Product Feature
Excellent Corrosion Resistance & Durability
The main body is made of high-purity forged brass, which abandons the defects of easy rust and short service life of iron and stainless steel plugs. It has excellent resistance to seawater salt spray corrosion, oil pollution and high humidity oxidation, and can maintain stable structural performance in long-term marine harsh environments.
Super Tight Sealing Performance
Matched with high-quality NBR oil-resistant rubber sealing ring, it adopts mechanical compression expansion sealing structure. After manual tightening, the rubber ring expands evenly and fits closely with the inner wall of scupper hole, achieving 360° full-circle seamless sealing. It can effectively block seawater backflow, deck water leakage and oil spill leakage, meeting the watertight and oil-tight safety standards of marine drainage systems.
Easy & Fast Operation
Integrated design, no complex assembly parts. The whole installation and disassembly process does not require any professional tools, only manual twisting and tightening is needed to complete sealing and fixation, and reverse twisting can realize quick disassembly and drainage. The operation is simple and efficient, which greatly saves deck operation time and labor cost.
Excellent Corrosion Resistance & Durability
The main body is made of high-purity forged brass, which abandons the defects of easy rust and short service life of iron and stainless steel plugs. It has excellent resistance to seawater salt spray corrosion, oil pollution and high humidity oxidation, and can maintain stable structural performance in long-term marine harsh environments. The surface is finely polished, smooth and wear-resistant, not easy to deform and damage, realizing long-term reuse.
High Safety & Stability
The mechanical locking structure is stable and reliable, which is not easy to loose and fall off due to ship vibration and wave impact. It effectively avoids the safety hazards of water inflow and oil leakage caused by plug falling off, and meets the safety operation specifications of ship navigation, deck cleaning and oil spill prevention.
Product Application
Marine Vessel Field
It is widely used for deck scupper hole sealing of various ships, including commercial cargo ships, passenger ships, fishing boats, engineering ships, yachts etc. It is used for temporary sealing of drain holes during ship navigation, deck washing, rainwater accumulation prevention and oil spill leakage prevention, ensuring hull watertight safety.
Offshore Engineering Equipment
Suitable for drainage hole sealing of offshore platforms, offshore wind power supporting facilities, marine floating equipment and other offshore engineering equipment. It adapts to high-salt and high-humidity offshore working environment, and provides stable sealing protection for equipment drainage systems.
Shipyard & Marine Maintenance
Used for temporary sealing and protection of scupper holes during ship repair, docking, painting and maintenance. It can prevent dust, sundries, sewage and paint from entering the drainage pipeline, protect the pipeline system from pollution and damage, and facilitate ship maintenance operations.
Product Details
Structural Design
The product adopts four-in-one integrated structure, including brass upper fixed plate, adjustable expansion rubber sealing body and brass lower limit plate, equipped with manual twisting handle. The overall structure is compact and reasonable, with strong integrity and no loose parts. The central screw transmission structure realizes synchronous expansion and contraction of the rubber ring, with uniform stress and stable sealing effect.
Material Craftsmanship
The brass parts are forged and finely machined by one-time die-casting, no pores and no burrs on the surface. The sealing rubber ring is made of high-elasticity oil-resistant NBR material, which has good tensile resistance, aging resistance and deformation resistance, and can maintain stable elasticity after long-term compression.
Humanized Design
The top handle adopts anti-slip design, which is convenient for manual twisting and force application, and will not slip during wet operation. The streamlined appearance avoids scratching deck operators and equipment. The lightweight design reduces the load of hull accessories and will not affect the overall load and balance of the ship.

FAQ
Q: What is the core advantage of brass scupper plug compared with plastic and iron plugs?
A: Brass material has natural seawater corrosion resistance, no rust and no deformation, with a service life 3-5 times longer than iron plugs and far more durable than plastic plugs which are easy to age and crack. Matched with NBR rubber sealing ring, it has better sealing stability, can resist marine oil pollution and high temperature environment, and is more suitable for long-term marine operation scenarios.
Q: How to select the correct model and size?
A: You only need to measure the inner diameter of the ship deck scupper hole, and select the corresponding product according to the applicable aperture range in the parameter table. For example, if the aperture is 60mm, you can choose IMPA 232483 (65-85mm) model. If you have special aperture sizes, we can provide customized size processing services.
Q: Will the plug loose or leak after long-term use?
A: The product adopts mechanical compression locking structure. After manual tightening, the rubber ring is fully expanded and locked, which will not loose due to ship vibration and wave impact. The high-quality NBR rubber ring has excellent anti-aging and anti-deformation performance, and can maintain zero-leakage sealing effect for a long time under normal use.
Q: Is professional tools and professional operation required for installation?
A: No professional tools and professional skills are required. Just insert the plug into the scupper hole, manually twist the top handle until slight resistance is felt, and the rubber ring can be expanded to complete sealing and fixation. Reverse twisting can realize quick disassembly, which is convenient for daily use and maintenance.
Q: Can the product be used in oil-polluted seawater environment?
A: Yes. The sealing part is made of oil-resistant NBR rubber material, which can resist the erosion of ship fuel oil, lubricating oil and various oily sewage. It will not swell, harden or fail due to oil pollution, and is especially suitable for ship oil spill prevention and sealing operations.
