Brake line fittings

[Moparigno]

Hello,

I'm plumbing my brake lines and I need to get some good quality hardline fitting. I get the BrakeQuip catalog. It seems good quality stuff.

I see two different "seat types" for tube joiners: seat "X" and seat "Y".

I guess they refer to the type of flare you gonna use.

Do you know what seat type fits SAE 45 degree double flare ?

In the image you posted, "X" is a 45 degree inverted flare and "Y" is a 45 degree bubble flare. Either is an effective option, however the inverted flare has been the standard for most muscle cars since their inception since that's what they came with from the factory.

thanks for the answer. I have a late model GM master cylinder (C6 Corvette). It should have (2x) M12x1.0 SAE metric inlets. Do you know if they require bubble flares as most of EU cars ?

The C6 Corvette MC actually has M12x1 metric inverted flare outlet ports, not bubble flares. FWIW, the C5 Corvette MC's were bubble flares, but only the '97 was (2x) M12x1, whereas the 98-04 were (1x) M12x1 and (1x) M12x1.5, the latter of which can be difficult to source suitable tube nuts.

Since you said you have the C6 master cylinder, a quick look inside the ports will confirm what they are
