OATEY 31226 – Frequently Asked Questions
1) Can I use Oatey 31226 pipe joint compound on plastic threads like PVC or CPVC?
No. The 31226 gray pipe joint compound is not for use on plastic threads. It's made for sealing metal threaded connections. The compatibility list does name CPVC and PVC alongside aluminum, brass, copper and stainless steel, but the product's own feature list rules out plastic threads, so keep it to metal thread joints and use a plastic-safe thread sealant on PVC or CPVC threaded fittings.
2) What pressure and temperature can Oatey 31226 joint compound handle on a gas line?
On gas lines the gray compound is rated to a maximum working pressure of 3,000 PSI from -20 degrees F to 400 degrees F. On liquid lines it goes much higher: 10,000 PSI from -20 degrees F to 500 degrees F. Those are two different ratings, so size your application against the correct one.
3) Will this pipe dope harden in the joint so I can't break the union later?
No. The 31226 is a soft-setting compound that does not harden, so threaded joints stay serviceable and can be broken loose for maintenance. It also won't separate in the container, and cleanup is easy.
4) Is Oatey 31226 OK for steam and compressed air lines, or just water?
Water, air and steam pipe lines are all listed uses for this gray compound. The liquid-line rating runs to 500 degrees F and 10,000 PSI maximum working pressure, which is what covers hot water and steam service on metal threads.
5) Can I use this compound on galvanized and black iron threads in a mechanical room?
Yes, it's built for metal threaded connections, and the compatibility list covers aluminum, brass, copper and stainless steel. The gray compound stays soft so future disassembly of unions and valves is straightforward, and it cleans up easily off tools and hands.
6) How much compound is in the 1 oz Oatey 31226, and is that enough for a service truck or a whole job?
It's a 1 oz container, listed at 0.01 volume and 0.15 lbs product weight. That's a touch-up or single-repair size, good for a tool bag or a punch list item. If you're doping out a full gas or water rough-in, order the larger containers in the same gray compound rather than stacking 1 oz jars.
