GROCO 1-1/2" 90° Hose Thru-Hull Fitting – Bronze

MPN: HTHC-1500-S

Built for strength, safety, and long-term reliability, the GROCO 1-1/2" 90-Degree Hose Thru-Hull Fitting is a premium marine plumbing component designed for tight installations where straight thru-hulls won’t fit. The integrated 90-degree elbow allows hose routing inside the hull without sharp bends, reducing hose stress and improving flow.

Manufactured from high-quality cast bronze, this thru-hull fitting offers excellent corrosion resistance in both freshwater and saltwater environments. It’s ideal for bilge pump discharge, livewell drains, cockpit drains, and other below- or above-waterline plumbing applications where durability is critical.

• Space-Saving Design: The 90-degree bend is ideal for installations near bulkheads or in shallow bilges, allowing the hose to run parallel to the mounting surface.

• Superior Material: Cast from high-quality bronze, providing excellent resistance to galvanic corrosion in both saltwater and freshwater environments.

• Secure Connection: Features a serrated hose barb designed to provide maximum grip for 1-1/2" ID marine hoses when used with double hose clamps.

• Flanged Base: The wide flange provides a large surface area for marine sealant to create a 100% watertight seal against the hull.
