Eaton Replacement Model 50 Parts

(0 products)

Eaton pipeline strainers are known for their purposeful design and premium quality. There are knock-off strainers and there are knock-off parts. At CIS, we don't sell any of those. We deal strictly with authentic Eaton brand filtration products, like this model 50 duplex strainer. When it comes to removing matter from your liquid media, you can't afford any downtime. Duplex strainers help minimize downtime by allowing diversion of flow from one filtration chamber to another. Another way to minimize downtime is to keep spare parts of the most critical and easily damaged or misplaced parts. Commercial Industrial Supply is the go-to source for replacement parts for Eaton filtration users around the world.
