Frequently Asked Questions
- Will the cap vibrate loose during high-speed transit?
- No, the high-grade rubber O-ring creates a friction seal, and the included deck key allows for high-torque tightening to ensure the cap remains secure even in heavy chop.
- How do I choose between the 38mm and 50mm sizes?
- This is determined by your internal hose diameter. The 38mm variant fits standard 1.5-inch marine hoses, while the 50mm variant is designed for high-flow 2-inch hoses common on larger yachts.
- Is 316 stainless steel really necessary for freshwater use?
- While 304 can suffice in freshwater, our 316 cast construction provides superior longevity against oxidation from harsh dockside cleaners and environment pollutants, making it a permanent 'buy it once' solution.

These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.
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.

Our products are built to power your voyage, while our packaging is designed to protect the purity of the blue sea.
