Polish your image with these beautiful, durable stainless steel fittings. Each Thru-Hull and Scupper Valve is available with a new silicone gasket and are backed by Attwood's trusted Lifetime Warranty! Why specify plastic parts when these fittings will last the life of the boat? 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. A channel under the flange holds a bead of sealant, making it easier to install and 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.
