      Marine Thru Hull Fittings and Strainers

      Scoop strainers are designed to prevent debris from entering and clogging your cooling system, while marine thru hull fittings connect plumbing or fuel hoses from the interior to the exterior. These may not be expensive boat parts, but they are very important. That’s because marine thru hull fittings/strainers ensure that water does not breach your boat’s infrastructure. Many a craft has been scuttled for lack of a water-tight fitting, so be sure to maintain your boat’s fittings and strainers with reliable replacement parts from Wholesale Marine.

      Wholesale Marine carries marine thru hull fittings and strainers by Attwood, Garmin, Groco, Johnson Pump, Shurflo, T&H Marine, and Whale Marine. For years of efficient service, we recommend Groco’s Tri-Flanged Ball-Type Seacock. It features a patented field reversible handle with a choice of closed position options, and will accept standard ratchets.
