The Perko 493 Series strainer in the 1/2 inch pipe size is made for easy installation and cleaning. It has a cast bronze cover on hinged lugs, mounting lugs cast into both sides, and a 304 stainless steel basket. The basket screen has 0.077 inch holes and is 46% open. A drain plug in the bottom casting lets you remove sediment.
Our take
The drain plug in the bottom casting lets you clear sediment without pulling the basket, and the hinged bronze cover makes the basket itself easy to remove. Perko points anyone who needs higher flow rates to its 500 Series instead.
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.
