We got this badly needed part for our RV in excellent time. It was also packed very well. Show supplier cares about excellent service. Installed easily. Just wish I had noticed the change from my old regulator. Requires 1/4" flanges pig tail recommended with it. That was my fault. Again, it's nice to do business with a supplier who cares and respects expedited customer service at no additional cost.

This regulator is the most recommended regulator on the market by RV repair folks. It works well and is fairly easy to install.

So far so good with this Regulator. I hope it last longer than my original regulator. I went with a completely different brand with this one.
