (such as our model 225 Economy

Bleeder Tank) or other pressurized fluid systems. It locks firmly in place around the

nipple and forms a high pressure seal, so there is absolutely no chance of leaking fluid.
