Groco RSC-4000 Bronze Round Hull Strainer with Access Door for 4" Thru-Hull

The Groco RSC-4000 is a heavy-duty bronze round hull strainer designed to protect marine plumbing systems and equipment from debris entering through thru-hull fittings up to 4 inches in diameter. Constructed from corrosion-resistant C84400 bronze, this strainer is built to withstand harsh saltwater environments while providing reliable filtration for raw water intake systems.

Key Features:

• Patented access door design provides convenient access to thru-hull fittings for inspection and maintenance without removing the entire strainer
• Premium C84400 bronze construction on both body and access door for superior corrosion resistance
• Cast filter holes machined directly into the bronze body for durability and consistent filtration
• Passive flow design ideal for gravity-fed systems or applications where forced flow is not required
• Accommodates thru-hull fittings up to 4 inches in diameter
• Round configuration provides efficient water flow and debris collection

This strainer is ideal for protecting marine engines, pumps, air conditioning systems, and other onboard equipment that rely on raw water intake. The access door feature significantly reduces maintenance time and effort compared to traditional hull strainer designs, making it a practical choice for both professional and recreational vessel operators.
