Marine Plumbing Parts and Components
GEM offers a variety of Plumbing, Venting, and Fuel System products to ensure high quality and performance.
We now offer a COMPLETE lineup of composite marine fittings and valves. We have partnered with TruDesign, a well-established, 45-year-old New Zealand company. All of their design, tooling, and manufacturing is done in-house, which is important for the future of product expansion and innovation. We also chose TruDesign as a partner due to their extensive knowledge of the marine plumbing segment. They carry numerous ABYC, UL, and other certifications.
They are working with us to expand their product line with the help of our engineering team, and their tooling and manufacturing capabilities greatly benefit GEM and our ability to make our customer's boats better. We see this product line as the future of marine plumbing and we are excited to be part of it.
