Use End Caps to attach to the end of 1/2" poly tubing (.700" OD or .710 OD), or .700 soaker hose.
The cap unscrews for easy flushing and draining of poly tubing or soaker hose for winter.
Compression fittings require no glue.
This fitting also had male hose threads on both ends. So you can screw a female end on to it, for easy removal of your hose. Instead of trying to pull the hose out.
