When you’re on the water, there’s no room for compromise. Reliability, durability, and performance aren’t optional—they’re essential. That’s why boaters around the world trust Buck Algonquin marine products, proudly manufactured by Hydrasearch.

Designed for marine performance

Buck Algonquin has built a reputation for quality, durability, and engineering precision. Every product is designed with a single goal in mind: keeping your vessel operating safely and efficiently.

Positive flow Intake Filters

Manufactured from solid bronze, our intake filters feature removable, surface-mount grates. The 45-degree perforated openings allow superior water flow, ensuring your systems operate at peak efficiency.

Arctic Steel Strainers

For unmatched corrosion resistance, our Arctic steel filters are manufactured from duplex 2205 stainless steel. They deliver exceptional durability while keeping the engine room clean, functional, and reliable.

Transmission Couplers

We manufacture a complete line of transmission couplings for leading models such as ZF, Twin Disc, and BorgWarner. Available in solid, split, and tapered designs with multiple sizes and bolt-hole configurations, these couplings are engineered to fit and perform.

Ball valves and seacocks

Our low-profile bronze marine ball valves and seacocks come with stainless steel handles in sizes ranging from ⅜ inch to 4 inches. Each includes a drain plug and a grounding screw, engineered for maximum reliability.

Thru-hulls and hose fittings

These fittings, designed to mate seamlessly with our valves, ensure a secure connection. With full-length barbs on the hose nipples, hoses grip more effectively—requiring fewer clamps, saving you money, and improving safety.

Competitive pricing for 2025

In 2025, we’ve adjusted pricing across our entire range of plumbing fittings to deliver even greater value without compromising quality.
