T-H Marine ODT-290 Overflow Drain Tube, 90 Degree, Fits 1-1/2 Inch Thru-Hulls, 18 Inch with Screen

The T-H Marine ODT-290 is a push-in overflow drain tube built to plumb a livewell or baitwell through a single thru-hull fitting, serving as both the overflow and the drain. Instead of reaching into the water to pull a drain plug, the boat owner simply pulls the tube out from the top of the fitting to begin draining, then pushes it back in to reseal. The tube features a tough, flexible vinyl end that inserts directly into the opening of a 1-1/2 inch T-H Marine thru-hull fitting, sealing more securely than a conventional drain plug while remaining easy to remove.

This is the 90 degree version, engineered for draining through a side wall (the straight-tube version is intended for draining through the floor). It measures 18 inches in length and ships with the screen installed to keep debris out of the drain line. The tube and boot have an outside diameter of 1 5/8 inches, matching the 1-1/2 inch thru-hull it is designed to fit. Construction is all marine grade PVC for long service life in wet bilge and livewell environments.
