Are you an avid boater looking for hardware that is a cut above the rest? Then Groco is the only name you need to know. The company was born in Baltimore in 1918, the time of the industrial boom when marine and automotive industries were growing extremely fast. The company’s founder, Angus Roy Gross, Sr., had a keen eye on innovation. He had many patents, the most distinctive of which were an ice shaver, combination lever, blow torch, and much more. However, in the late 1920s, Groco decided to focus on the marine industry. Now the company is recognized for its superior-quality water pumps, valves, fittings, hull scoops, raw water strainers, water pressure systems, and many other related marine products.
At Groco, they have always been committed to staying on the cutting edge of product development. From manual machining equipment many years ago to state-of-the-art CNC machining technology, Groco is constantly growing and improving to ensure ultimate customer satisfaction. Featuring a solid construction, Groco marine parts are proven to deliver outstanding performance and reliability. They will keep your vessel operating at its peak, improving your boating experience. Groco uses the finest materials while making their underwater hardware to guarantee it will hold up to the most demanding marine conditions. Whether you opt for stainless steel fittings or an aluminum hull scoop, rest assured you will make your engine room or hull look at its best for years to come.
Groco’s tradition of creating innovative designs is the main factor that distinguishes the company from the competition and allows it to take its place among marine industry leaders. Although the company has gained worldwide popularity for its pumps and hardware, it offers products that feature far more sophisticated designs. Tired of those clogged strainers in hard-to-reach places? Groco has you covered with top-notch strainers that can clean themselves on specific intervals. And how about a waste treatment system that will allow you to discharge waste legally in almost any place you are? Don’t want to go to the engine room to open or close seacocks?
