Conbraco/Apollo Fuel Valves: Proven Flow Control for Marine & Engine Applications
When it comes to controlling fuel flow on a boat, generator, or small engine, the integrity of your shut-off valve is not a detail to overlook. Conbraco/Apollo has been engineering precision flow control products since 1928, and their fuel valves carry that same century-long commitment to quality into one of the most safety-critical components on any fuel system.
The 78-Series: Built Specifically for Fuel Service
Conbraco/Apollo’s marine fuel shut-off valves belong to their well-regarded 78-Series — bronze ball-type valves designed exclusively for fuel and oil service. The Apollo Fuel Shut-Off Valve has a bronze body with a chrome-plated bronze ball and a stainless steel lever. Every wetted metallic component is brass or cast bronze, making these valves naturally resistant to corrosion from fuel, condensation, and the harsh marine environment.
What sets the 78-Series apart in practical installation is the built-in “mounting ears” design. The quality bronze valve features “mounting ears” for quick, easy installation and positive mounting — allowing technicians and do-it-yourself boaters to surface-mount the valve securely without improvised hardware. The valve can also be used for bonding, an important consideration in marine electrical grounding systems.
Key Technical Features
- 400 psi service rating — well above typical marine fuel system pressures, delivering a meaningful safety margin
- Fast 90° on/off turn — the lever’s fast 90° on-off turn lets you quickly open or close the valve in an emergency or routine shutdown
- RPTFE seats and seals — RPTFE seats and seals provide chemical resistance compatible with gasoline, diesel, and other petroleum-based fuels
- Stainless steel lever and nut — its strength is further enhanced by the stainless steel lever and nut , resisting corrosion even in saltwater environments
- Surface-mount design with integrated mounting ears for positive, vibration-resistant installation
A Heritage of American Manufacturing
Two Detroit-based manufacturers of brass valves and fittings merged in 1928, and Conbraco Industries was created as a leading manufacturer of American-made flow control products for U.S. and international markets. Apollo valves are designed, engineered, cast, machined, assembled, and tested in ISO-registered, state-of-the-art facilities in the Carolinas. Apollo’s vertical manufacturing integration assures better quality control, better cost control, and the shortest delivery lead times possible.
That vertically integrated approach matters in the fuel valve category. Consistent material sourcing, in-house casting, and rigorous testing mean that every bronze valve leaving the facility meets the same dimensional and performance standards — critical when a valve failure in a fuel system can have serious consequences.
Available Sizes for Common Fuel Line Configurations
Conbraco/Apollo fuel shut-off valves are available in multiple NPT sizes — including 1/4", 3/8", 1/2", and 3/4" — to match the most common marine and small engine fuel line configurations. Whether you are plumbing a single outboard engine, an inboard/outboard setup, or a generator installation, there is a 78-Series valve sized for the job.
