Tanks being a "closed" system, vents provide for the necessary air flow in and out of the tank to compensate for changes in liquid level inside the tank during filling or use.
• Applicable for fuel, water, or waste tanks
• Compensate for changes in tank air pressure due to diurnal temperature related expansion and contraction
• Prevent vacuum build-up during use, which can disrupt fuel or water delivery
• Help prevent fuel spills, blow-back, and ensure fumes vent outboard instead of inside the boat
• Integral 5/8" hose barb securely connects vent hose
• Constructed of chrome plated die cast zinc
