T-H Marine ODT-1 Overflow Drain Tube - Straight, 12 Inch, Fits 1-1/8 Inch Thru-Hulls

The T-H Marine ODT-1 is a straight, push-in overflow drain tube designed to plumb a livewell or baitwell using a single thru-hull fitting for both overflow control and draining. Instead of reaching into the water to pull a drain plug, the operator simply lifts the tube out from the top to begin draining, then re-inserts it to restore the overflow seal. The tube features a tough, flexible vinyl plastic end that inserts directly into the opening of a 1-1/8 inch T-H Marine thru-hull fitting, connected to a standpipe made of white PVC tubing. This push-in style seals more tightly than many other overflow designs on the market while remaining easy to remove for draining.

The ODT-1 is built from marine grade PVC construction for long service life in a wet boat environment. It measures 12 inches in length and is intended to drain straight through a floor-mounted thru-hull (the companion ODT-190 is the 90 degree version for draining through a side wall). It fits all T-H Marine 1-1/8 inch thru-hull fittings. A matching filter screen (ODTS-1) is sold separately for those who want to add filtration at the drain opening.
