When it comes to marine plumbing and water flow systems, thru-hull fittings are one of the most critical components on your vessel. These fittings allow water to safely pass through the hull, supporting everything from engine cooling to livewell intake to waste discharge.
At Hydrasearch Company LLC, we manufacture and supply Buck Algonquin marine hardware, including our trusted line of thru-hull fittings, proudly made to withstand the harshest marine environments. Whether you’re a boatbuilder, marine technician, or DIY boat owner, this guide walks you through proper installation and ongoing maintenance, ensuring your vessel stays safe and reliable on the water.
Why Choose Buck Algonquin Thru-Hulls?
Our Buck Algonquin thru-hulls are engineered with quality, safety, and longevity in mind. Available in naval bronze, stainless steel, and composite, our fittings are precision-machined and built to meet the high demands of both recreational and commercial vessels.
- Bronze Thru-Hulls: Perfect for below-waterline installations, corrosion-resistant in saltwater, and ABYC-compliant when paired with a seacock.
- Stainless Steel Thru-Hulls: A sleek, durable option for above-waterline use.
- Composite Thru-Hulls: Lightweight and corrosion-free, great for above-waterline or interior applications.
Backed by decades of marine hardware expertise, Buck Algonquin thru-hulls are trusted by boatbuilders and OEMs across the industry.
Thru-Hull Installation: Best Practices
1. Choose the Right Material
For below-waterline installs, we always recommend our bronze thru-hulls. For above-waterline ventilation or discharge, stainless steel or composite may be used.
2. Test Fit and Plan Access
Dry-fit your thru-hull before committing. Make sure it sits flush with the hull and allows easy access to the inside for hoses and shutoff valves.
3. Pair with a Buck Algonquin Seacock
Every below-waterline fitting should be installed with a proper seacock. Our Buck Algonquin seacocks are designed to pair seamlessly with our thru hulls, providing a watertight and secure shutoff solution.
4. Use Marine-Grade Sealant
Apply a high-quality marine sealant around the thru-hull flange and tighten carefully. Don’t overtighten, you want a tight seal, not a starved bond.
5. Reinforce with Backing Plates
Use a fiberglass or marine plywood backing plate to strengthen the installation and reduce stress on the hull.
Maintenance Tips to Maximize Lifespan
Routine Inspection:
Check all thru-hulls, especially bronze models, for signs of corrosion, dezincification, or seal failure. Our Buck Algonquin bronze castings are made to resist these issues, but regular inspections ensure longevity.
Operate Seacocks:
Exercise all valves at least every few months. A stuck seacock during an emergency can be disastrous.
Check Hose Clamps:
Ensure tight, rust-free stainless-steel clamps. For below-waterline, double-clamping is best practice.
Winterization:
Drain or flush with antifreeze to protect against freeze damage, especially in colder climates.
