The Schedule 40 PVC Combination Tee (Slip x Slip x FPT) is the professional's choice for installing sprinklers along a rigid pipeline. Designed with two slip sockets to connect sections of Schedule 40 PVC Pipe, it features a Female Pipe Thread (FPT) outlet on the branch (top) side. This allows you to screw in a threaded riser or swing joint directly into the mainline without needing extra adapters.
This configuration is most commonly used in irrigation systems to install Sprinkler Risers or threaded nipples directly into a main water line. By eliminating the need to glue in a separate tee and threaded bushing, this single unit saves space, installation time, and reduces the risk of leaks.

This fitting requires both solvent welding and thread sealing.
Step 1: Glue the Run
Clean, prime, and glue the PVC pipe into the two slip sockets on the run of the tee using PVC Glue. Ensure the threaded outlet faces the correct direction (usually up) before the glue sets.
Step 2: Prep the Riser
Apply thread seal tape to the male threads of your riser or nipple.
Step 3: Thread the Branch
Screw the riser into the center FPT outlet. Hand tighten, then give it a final quarter-turn with pliers. Tip: It is often easier to screw the riser in after the tee is glued to the pipe to ensure vertical alignment.
