Description The -8 ORB to M10 x 1.25 Bleed Bolt Adapter was originally made to convert the -8 ORB port on the H22 Thermostat Housing Delete to a Bleed port, but seeing as how M10 x 1.25 is so close to 1/8″ NPT that you can effectively drill through this adapter, start a 1/8″ NPT tap very easily, and turn it into a -8 ORB to 1/8″ NPT adapter. NOTE: The bleed bolt is not included. I recommend a thread sealant if you choose to tap this part, being there will now be multiple threads in the part.
