The Hose x 1/4" Compression Adapter is the professional standard for starting a micro-drip system directly from a garden faucet or hose thread source. Unlike barbed fittings that can be difficult to insert, this compression adapter allows you to simply twist your 1/4" poly tubing into the fitting for a secure, high-flow connection (up to 30 GPH). To protect your micro-emitters from damage caused by high city water pressure, we strongly recommend installing a pressure regulator immediately upstream of this fitting.
Whether you are watering deck containers or vertical garden walls, this is one of the most reliable irrigation fittings for transitioning from a heavy-duty supply line to precision 1/4" distribution lines. The compression design ensures a watertight seal that handles temperature fluctuations better than standard friction-fit barbs.
Review these specs to ensure compatibility with your tubing and faucet.

Follow these steps for a leak-proof connection.
Step 1: Prep the Tubing
Cut your 1/4" poly tubing squarely. For the easiest insertion, cut the tip of the tubing at a slight 45-degree angle.
Step 2: Insert and Twist
Push the 1/4" tubing into the compression end while twisting the tubing. You will feel it "bite" into the internal ring. Keep pushing until the tubing hits the internal stop.
Step 3: Connect to Faucet
Ensure the internal rubber washer is flat, then thread the FHT end onto your spigot, timer, or manifold. Hand-tighten only.
Step 4: Verify the Seal
Turn on the water and check for leaks. If the tubing pulls out, it wasn't pushed in far enough; re-insert with a firm twisting motion.
