The fuss-free way to add a supply line to your drip system water source is with the 1/4 in. X 3/4 in. FHT Compression Swivel Adapter. Thread adapter onto a hose bibb or garden hose on one end, and insert 1/4 in. supply tubing or dripline into the compression ring, where an internal barb compresses the tubing to hold it in place. The built-in swivel allows you to screw or unscrew the adapter without kinking the tubing. Filter washer inside screens out particles. The compression swivel adapter is made of acrylonitrile butadiene styrene (ABS) treated with UV inhibitors to prevent cracking.
