It works as its intended. That’s what I bought it for. I hope it works as long as the old one.

Only worked perfectly for 6 months, should last out to a suggested replacing of 20 years. Contact with manufacturer suggested warranty through place of purchase, Amazon has only a 30 day policy on this product. This is a highly regarded quality product by most gas suppliers who would warranty if purchase was through them.

Purchased this to replace a regulator that failed after 10 years. Input/output threads were the same and it was rated for the same pressure output. Took less than 10 minutes to replace and test.
