OATEY O31263 – Frequently Asked Questions
1) Can Oatey Great Blue pipe joint compound be used on plastic threads like PVC and CPVC, or is it only for metal pipe?
Great Blue works on both. It is rated for PVC, CPVC, ABS, polyethylene, polypropylene, iron, steel, copper and brass threads, up to and including 2 inch. That covers mixed-material jobs where you are threading plastic into a metal fitting, which is where a lot of thread sealants cause trouble.
2) Is Oatey 31263 joint compound approved for natural gas lines?
Yes, natural gas is one of the listed services, along with water, steam, air, caustics and dilute acids. On gas it holds up to 3,000 PSI across a -50 to +400 F range. On liquids the rating is 10,000 PSI from -50 to +500 F.
3) Will pipe joint compound attack PVC or CPVC threads?
Great Blue is formulated for use on PVC, CPVC and ABS as well as cycolac, polypropylene and polyethylene, so it is safe on those threads, unlike many general-purpose oil pastes that can stress-crack plastic. Keep it to threaded connections only, and to sizes 2 inch and under.
4) Should I use pipe joint compound or PTFE tape on threaded plumbing joints?
A paste compound like Great Blue lubricates the threads as it seals, so the joint pulls up tighter with less chance of galling, and it fills minor thread imperfections that tape bridges over. Great Blue is oil-based, non-hardening and non-separating, so the joint stays serviceable and can be broken later. Tape is cleaner to handle and preferred where an oil-based compound is not wanted. For threads over 2 inch, Great Blue is outside its stated range.
5) Can I use Great Blue on a steam line or a hot water heating system?
Yes. Steam is specifically among the listed services, and the compound is rated to +500 F on liquids and +400 F on gases, with a low end of -50 F for both. That covers steam and hydronic heating threaded joints as well as chilled and refrigerated lines.
6) Will Oatey Great Blue harden in the joint or in the can?
No. It is a flexible, non-hardening, non-separating, non-toxic paste with a uniform smooth consistency, so it brushes on without stirring and the joint can be taken apart later. It is also odorless and cleans up easily, which matters on occupied-building work.
7) How much product is in the Oatey 31263 can, and what is the part number for reordering?
Each can holds 16 oz of Great Blue pipe joint compound, Oatey part number 31263, shipping weight 1.3 lb. One MPN, no size or color options to specify, so it is a straightforward repeat-stock item for a truck or MRO shelf.
