## Questions & Answers

**Q: will this fit a 1997 honda accord?**
A: maybe i'm too late to answer, but if your honda has 3/16 in lines, these will fit. these are to be used as a unit, 2 nuts and a union to connect two lines together. I don't believe these nuts will fit in any other components on your vehicle.

**Q: will these work with stainless steel brake line?**
A: No, stainless steel requires 37° single flare with collars and flare nuts

**Q: are these compatable with caliper  Jaguar 1991 3/16 inverted flare**
A: These are double flare fittings. As long as you double flare the tubing end it should work on any 3/16 inch tubing. Do not have any info concerning a Jaguar

**Q: These are not for bubble flares, correct?**
A: They will work on ¨double¨ flare fittings. Not familiar with bubble flares.
