Stellar Industries 86123 Zinga SMF-12 SAE Tank-Top Hydraulic Filter Assembly

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar Industries 86123 Tank-Top Filter is a complete Zinga SMF-series hydraulic return-filter assembly designed for compatible Stellar reservoirs. It features size-12 SAE connections, an internal replaceable filter element, and an integrated bypass valve.

Mounted directly to the reservoir, the filter removes damaging contaminants from returning hydraulic oil before it reenters the tank. Replacing a damaged or restricted assembly helps maintain proper return flow and protects pumps, valves, cylinders, and motors from contaminated fluid.

What This Part Is Used For
