This adapter will couple firmly to the 079-00300 (FC-6446) type bleeder screw used in Cleveland brake systems so that you can properly bleed and charge the aircraft's brake lines and cylinder. It has a quick-connect coupler at the other end, which will work with all bleeder tanks (such as the model 225DX Bleeder Tank) or other pressurized fluid systems. It locks firmly in place around the nipple and forms a high pressure seal.
Although I bought this to adapt for use with a vacuum type bleed system, I pressure tested it at much higher pressure than any pressure bleeding system will generate beforehand (120 P.S.I.) It sealed against the bleeder fitting completely without excessive tightening and should work as advertised on any system for a long time.
This product is excellent for bleeding Cub brakes. It is very easy to use and much less messy.
This worked exactly as I expected. The brass fittings are a commercial type which I didnt need for my bleed arrangement. I got the ones I needed from the hardware store and I was able to get the air out of the brake system on my RV7.
Not a real good fit.
Actually 5 stars for design and initial snug fit, but the interior aluminum compression fitting can be easily over-tightened, compressing the nose end to near flat where it will no longer seal. Looking for a sales outlet for the aluminum fitting for way less than re-buying the whole thing.
