GROCO PWSA-1251 Poly Basket Fits WSA-1250 & WSB-1250

The GROCO PWSA-1251 Poly Basket is a replacement strainer basket designed to fit the GROCO WSA-1250 and WSB-1250 series seawater strainers. This compact poly basket serves as the primary filtering element in marine through-hull seawater intake systems, trapping debris and sediment before water enters engine cooling circuits or other onboard systems.

Measuring 5 × 4 × 7 inches and weighing only 0.15 lbs, the PWSA-1251 basket is engineered from marine-grade polycarbonate plastic to withstand saltwater corrosion and UV exposure. The poly construction resists rust and degradation common to metal strainer baskets in harsh marine environments, extending service life while reducing maintenance. The basket's open-mesh design maximizes flow rate while effectively screening particles that would otherwise damage impellers, heat exchangers, or raw-water cooling systems.

This basket replacement is essential for vessel operators, marine mechanics, and yacht maintenance professionals who rely on GROCO strainer systems. Regular basket replacement prevents system blockage, maintains consistent cooling-water flow, and protects critical engine components. The WSA-1250 and WSB-1250 strainers are standard on many cruising sailboats, fishing vessels, and commercial marine installations where dependable seawater intake filtration is non-negotiable.

GROCO strainers are recognized marine industry standards for raw-water intake systems. Keeping spare baskets on hand ensures no downtime during offshore passages or remote anchorages where replacement parts may be unavailable. The PWSA-1251 is the correct OEM-equivalent basket for your compatible GROCO strainer model.
