Ensure optimal fuel system performance with the AIROW MARINE 90-Degree Tank Vent. Engineered from forensic-grade 316 Stainless Steel, this vent is purpose-built to survive the brutal corrosive reality of saltwater environments.

Precision Manufacturing Features:

  • Mirror-Polished Finish: Expertly fine-ground to a high-luster finish that complements luxury yacht aesthetics.
  • Space-Saving Geometry: The 90-degree elbow design allows for efficient venting in tight compartments and shallow hull spaces.
  • Universal Connection: Features a 16mm (5/8") barbed hose connection for secure fuel, gas, or water tank ventilation.
  • Seamless Installation: Threaded body design requires no drilling or welding, including a high-compression rubber gasket for a watertight seal.

Frequently Asked Questions

Will this vent corrode or pit in saltwater?
No. Visual forensics confirm the use of high-grade AISI 316 Stainless Steel with a mirror-polished finish. This material is specifically alloyed with molybdenum to resist chloride pitting and corrosion in harsh marine environments.
Is the 90-degree angle better than a straight vent?
The 90-degree geometry is engineered for modern hull designs where space is limited. It allows the hose to run parallel to the hull or deck, preventing kinks in the 16mm hose and ensuring optimal airflow.
What is the exact hose size requirement?
This vent is designed for a 16mm (5/8 inch) Inner Diameter (I.D.) hose. The barbed fitting has an Outside Diameter (O.D.) of 16mm to ensure a high-friction, airtight seal when secured with a marine-grade hose clamp.

Our Roots

Hong Kong Based, 8 Years of Expertise

The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories.

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
