Connect your drip tubing or dripline to your water source with the 1/2 in. X 3/4 in. FHT Compression Swivel Adapter. Designed for convenience, the built-in swivel keeps the tubing from bending and kinking when installing the adapter in place. Threads onto a hose bibb or garden hose on one end; 1/2 in. supply tubing inserts into the compression ring on the other end, where an internal barb compresses the tubing for a watertight fit. Filter washer inside screens out particles. Compression swivel adapter is made of acrylonitrile butadiene styrene (ABS) treated with UV inhibitors to prevent cracking.
