T-H Marine 12" Push-In Overflow Drain Tube – 90°, 1-1/8" Thru-Hull

Angled Overflow Drain Control for Tight Livewell Installations

The T-H Marine 12" 90-degree push-in overflow drain tube is built for livewell and baitwell setups where a straight standpipe won’t fit — the 90° elbow lets you route the overflow horizontally or at an angle when vertical clearance is limited. Like all T-H Marine push-in drain tubes, operation is simple: insert the flexible vinyl end into your 1-1/8" T-H Marine thru-hull fitting to hold your water level, pull it out to drain.

The 12" white PVC standpipe can be trimmed to your preferred overflow height, and the 90° elbow keeps the tube tucked neatly inside the tank when space is at a premium.

Key Features

• 90° elbow design — routes the standpipe horizontally or at an angle for installations with limited vertical clearance
• Push-in design — flexible vinyl end inserts directly into T-H Marine 1-1/8" thru-hull fittings; no tools required
• Simple drain operation — insert to hold water level, remove to drain by gravity
• 12" white PVC standpipe — suited for shallower livewell and baitwell tanks
• Trimmable to length — cut the PVC tube to match your tank depth or preferred overflow height
• Fits all T-H Marine 1-1/8" thru-hull fittings

Installation Notes

• Requires a T-H Marine 1-1/8" thru-hull fitting (sold separately) — see the T-H Marine 90° Thru-Hull Fitting for a compatible option
• The 90° elbow allows horizontal or angled routing inside the tank — ideal when the livewell lid or structure limits vertical standpipe height
• Insert the flexible vinyl end into the thru-hull opening to seal; pull out to drain
• Trim the PVC standpipe to your desired overflow height using a standard pipe cutter or saw

Best For

Livewell and baitwell installations where vertical clearance inside the tank is limited — such as tanks with low lids, internal structure, or tight compartment fits. The 90° elbow keeps the standpipe from interfering with the tank lid or aerator components. If your installation has full vertical clearance, the T-H Marine 12" Straight Overflow Drain Tube is the simpler option. For a longer standpipe with a built-in screen, see the T-H Marine 18" Overflow Drain Tube with Screen.

Parts Desk Insights

Recommend the 90° version when a customer mentions their livewell lid hits the standpipe, or when the tank has internal structure that blocks a straight tube. It’s also the right call for any installation where the thru-hull exits at an angle that makes a straight standpipe awkward. Confirm the customer has a T-H Marine 1-1/8" thru-hull before selling — fitting size is the critical compatibility check. If they need a longer tube or a screen, step them up to the 18" version with screen. Pairs naturally with the T-H Marine 90° Thru-Hull Fitting.
