## Questions & Answers

**Q: What is the lifespan of these connectors?**
A: Usally my hoses gets holes before the connectors give out.

**Q: You carry 3/8**
A: These are for a 3/8" air line if that's what you're asking? The Fittings/couplers themselves are marked style "M"

**Q: Are these water tight?**
A: I bought this pack from Harbor Freight specifically to use for water lines at residential pressure levels (my home is 90-120psi), and the connection was water tight for me.

**Q: Can these handle air and steam?**
A: I do not know if they will handle steam.  I bought them for use with an air compressor -up to 300 psi.  I have had no problems with them.  Make sure to use teflon tape on any threaded connections.
