Spears 450-005 – Frequently Asked Questions
1) What sizes does the Spears Schedule 40 PVC MPT plug come in?
The Spears 450 series PVC plug is offered in 1/2 inch (450-005), 3/4 inch (450-007), 1 inch (450-010), 1-1/2 inch (450-015), 2 inch (450-020), and 4 inch (850-040). Note the 4 inch carries an 850 prefix rather than 450, so order by that number if you are pulling a large-size plug.
2) Does this PVC plug thread into a female socket fitting or does it glue in?
It threads. The Spears Schedule 40 plug has a male pipe thread (MPT) end, so it screws into a female-threaded port, an FPT tee branch, a threaded coupling, or a threaded bushing. It will not solvent weld into a slip socket. If your open port is a plain socket hub, you need a socket plug or cap instead.
3) Can I use a PVC plug instead of a brass or galvanized plug on an irrigation manifold?
Yes, and it is the common choice where corrosion is the concern. PVC will not rust or scale the way a galvanized plug does in buried or wet-box irrigation service, and it matches the material of the PVC fitting it threads into, so you avoid dissimilar-material joints. It is also lighter to handle in bulk. Where you need a metal plug is high-mechanical-abuse or high-temperature service, which is outside what Schedule 40 PVC is intended for.
4) How do I seal a PVC MPT plug so it doesn't leak?
Use PTFE thread tape or a PVC-compatible thread sealant on the male threads, then hand tighten and go one to two turns past with a strap wrench. Do not over-torque. NPT threads are tapered, and the most common failure with a plastic plug is splitting the female fitting by cranking on it. Never use a pipe wrench on the plug body.
5) What is the difference between a PVC plug and a PVC cap?
A plug goes inside the fitting: it is male threaded and screws into a female port. A cap goes over the outside of a pipe end. The Spears 450 series is the plug, with an MPT end, so pick it when you are closing off a threaded branch on a tee, a manifold port, or a threaded bushing. If you are closing the end of a run of bare pipe, you want a cap instead.
6) Can I use this PVC plug on a hot water line?
No. Schedule 40 PVC is a cold water and ambient-temperature material, and pressure capability falls off sharply as temperature rises. For hot water or elevated-temperature process lines, use a CPVC fitting rated for that service, not a PVC plug.
7) Is this plug sold individually or only by the case?
The Spears Schedule 40 PVC MPT plug is packed 300 each per case, which is the bulk pack aimed at contractors and distributors running volume work. If you are buying to stock a truck or a service department, that is the unit you are working from.
