GROCO BM-8 Monel Basket - 3.1" x 12.4"

The GROCO BM-8 Monel Basket is a replacement raw water strainer basket engineered for marine and offshore applications requiring corrosion resistance in salt air and harsh saltwater environments. Constructed from high-strength Monel—a nickel-copper alloy prized for its superior resistance to seawater corrosion—this 3.1" diameter by 12.4" length basket delivers reliable sediment and debris filtration for through-hull intake systems on vessels and marine equipment.

Monel's inherent resistance to galvanic corrosion and stress-corrosion cracking makes it the preferred material for raw water strainer baskets in marine duty, where standard stainless steel and mild steel alternatives fail prematurely. The basket features an improved handle design for easier installation and removal during routine maintenance cycles. Its compact 3.1-inch diameter allows it to fit a range of standard through-hull strainer housings, while the 12.4-inch length accommodates typical marine plumbing configurations without requiring extensive system modifications.

This replacement basket is engineered as a direct-fit component for GROCO ARG-2000 and SA-2000 raw water strainer housings—common fixtures on cruising sailboats, trawlers, commercial fishing vessels, and marine engines requiring continuous raw water cooling. Regular basket replacement maintains strainer efficiency and prevents pump cavitation caused by blocked intake flow. The BM-8 is specified when upgrading from original equipment or restoring legacy marine systems where corrosion-resistant components are non-negotiable for extended service life in saltwater duty.
