GROCO Bronze Clam Shell Style Hull Strainer w/Mount Ring f/Up To 1" Thru Hull

The GROCO Bronze Clam Shell Style Hull Strainer with Mount Ring for up to 1" through-hull fittings is an essential intake protection component for any serious saltwater or freshwater boater. This strainer sits inline with your raw water cooling system, engine intake, or livewell circulation, preventing seaweed, debris, and sediment from clogging critical seacock lines.

Built from durable bronze, the GROCO clam shell design features a hinged, easy-access basket that allows rapid inspection and cleaning without breaking the through-hull connection. The bronze construction resists corrosion in saltwater environments and won't degrade or weaken over years of exposure to harsh marine conditions. The included mount ring adapts securely to 1" nominal through-hull penetrations, and the compact profile fits tight engine compartments without requiring major plumbing modifications.

Every captain running a raw water cooling loop, head system, or livewell pump should carry a backup strainer basket and inspect the main unit at least once per season. Installation is straightforward on vessels equipped with 1" through-hull fittings—most installations take under an hour. The mechanical straining basket captures larger debris while allowing clean water flow to maintain proper system pressure and temperature.
