Professional Grade Watertight Drainage for Saltwater Environments

Engineered for extreme durability in the open water, the AIROW MARINE Snap-Tite Drain Plug provides a fail-safe, vibration-proof seal for your vessel. Utilizing a high-leverage 304 Stainless Steel cam-action T-handle and solid brass internal hardware, this plug is designed to withstand harsh saltwater conditions without seizing or rusting.

  • Precision Expansion: The heavy-duty neoprene rubber body expands uniformly when the lever is snapped down, creating a high-pressure seal against the drain tube walls.
  • Corrosion-Proof Materials: Marine-grade 304 SS and brass components ensure long-lasting performance in both freshwater and saltwater.
  • Universal Application: Ideal for transom thru-hull drainage, live bait wells, ice chests, and bilge systems.
  • Multiple Sizes: Available in 3/8", 1/2", 5/8", 3/4", and 7/8" diameters to fit standard marine drain ports.

Whether you are replacing a worn transom plug or outfitting a new bait well, AIROW MARINE hardware delivers the reliability required for offshore use.

Frequently Asked Questions

Will this plug hold securely during high-speed hull vibration?
Yes. The Snap-Tite cam mechanism is engineered to mechanically expand the high-density neoprene plug against the walls of the drain tube. This creates a friction-based, vibration-proof seal that will not back out or loosen in rough water.
Is the metal hardware susceptible to rust in saltwater?
No. We utilize a combination of 304 Stainless Steel for the lever and solid brass for internal components. These materials are specifically selected for their electrochemical stability in marine environments to prevent seizing and corrosion.
How do I ensure I select the correct size for my boat?
You should measure the internal diameter (ID) of your drain tube or baitwell opening. Our plugs are available in precision increments (3/8", 1/2", 5/8", 3/4", 7/8") to provide the exact compression needed for a 100% watertight fit.

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. 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.
