what is this ???

ScottMP

Timmie the Elder, will know for sure. Anyone else have an idea just what this is ?

My guess would be some sort of gas drip leg to remove moisture/liquid ?

We found this on an old gas hot water install.

buffer?

Even though most service lines in from the street are 1in around here, local gas company used to require 1.5in from the meter to the furnace. They claimed it provided a "buffer" against pressure loss during ignition.

I could never rationalize it working, but they had the final say on such things. If it did do as they say it probably was just covering up for poor piping out in their network :-)

I thought for a minute it might also contain some sort of dessicant but if so I'd expect side/bottom inlet and side/top outlet.

It's a filter

I've seen a few on old stuff. Took one apart and it had steel wool in it. My guess is some rusty dust in the gas was clogging the pilot orifice. I use ice maker water filters in the line to humidifiers when I get tired of picking the little clogs out of the humidifier orifice.

Yeah I have seen that before

Just like Dale, I found steel wool in the larger pipe. I asked an old timer from the gas utility and he said that they used to throw these on a house that was on the lowest (in elevation) tap from the street main.

Dale is right

it is a filter for the old gas which was very dusty. It can be removed now no longer needed.

right out of my National Fuel Gas Code Handbook (NFPA 54-1999.) This book has both the code, and interpretation, pictures, and examples in blue ink. Very handy. Guess I need a new version
