## Questions & Answers

**Q: Can I use this long hose to connect to a propane tank instead of Natural Gas?**

A: Firmans website

**Q: Can I connect 2 of the 25’ hoses together?**
A: Yes you can connect more than one

**Q: What size are the connections on either end?**
A: Read their specs. 1/2" quick connect male on supply end with 1/2" female NPT fitting adapter.  1/2" female flare fitting on generator end with 1/2"/3/8" flare coupling fitting for generator connection.

exact fit

### ⭐⭐⭐⭐⭐ Works perfectly with the Firman generator.
*by F***L on January 24, 2023*

I purchased a Firman generator from Costco and purchased this hose to hook it up to natural gas. It is very durable, the fittings work well and it is long enough to allow placement of the generator further away from the home.

### ⭐⭐⭐⭐⭐ High Quality Product
*by J***. on April 20, 2025*

High quality product which includes all necessary fitings
