## Questions & Answers

**Q: Are these molded with npt, bspp or bspt threading?**
A: Hi! This is G3/4 threading, this means it is british standard, BSPT. But from our experience, it can fit into NPT threads if some teflon tape is applied and if your installation doesn't involve high pressure. Thanks for your question!
