## 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

### ⭐⭐⭐⭐ Review
*by E***O on 31 July 2023*

Se ve un producto con nivel adecuado de calidad, solo que la cubierta exterior de material sellante se ve muy rigida, parece mas una arandela de metal que un dispositivo de sellado que pueda amoldarse a superficies imperfectas, que es lo que debiera ser, de lo contrario no seria mejor que la propia conexión a a sellar. Pero les daré el beneficio de la dudad y que el tiempo y uso lo diga.
