The Schedule 40 PVC Threaded Cap is the reusable solution for terminating threaded pipe runs or closing off unused ports on a manifold. Unlike a glued slip cap, this fitting features Female Pipe Threads (FPT) that screw onto any standard PVC fitting or male adapter.
This design is ideal for creating "clean-out" points at the end of a mainline or temporarily capping off a sprinkler riser for future expansion. Manufactured by Dura Plastics, these caps provide a water-tight seal when used with thread tape, yet remain easy to remove for winterization or system flushing.
Match the cap size to the Male Thread you are covering.
| Size | Connection Type | Dura MPN |
|---|---|---|
| 1/2" | 1/2" Female Pipe Thread (FPT) | 448-005 |
| 3/4" | 3/4" Female Pipe Thread (FPT) | 448-007 |
| 1" | 1" Female Pipe Thread (FPT) | 448-010 |
| Material | Schedule 40 PVC (White) | |
| Standards | ASTM D-2466, NSF-PW | |
Secure connection without glue.
Step 1: Prep the Threads
Clean the male threads of the nipple or fitting you are capping. Apply thread seal tape (Teflon tape) wrapping 3-4 times in a clockwise direction.
Step 2: Install Cap
Screw the cap onto the taped threads by hand until snug.
Step 3: Tighten
Use a wrench or pliers to turn the cap one additional half-turn. Do not overtighten, as this can split the PVC cap.
Step 4: Pressurize
Turn on the water to test for leaks. If a drip occurs, tighten slightly more.
Ensure this matches your needs:
