## Questions & Answers

**Q: will this work on brass air fittings?**
A: It should work.

**Q: Can i use this for joining pvc together?**
A: NO!

**Q: Why most reviews point out that their bottle had only half or less than half the amount of liquid?!**
A: Loctite 271 is an anaerobic sealant, which means it works in the absence of air. If the bottle was completely filled with no air, it would harden inside the sealed container. The bottle needs to be half empty in order for the product to still be a usable liquid when it reaches the consumer. Most reviewers are ignorant of this, and many other facts.

**Q: What is the expiration date?**
A: The two bottles I purchased have an expiration date of 4/2024. it has a shelf life of 2 years unopened and 1 year after openiing.
