The 1/2" Compression x 3/4" FPT Adapter is the go-to fitting for converting an existing sprinkler system into a water-efficient drip zone. Designed with a 3/4" Female Pipe Thread (FPT) inlet, this adapter screws directly onto any standard 1/2" poly tubing system from a 3/4" Male Pipe Thread (MPT) riser, nipple, or valve.
Ideal for retrofitting garden beds or shrub areas, this fitting allows you to transition from rigid PVC pipe to flexible polyethylene tubing in seconds. As one of our most essential irrigation fittings for system conversions, it features a high-quality compression ring that locks the tubing in place for a permanent, leak-free seal.

Step 1: Check the Washer
Ensure the washer is seated inside the threaded swivel end. This washer provides the seal against the riser, so thread tape is generally not required (though a small amount can help if threads are worn).
Step 2: Screw onto Riser
Thread the adapter onto your 3/4" Male Pipe Thread (MPT) riser or nipple. Hand-tighten firmly until snug. Do not over-tighten with a wrench.
Step 3: Connect the Tubing
Cut your 1/2" poly tubing squarely. Insert it into the compression end of the adapter. Rock the tubing back and forth while pushing firmly until it passes the internal resistance ring (approx. 1/2" to 3/4" deep).
Ensure this adapter fits your system:
