Built for dependable above-waterline plumbing, this rugged plastic thru-hull fitting features durable thermoplastic construction that helps prevent electrolysis and won’t rust, corrode, discolor, or contribute to hull streaking. The streamlined flange design also allows countersinking for a clean, flush installation wherever a smooth exterior finish is required.
Caution: Thru-Hull connectors are designed for installation above the water line only. NOT recommended for use below the water line.
