Fluid Ends

The Original L-Shaped Fluid-End

Often imitated but never duplicated, Southwest Oilfield Products’ two-piece L-shaped fluid-ends have become the recognized standard. L shaped fuild end orange

The L-shaped two-piece fluid-end was adopted into the market over 35 years ago because it was an obvious improvement over one-piece modules. Since the suction module is separate from the discharge module, it is possible to replace the suction module when it wears out instead of replacing the entire fluid end.

Changing valves or seats on a two-piece module is also much easier, safer, and faster than changing valves or seats on a one-piece module.

Southwest’s L-shaped fluid-end is manufactured from heat-treated 4130 forgings and equipped with our quick-change valve cover system; our L-shaped modules offer unmatched performance.

Southwest’s second to none manufacturing is backed by the best warranty on the market.
