The GROCO ARG-755-P Raw Water Strainer is a compact 3/4" NPT filtration system designed for smaller marine engines, generators, and air conditioning units. The "-P" designation signifies it is equipped with a non-metallic polyethylene basket, making it the ideal choice for systems that run continuously.

Optimized for Continuous Use

While metal baskets are durable, they can eventually suffer from electrolysis or pitting when water flows through them 24/7.

• Corrosion-Proof Basket: The polyethylene basket is entirely immune to electrolysis, ensuring it will never corrode or bind to the housing, regardless of water salinity.

• Space-Saving Design: This is the "short" version of the ARG series, standing only 6.125 inches tall, which is perfect for tight engine rooms or under-sole installations.

• Tie-Rod-Free Construction: By eliminating traditional rods and gaskets, GROCO has removed the most common leak points found in older strainer designs.

• Maintenance Without Tools: The spin-off wingnut cap and quick-release mounting strap allow you to clear the basket or service the unit in seconds without a wrench.

Summary Recommendation

The ARG-755-P is the superior option for air conditioning and refrigeration systems where the pump may run for weeks at a time. For standard engine cooling in extreme saltwater, you might consider the Monel basket version for added structural rigidity.
