The 3/4" Compression x 3/4" FPT Adapter is the perfect solution for transitioning from a rigid PVC system to high-capacity drip tubing. Designed with a 3/4" Female Pipe Thread (FPT) Swivel inlet, this adapter screws directly onto any standard 3/4" Male Pipe Thread (MPT) riser, nipple, or valve, allowing you to feed a 3/4" poly tubing line without using difficult glued connections.
This fitting is particularly useful for converting high-flow sprinkler zones to drip irrigation. As one of our most robust irrigation fittings, it features a heavy-duty internal compression ring that grips the larger .940" OD tubing securely, creating a reliable seal that handles the higher flow rates typical of 3/4" systems.
Verify your thread and tubing sizes.

Step 1: Check the Washer
Ensure the sealing washer is seated inside the threaded swivel end. This washer provides the watertight seal against the riser.
Step 2: Screw onto Riser
Thread the adapter onto your 3/4" Male Pipe Thread (MPT) fitting. Hand-tighten firmly until snug. Do not use a wrench, as this may crack the swivel nut.
Step 3: Connect Tubing
Cut your 3/4" poly tubing squarely.
Pro Tip: 3/4" tubing is stiff. Warm the end in the sun or hot water to make insertion much easier. Push the tubing into the compression end until it passes the internal resistance ring.
