## Questions & Answers

**Q: Does the connectors that come with this product except single or double flare?**
A: I installed this product on a 1968 Pontiac GTO using a double flair. However, you can still use a single flare if thats all you have. Double flares are better becuase it leaves more tubing material at the end for the fittings to clamp when tightened together. A single flare will work fine as long as its a perfect flare. From experience with double flares they dont need to be perfect in order for them not to leak. For example with a double flare; you might have one end .001"-.003'' shorter than the other like a lopsided pyramid and it will probably still seal just fine. But when you do that on a single flare, theres a good chance your fitting will crack or split the end of the single flare thats under the most stress. Like if you do a lopside pyramid on a single flare, its probably gonna leak beacuse it either cracked in the fitting or theres just not enough filler metal to create a tight seal between the fittings. Hope this helps when working on tubing...

**Q: My fittings are metric 10mm, what will I need to make this work?this is s.a.e right?**
A: These have a 1/8-27 NPT but include adapters to go to 3/16-24 Female. You will need an adapter to go from 1/8-27 NPT to 10mm female or an adapter to go from 3/16-24 male to 10mm female.

**Q: What is the flow coefficient of the vale?   (The Cv value.  It's unbelievable this is not in the description.)**
A: Not sure what that means but I believe it reduces flow up to 50% used it on a jeep tj with axle swaps and have had zero issues

**Q: is 8419 disc on disc ?**
A: You would have to elaborate more
