What is the difference between FIP and MIP fittings?

A MIP fitting is threaded on one side, while a FIP fitting is threaded on both sides. A MIP has male threads that screw into the female connections of other plumbing fixtures or equipment, while a FIP has female connections that are designed to be screwed into the ends of pipes.

Which type of fittings are used for poly pipe?

PVC fittings are plastic based fittings commonly used with Polyethylene Tubing. Galvanized Steel fittings are non-corrosive and are rust-resistant which works well with water applications.

Can you use compression fittings on poly pipe?

Compression fittings are ideal to be used with annealed copper, aluminum, PEX, polyethylene and nylon tubing that is manufactured to CTS (Copper Tube Size).

What is FIP adapter fitting?

Simply, FIP is pipe that is threaded on the inside. As a female, it accepts the male pipe, which is threaded on the outside. The male end is twisted inside the female until it is snug. In order to keep a proper seal, Teflon tape is needed around the male threads.

Is NPT compatible with FIP?

Most pipe thread types are not interchangeable. NPT, MIP, and FIP work together but do not mate with any other types.

Are MIP and NPT the same?

Yes, NPT (national pipe thread) has the same thread dimensions as an MIP (male iron pipe) and FIP (female iron pipe).

Can you use PEX fittings on poly pipe?

PB has the same outside diameter as PEX of the same nominal size, but outside diameters differ slightly between the tubing types. This means that you should not use PEX fittings on polybutylene, but that you can use PEX crimping rings and PEX crimping tools on barbed PB connections.

Can I use brass ferrule on plastic tubing?

Brass ferrules are normally used on copper tubing and can cut into the soft plastic supply line.

Do you use Teflon tape on FIP fittings?

Don’t use Teflon tape, Teflon paste or pipe dope. Do use a sealant. Teflon tape, Teflon paste and pipe dope is intended for metal pipe and fittings. Metal to metal fitting joints are more difficult to tighten than plastic; the surfaces tend to gall without the aid of such lubricants as Teflon or pipe dope.
