The 1" Easy Loc x 1" MPT Adapter is the essential link between your water source and your large-diameter distribution line. Designed to connect 1" Poly Tubing directly to any 1" Female Pipe Thread (FPT) component—such as a filter, pressure regulator, or PVC valve—this fitting creates a solid, high-flow transition point.
Part of our professional line of irrigation fittings, the Easy Loc (Perma-Loc) design utilizes a locking nut that screws over the tubing to compress it against the barb. This ensures a secure connection that can handle the volume of a 1" system. Unlike glued PVC fittings, this adapter allows you to easily disconnect the tubing from the threaded component for maintenance or winterization.
Connects 1" Tubing to 1" Threaded Components.

Proper installation ensures a leak-free system.
Step 1: Apply Tape
Wrap thread seal tape 2-3 times around the 1" male threads. This is critical for preventing leaks at the threaded connection.
Step 2: Connect Threads
Screw the adapter into your 1" FPT valve, filter, or fitting. Hand-tighten firmly. Do not over-tighten with a wrench.
Step 3: Prepare Tubing
Cut your 1" poly tubing squarely. Rotate the locking nut on the adapter backwards to expose the barb.
Step 4: Lock it Down
Push the tubing onto the barb until it hits the stop. Twist the locking nut forward over the tubing to seal the connection.
