2018 RETA Breeze May- June

Know when it is tight enough. Please read the instructions, some valves take packing, and some take O-rings to seal the stems from leaking. When it is tight it does not mean keep jamming on it until something breaks. In my opinion, packing nuts should be jammed crazy tight. ey need to be tight enough to keep the stem sealed and they should be serviced when you do your valve cycling. Also, very few valves do not have a back seat that I have found. Open it “snug” and then you should be able to service the packing on the valve. I use a little high temp grease or never-seize to keep the packing lubricated and sealing good. If you have any questions about valves, please contact your supervisor or take a photo and send it to anyone in your Chapter. If they can’t answer the question pop o an email to the email below and I will do my best to get it answered. Y’all be safe out there. If you have photos of an epic fail please pass them on to nh3fail@gmail.com the names have been changed to protect the guilty! PACKING NUT EPIc FAIl by Arlie Farley, CARO, CIRO, Farley’s Frigeration
