What does Fipt, Mipt, Spig, and Slip mean and how do I know which one to use?

All PVC Fittings have connections that are called either Fipt (Female Threaded), Mipt (Male Threaded), Slip (Female Glue Joint), or Spig (Male Glue Joint). I will explain each one in detail below:

Fipt: This means the fitting is threaded on the inside (female) and will accept a threaded piece of pipe (male) of the same dimension.

Mipt: This means the fitting is threaded on the outside (male) just like the end of a piece of pipe. This connection must go to another fitting that is a Fipt (female) threaded. You cannot connect a Mipt Fitting to a piece of pipe without another fitting, since they are identical in configuration.

Slip: This is a smooth (not threaded) female fitting that will accept an unthreaded piece of pipe of the same size, which must be glued in.

Spig: This is a smooth (not threaded) male fitting that is made to go into another fitting that has a Slip connection of the same size, which must be glued in. A Spig fitting is the same as a piece of unthreaded pipe of the same size. You cannot connect a Spig Fitting to a piece of pipe without another fitting, since they are identical in configuration.

Schedule 40 Fittings Pressure Ratings

Schedule 40 fittings are rated on wall thickness. Due to this fact the pressure ratings for the size of fittings will vary. The pressure ratings are as follows:

Fitting Size

Pressure Rating

1/2" Schedule 40 Fittings

600 psi

3/4" Schedule 40 Fittings

480 psi

1" Schedule 40 Fittings

450 psi

1 1/4" Schedule 40 Fittings 

370 psi

1 1/2" Schedule 40 Fittings

330 psi

2" Schedule 40 Fittings

280 psi

2 1/2" Schedule 40 Fittings

300 psi

3" Schedule 40 Fittings

260 psi

4" Schedule 40 Fittings

220 psi

6" Schedule 40 Fittings

180 psi

8" Schedule 40 Fittings

160 psi
