The Groco ARG-1500-S is a bronze strainer with 1-1/2 inch NPT ports and a stainless basket, standing 10-3/4 inches tall. There are no tie rods or gaskets, and O-rings seal the mating surfaces. The basket has 0.077 inch holes and 45% open area. A screw-on retainer cap allows servicing without tools, and a strap mounting system lets the whole strainer come off without tools.
Our take
The ARG-1500-S has no tie rods or gaskets and seals with O-rings behind a screw-on cap, so servicing the basket takes no tools. Its basket is stainless, not the monel option the maker recommends for saltwater use.
From our buying guide
Makers disagree on where to mount a strainer: Groco's installation sheet recommends above the waterline, and Westerbeke's generator manual says at or below it. Perko says to consult the engine manual for pipe size and strainer location.
Check before you buy:
- It matches your pipe size, since Perko says reducers may cause engine damage and are not recommended.
- You can reach the basket, since Groco says to inspect and clean it frequently.
- Open-area figures are compared within one maker, since each states its own measure.
