Conbraco/apollo Seacocks
When it comes to protecting your vessel from catastrophic flooding, Conbraco/Apollo bronze sea flange ball type valves were developed to replace older style marine seacocks. These seacocks represent a modern evolution in marine through-hull safety, combining the reliability of traditional seacocks with the smooth operation and durability of precision ball valve technology.
Why Apollo Seacocks Stand Out in Marine Applications
An 85-5-5-5 bronze ball type valve developed to replace plug and other types of sea cocks in the marine industry, Apollo seacocks offer several advantages over traditional gate-style seacocks. Chromium-plated bronze ball with RPTFE seats for smooth, reliable operation, making them less prone to seizure than older designs. Stainless steel handle and hardware for corrosion resistance ensures these valves can withstand the harsh marine environment season after season.
The full-flow design is particularly important for engine cooling intakes and livewell systems where unrestricted water flow is critical. The Apollo sea flange valves provide long-lasting performance and value, with features specifically engineered for the demands of marine service. Winterizing drain plug and bonding screw included, addressing the practical needs of boat owners in seasonal climates and ensuring proper electrical grounding to prevent galvanic corrosion.
Construction and Quality Standards
Apollo valves are designed, engineered, cast, machined, assembled, and tested in ISO-registered, state-of-the-art facilities in the Carolinas. This vertical integration means Conbraco/Apollo controls every aspect of production, from the bronze casting through final assembly. Compact, UL-listed design made in the USA ensures these seacocks meet rigorous safety standards for marine installations.
The company offers multiple product lines including their Full Flow series and Economy Sea Flange valves in sizes ranging from 3/4" to 4", along with various shut-off valve configurations. The 78-series and 77-series represent their most popular seacock models, widely specified by boat builders including Tracker, Rinker, and other major manufacturers.
Installation and Maintenance Advantages
Unlike simple ball valves threaded onto through-hull fittings, Apollo flanged seacocks mount securely to the hull with a proper flange base, providing structural support that protects the through-hull fitting from impact damage. The ball valve mechanism requires minimal maintenance compared to tapered plug designs, though periodic lubrication and operation keeps them functioning smoothly. The included winterization drain allows easy system preparation for cold storage without disassembling plumbing connections.
With nearly a century of valve manufacturing expertise dating back to the 1928 formation of Consolidated Brass Company, Apollo brings industrial-grade flow control technology to the marine market. Whether you're replacing aging seacocks or outfitting a new vessel, Apollo's combination of corrosion-resistant materials, reliable sealing technology, and American manufacturing makes them a trusted choice for below-waterline safety.
