Buying Guide
- Port size and compatibility: Choose valve ports that match your hose or pipe diameters (1/4″, 3/8″, etc.) and the NPT or hose barb fittings used in your system.
- Material durability: Brass is common and corrosion-resistant for fuel lines; stainless steel offers higher durability in harsher environments.
- Detents and locking: Click detents or locking handles help keep the valve in the selected position during movement or vibration on the water.
- Flow path and purpose: Determine whether you need to connect two tanks to one engine, divert flow among three sections, or simply switch between sources with minimal pressure loss.
- Installation space: Compact valves fit tighter engine rooms or cockpit installations; ensure adequate clearance for operation and maintenance.
- Regulatory compliance: Look for valves that meet marine standards and are designed for fuel applications to ensure safety and reliability.
- Maintenance and accessibility: Some valves offer easier disassembly for cleaning or replacement of seals; consider accessibility for routine checks.
- Price versus value: While brass is standard, stainless options may cost more but provide longer service life in challenging environments.
