Elbow thru hull, 1 1/8" hose barb, small flange

Product Description

Introducing our versatile White Thru Hull Valve, engineered to deliver reliable, leak-proof performance in tight marine installations. Designed with a compact mushroom head of 1-7/8" diameter, this valve fits snugly where space is limited, without compromising on durability or function.

Crafted from UV-stabilized marine-grade plastic, it resists harsh sunlight, saltwater corrosion, and wear, ensuring long-lasting service above the waterline. The valve’s 1-1/8" ID hose barb perfectly fits many standard marine bilge hoses, with enough room for double hose clamps to guarantee a secure, leak-free connection even under pressure.

With 1-1/2" long threads, this valve accommodates hull thicknesses up to 1-1/8" and installs easily with the included 2-1/8" diameter mounting nut for a tight, secure fit.

Proudly made in the USA, this thru hull valve combines quality craftsmanship with marine-grade materials to provide dependable performance and peace of mind on every voyage.

Important: This plastic thru hull valve is designed for above-waterline use only. For below-waterline applications, please contact us with your specific needs—we'll help you find the best thru hull fitting for your boat.
