Polish your image with these beautiful, durable stainless steel fittings. Each Thru-Hull and Scupper Valve is backed by Attwood's trusted Lifetime Warranty! Why specify plastic parts when these fittings will last the life of the boat? This product does not include a gasket.

Rugged Stainless Construction

  • Cast from certified enhanced #316 Stainless Steel allow for strength and lifetime corrosion-resistance
  • We polish all visible areas to a mirror finish, then each part through a passivation for additional protection
  • Thick steel sidewalls withstand continual stress and hose flexing

Faster, Simpler Installation

  • A channel under the flange holds a bead of sealant, making it easier to apply a trouble-free seal
  • All models have wrench flats or an end notch to hold as a gripping surface. One installer can tighten all connections from inside the hull
  • Barbed tail ends provide plenty of room to hold multiple clamps

Caution: Thru-Hull connectors are designed for installation above the water line only.

About Me Professional

Comments about Attwood Stainless Steel Straight Thru-hull Barbed, Standard Length, 1 1/2":

This is actually a joke. This thru-hull does not come with a gasket at all. The good folks at Newport Beach West Marine assured me that this is a misprint and there is no gasket. They called the Sarasota Fl store, who confirmed there are no gaskets in any of these thru-hull packages. I ended up paying more for this product than the on the shelf thru-hull that they had at the store....and I had to wait days to have it shipped into the store (costumers do not like to wait when you are installing a thru-hull for their generator that they need for Labor day). Bottom line, just by the less expensive one and glue it in and deal with the mess.
