High Performance Swabbing 2-7/8" Steel Core Oilfield Oil States Swab Cups
2-7/8-inch Steel-Core TA Swab Cups: Replacement Dimensions and Mandrel Fit
For a 2-7/8-inch steel-core replacement, compare the existing cup drawing with the TA cup profile and the mandrel dimensions. The original catalog lists the 2-7/8-inch steel-core cup at 2.431-inch OD and 1.370-inch ID; tubing reference size is not the cup diameter. Confirm cup height and bushing fit before ordering. The specified steel bushing must match the specified profile and mandrel. Send the worn-cup reference or drawing, tubing bore, fluid composition, solids content and operating temperature to select a suitable replacement compound.
