## Questions & Answers

**Q: do you keep the same torque specs?**
A: Recommended Torque Settings:
1/4" - 13-17 Ft-lbs
3/8" - 24-31 Ft-lbs
1/2" - 36-45 Ft-lbs
5/8" - 45-60 Ft-lbs
3/4" - 66-88 Ft-lbs

**Q: Whats the max temp and psi for these?**
A: Rated with a -40°F
to 300°F temperature range and corresponding refrigerant
pressures in today’s refrigerant systems.

**Q: can these be reused after they have been torqued? Is this technically a crush washer?**
A: We have customer that do re-use these seals.    FlareSeal act as a crush seal with several points of connection along the flare surface.  However, I would recommend going with a new seal for the best long term connection.

**Q: Will these work for r32**
A: I think you are asking "will they work for R132 freon" and yes they will if you are using a flair connection to your AC unit.   R132 does not run nearly as high pressure as 410 so just a well made flair is probably all you will need.   I've used these but have mixed feelings about them. Sometimes they work great.  But for a zillion years, the flair connection worked perfectly without them, IF it was made well with a good flair tool.  You might also look at this product as an alternative.  A few drops on your flair connection and you gain a lot of insurance against leaks for any type of AC gas.   https://www.amazon.com/Refrigeration-Technologies-Sealant-RT201BP-RT200RP/dp/B0BYX4DYVL/ref=asc_df_B0BYX4DYVL/?tag=hyprod-20&linkCode=df0&hvadid=658882618228&hvpos=&hvnetw=g&hvrand=13977935321389563953&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9011887&hvtargid=pla-2188631719356&psc=1&gclid=CjwKCAjwpJWoBhA8EiwAHZFzfv32cQCNquwx5ebX4VcSUg74BKb3w_g9DbeVxRA1aFOCpEfhBOQ8VRoC18gQAvD_BwE
