GROCO 93-1250-03 Stainless Steel Replacement Screen f/APHS-1250 - Size 3 (.188") Perforation Diameter

The GROCO 93-1250-03 Stainless Steel Replacement Screen for APHS-1250 is a precision intake strainer component engineered for marine and fluid-handling systems that demand reliable particulate filtration. This Size 3 replacement screen features a .188-inch perforation diameter, making it the correct mesh specification for the APHS-1250 seawater strainer assembly. Built from stainless steel, it resists corrosion in saltwater environments where standard steel screens fail rapidly, protecting engine cooling systems and raw-water circuits from sand, debris, and other contaminants.

The .188-inch perforation diameter is the critical specification for this model—it balances flow rate with effective particle exclusion, preventing blockages that can overheat inboard engines or damage raw-water pumps. The compact 3 x 3 inch dimensions fit directly into the APHS-1250 strainer housing without modification. Stainless steel construction (typically 316-grade in GROCO marine applications) provides decades of service life even in harsh coastal or offshore environments where salt spray accelerates corrosion of inferior materials.

This replacement screen is essential maintenance for boat owners relying on through-hull cooling systems. Whether running a fishing vessel on saltwater patrol, cruising long-range offshore, or maintaining a weekend recreational boat, a clogged or corroded strainer screen reduces water flow and forces engines to work harder, raising operating temperatures and fuel consumption. Keeping a spare GROCO 93-1250-03 screen on board ensures fast, reliable repairs without the downtime of waiting for parts or dealer service calls.
