need help with refrigerant fittings
I'm retrofitting the controls in a big chiller (for an ice rink) and I need to add pressure transducers along with the existing gauges. The gauges have 1/4" male flare connections. The transducers are 1/4" male npt. Ideally, i'd like to find a Tee that can attach to the back of the gauge and accept the existing flared tube and the transducer.
While I'm dreaming, it would be good if it didn't project far behind the gauge. I have looked at grainger and mcmaster, and come away more confused than I went in. Surely I cant be the first person to do this. I'm not a refrigeration guy, though I'm working with one. I won't be able to reach him for a week, and I'm trying to get a jump on this. Your suggestions are welcome. jpb |

While I'm dreaming, it would be good if it didn't project far behind the gauge. You might look at a Swagelok catalog. Getting from 1/4" flare to 1/4" NPT will take some adapters, but I think it can be done. If brass is usable (not with ammonia) Weatherhead hydraulic fittings might be an option, but a quick keyword search of their website made it clear the hunt will be a long one. Good luck, bob prohaska I have looked at grainger and mcmaster, and come away more confused than I went in. Surely I cant be the first person to do this.

I have decided, instead, to do it the "right" way, and make up short flared female - female tubes to connect the gauges to the tees. More trouble but easier to put things where they need to be. Still, it's surprising that this isn't a more common part. |

The trick is plumbing is measured from the effective ID of the pipe, refrigeration is measured by the real OD of the tube. Jon |

There is a Harbor Freight brass 1/4 inch T fitting with 2 npt "sockets"
sticking out the sides & 1 flange fitting on the bottom (or top) in the next room that's served well. If there's a Harbor Freight store handy, a trip there might be worth while for you. Also, the Ace stores can be useful. Costly though.
