I'm looking for a fitting to join a 3/16" brake line to a 1/4" brake line. Any ideas? thanks

Even Home Depot might have what you need in brass. You're looking for a flare to flare reducing union.

Wouldn't use a fitting from Home Depot, they are not certified for automotive use, especially brake use.

Yeah, I thought about that after I posted it. Should probably be steel.

H/D would be fine, alot of gas line fitting are sold their and that could blow up your house or neighborhood and people still buy em and I'm sure they haven't caused anyone's house to blow up yet. Its a piece of brass , Not like it has any moving parts.

Natural gas lines and fittings do not see anywhere near the pressures hydralic brake systems operate at. Goofy analogy if you ask me.

I checked through various product lines and even competitors, and was not able to find a fitting that would do this in one step.

The best I could find was a 1/4" (7/16-24) inverted tube union, and then a "step-up" adapter from 3/16 (3/8-24) to 1/4 (7/16-24).

(Pics courtesy of American Grease Stick -- yes they sell brake line and fittings.)

If someone has seen something different, I'd sure like to be made aware of it.

If it doesn't leak after its installed, its not just gonna spring a leak because you bought it at lowes or HD. if it works at the start it will continue to work after, Unless the so called inferior brass,( that is made by the same overseas company that make the same fitting for NAPA ) suddenly shapeshifts and springs a leak, In either case its not gonna just fall off going down the road. Geeze its no wonder this country is on the skids, Its full of sissies.

Hey Jim, bunch of sissies, I like it! Wasn't sure about the compatability of brass and steel. Not up on my metalurgy. If it's OK then HD has

I've thought of a more elegant solution.

Ford, for sure, used a steel brake line nut that was for 3/16 tubing ... yet had an "oversize" 7/16-24 thread size, which is the exact same size as the "standard" 1/4" tube nut.

Cut off the original 3/16 tube nut and replace it with this "oversize" one. Now both nuts should thread directly into that inverted flare coupler.


(This picture may appear to be brass, but the description says "steel")

HTH,
Don

PS.

A steel tube nut and a brass inverted-flare union is (to my knowledge) perfectly OK. No galvanic corrosion issues. Think about it ... tranny cooler fittings on an automatic transmission were brass (as they also were at the radiator) ... and they used 5/16" steel line. Fuel pumps also had brass fittings and steel lines.

I have also been told that the correct way to splice brake lines is to use double-flared lines and an inverted-flare union.
1000% better than a compression fitting!!!

(Yup, I have had customers tell me that they have made repairs to steel brake lines using compression fittings!)
