PVC Male Adapter for 3 Inch Schedule 40 Pipe
This white PVC male adapter connects a 3 inch Schedule 40 spigot to a 3 inch male NPT thread. It is manufactured by Mueller Industries and supplied new as model 06366. The fitting is rated for gravity flow service only.
Temperature Range and Pressure Rating
The adapter handles fluid temperatures from minus 20 degrees to 140 degrees Fahrenheit under gravity flow conditions. It carries no seal in the box, so the installer must supply thread sealant or tape. The overall length is approximately 3 and 1/16 inches.
Suits Gravity Drain Lines Not Pressurised Systems
Plumbers and DIYers joining Schedule 40 PVC drain pipe to threaded metal or plastic fittings will find this part direct and code compliant. It is not designed for pressurised water supply, compressed air or hot water circulation loops. Buyers needing pressure rated joints or solvent weld sockets should select a different fitting type.

Questions about this item
Does the 3 in Schedule 40 PVC male adapter require periodic seal replacement?
The adapter ships without an included seal, so any required sealing method must be supplied separately and inspected during routine system checks.
What pressure limit governs continuous gravity-flow service?
The fitting is rated for gravity-flow maximum operating pressure only; it is not rated for pressurised applications.
How does the material handle constant exposure to 140 degrees F water?
PVC Schedule 40 is rated for continuous service up to 140 degrees F; sustained temperatures above that range risk softening and deformation.
