NPT stands for National Pipe Taper. It's a standard thread type used for pipes and fittings, where the taper of the threads helps create a seal. This plug uses a 3/4 inch size of that standard.

What are these plugs used for?

These plugs are typically used to seal off unused threaded ports on engine blocks, intake manifolds, or other engine components. They provide a clean and secure way to close off openings.

Does the chrome plating offer any functional benefit?

Yes, the chrome plating helps protect the steel plug from rust and corrosion, ensuring a reliable seal over time, especially in the engine bay environment.

About this part

Product Details

When you're working on your engine, sometimes you need to seal off a port or a threaded opening. These Moroso pipe plugs are designed for just that. They have a standard 3/4 inch NPT thread, which is a common size for many engine block or intake manifold ports. The chrome plating not only gives them a clean look, but it also helps resist corrosion, keeping them sealed tight for the long haul.

This is a well-built set of two plugs. They're made from solid steel and then chrome plated. You'll find these are a popular choice for builders who want a neat finish on their engine components. Just thread them in where you need them, and they'll do their job sealing off that opening.
