Stainless Steel 316 Thru-Hull with Hose Barb – Sizes 3/8" to 1"

Code:
00819-7

Premium AISI 316 stainless steel thru-hull fittings featuring an integrated hose barb (tailpiece) for direct hose connection. Available in common hose sizes 3/8", 1/2", 3/4", and 1", these thru-hulls allow you to run a hose straight to the fitting without needing a separate adapter. Each fitting has a wide flange for the hull exterior and a barb on the interior side to securely clamp your hose. They are ideal for above-waterline drains (scuppers, sink drains, livewell overflow) or any application where a hose needs to pass through a bulkhead or hull with a secure, leak-free connection. Manufactured from marine-grade 316 stainless, they offer superior strength and corrosion resistance compared to plastic fittings.

  • Material: AISI 316 stainless steel, one-piece body with barb – rustproof and strong
  • Hose Sizes: Comes in 3/8", 1/2", 3/4", 1" barb diameters to fit standard hoses
  • Design: Mushroom head outer flange and ribbed hose tail interior for hose clamping
  • Application: Direct hose connections for bilge pump discharge, sink or shower drains, livewell/baitwell connections, fuel tank vents (check size), etc.

Simplify your plumbing setup with these integrated barb thru-hull fittings, which eliminate extra connections and potential leak points. Each fitting is a one-piece unit: the outer part has a smooth flange that mounts flush to the hull or tank wall, and the inner part is a ribbed hose barb sized to fit your hose snugly. For installation, you will apply a marine-grade sealant under the outer flange and insert the fitting through the hull from the outside. A nut (usually included, also stainless) threads onto the backside to clamp it tight. On the inside, just slide your hose (of matching size) onto the barb and secure it with one or two stainless hose clamps. The barb’s ridges ensure the hose won’t slip off under pressure. Using 316 stainless steel means these thru-hulls can be used for both freshwater and saltwater systems, and even for certain chemical or fuel vent applications (given the material’s compatibility and non-sparking quality). Typical uses on a boat: connect your bilge pump’s discharge hose to a 3/4" or 1" barb thru-hull that exits above waterline; route a sink drain through a 1/2" or 3/4" barb fitting out the side of the hull; use a 3/8" or 1/2" barb fitting for a shower drain or air conditioner condensate drain; or install a 5/8" (usually using 1/2" NPT or similar barb) as a fuel tank vent outlet (often located on the topsides). The advantages over plastic: these metal fittings won’t break if stepped on or hit, can handle higher temperatures, and won’t embrittle over time. Plus, the polished stainless exterior looks far superior on your hull – a small detail that complements other stainless hardware. Ensure to select the correct hose ID (inner diameter) to match the barb. Also note that while these fittings are generally used above the waterline (since they don’t incorporate a seacock), they can be used below waterline ONLY if paired with an internal seacock/valve for safety, or if used as a vent. Maintenance is minimal: occasionally check the hose clamp for tightness and inspect the exterior flange for seal integrity. These stainless barb thru-hulls will provide a secure, straightforward solution for moving water in and out of your boat’s systems, and thanks to their 316 construction, will do so trouble-free for years.
