Drain Plugs, Bulkheads, Kingstons, and Through-hulls

Stainless AISI 316 intake strainer thru-hull fittings (also known as “Kingston” strainers) designed with a built-in scoop or grill to filter out debris. Available in sizes from 3/8" up to 1-1/2", these thru-hulls mount on the hull exterior (typically at the bottom or side) to serve as water intakes for engine cooling, generators, air conditioning systems, or livewell pumps. The external scoop cover has slots/holes that face forward (for scoop types) or flush grids (for low-profile strainers), allowing water in while keeping weeds, trash, or marine life out. Made from rugged 316 stainless steel, they ensure maximum flow and corrosion resistance. Internally, they connect to your seacock or hose like a standard thru-hull. These strainers are essential for protecting pumps and engines from clogging, and their polished stainless appearance complements any hull.

• Material: AISI 316 stainless steel – corrosion-resistant in seawater, strong construction
• Sizes: 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2" thread/pipe sizes to match intake hose/valve requirements
• Design: Scoop/strainer head on outside (with grill openings), threaded thru-hull body, interior nut for mounting
• Function: Intake water for engines, gensets, air conditioners, bait tanks – strainer prevents entry of debris for reliable cooling and pumping

High-quality threaded thru-hull fittings made from AISI 316 stainless steel, available in a range of pipe thread sizes from 3/8" up to 2". These thru-hull connectors (sometimes called bulkhead fittings) feature a flange/head on one end and male pipe threads on the other, allowing secure installation through the hull or tank wall of a boat. Ideal for intake or discharge ports, they pair with seacocks, ball valves, or hose connectors on the interior side. With superior corrosion resistance, these fittings ensure a watertight, long-lasting plumbing connection for bilge pump outlets, livewell drains, sink drains, engine cooling water intakes, and more.

• Material: AISI 316 stainless steel – marine-grade anti-corrosion construction
• Sizes: Available with male thread sizes 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2" (standard NPT/BSP as applicable)
• Design: Mushroom head/flange for outer hull, extended threaded shank to accommodate hull thickness and secure with a nut (if provided)
• Use: Thru-hull inlet/outlet for pumps, drains, and plumbing on boats – attach to valves or hoses inside

Plastic boat drain plug with a Ø50 mm drain diameter, equipped with an integrated hasp-type locking mechanism for a secure seal. Made of high-quality UV-resistant polymer that won’t corrode in saltwater. Ideal for installation on the transom or bottom of small to medium boats (including RIBs and jet skis), it allows easy drainage of accumulated water when the boat is on land.

• Ø50 mm opening – a standard drain size for many boats and personal watercraft
• Locking cap design – features a latch mechanism to prevent accidental opening while underway
• Durable plastic construction – non-corrosive, UV-stable, and impact-resistant for long service life
• Easy to use – quick to plug in or remove; locking tab keeps the plug attached so it won’t get lost
• Wide application – suitable as a transom drain plug, for self-bailing cockpit drains, deck drains, and more

A 90-degree plastic hose adaptor designed to securely connect a Ø38 mm hose to tanks or hull fittings at a right angle. Made of white nylon for strength and durability in marine conditions.

• Tough white nylon construction – impact-resistant and non-corrosive in fresh or saltwater
• Connection size: 1¼″ internal threaded inlet and smooth 38 mm hose barb outlet
• 90° elbow design allows installation in tight spaces without kinking the hose
• Ideal for rigid water or fuel tanks – enables convenient angled routing of fluid lines
• Easy to install – screws into tank fitting and secures hose with a clamp for a leak-free connection

Set of 10 wooden conical plugs designed to stop emergency leaks by plugging holes in a boat’s hull or plumbing. The plugs come in assorted diameters (approximately 5 mm up to 45 mm), covering a wide range of hole sizes. When wet, the wooden bungs swell to form an even tighter seal. An essential component of every vessel’s damage control kit.

• 10 wooden plugs in various sizes – seal holes roughly from Ø5 mm to Ø45 mm
• Tapered shape – can be driven into different-sized openings, conforming for a tight fit
• Natural swelling when wet – wood expands upon soaking, increasing the effectiveness of the seal
• Emergency leak stopper – blocks incoming water through broken fittings, burst hoses, or hull breaches
• Easy to use – pick the right-sized plug and hammer it firmly into the leaking hole (or push by hand if necessary)

Oval plastic drain plug with flange base for fixed installation on a boat. Features a 25 mm inner drain diameter and comes in two body length options – short (~27 mm) and long (~67 mm) – to fit different transom or hull thicknesses. A separate spare inner plug (male insert) is included for replacement in case of loss or wear. Made of white ABS material for a watertight seal and durability. Ideal for transom drain points – allows quick draining by removing the plug.

• Oval base with screw holes – easy to mount on transom/deck; low-profile flange sits flush against the hull
• 25 mm inner diameter – standard drain size (can attach to 25 mm hose if needed for draining)
• Two length options: ~27 mm (for thin walls) and ~67 mm (for thick walls) – choose according to your boat’s hull/transom thickness
• Spare plug (code 00923-2) – an additional inner “stopper” insert for replacement; prevents downtime if the original plug is lost
• Secure seal – equipped with a rubber O-ring for watertight closure; ABS plastic is UV-resistant and impact-resistant
