Swab Cup Selection: Tubing Fit, Core Bore and Operating Duty
Royal Way supplies rubber swab cups for equipment-defined oilfield swabbing operations. Select the cup profile, outside diameter and bushing bore for the tubing and mandrel. NBR or FKM compound enquiries require review of the actual fluid and temperatures; the cup alone has no independent 10,000 psi working-pressure rating.
The existing range introduces TA, V and other swab cup profiles with different load and support arrangements. Select the exact design for the tool and operating conditions. Do not infer interchangeability or lifting capacity from a general heavy-duty description.
Existing nominal tubing references include 2 3/8, 2 7/8, 3 1/2 and 4 1/2 inches. Confirm tubing inside diameter, drift condition, cup outside diameter and mandrel fit before ordering. The table below retains the original catalogue dimensions; verify the selected row against the approved tool drawing.
Swab Cup Dimensions: Separate Tubing Reference, Cup OD and Core Bore
Choose the nominal tubing row first, then confirm the actual cup OD and mandrel bore. In the retained table, a 2-7/8-inch tubing reference is paired with a 2.431-inch cup OD and a 1.370-inch cup ID; these are different measurements. Do not use the tubing OD as the rubber cup diameter.
Provide the tool drawing, tubing inside diameter, core material, cup height and compound grade with the order. Confirm fluid composition, temperatures, sand conditions and permitted tool duty. Specify the selected catalogue dimensions and required tolerances on the approved cup drawing.

Replacement cup enquiries can be discussed from the required profile and approved drawing. Specify the nitrile or other compound grade and actual fluid exposure. Profile references do not imply original-brand manufacture or universal compatibility.
Available types of Swab cups:
TA style
TA is described in the existing range as a medium-load cup around a steel or aluminum bushing. Confirm the particular core material, cup profile and mandrel bore for the selected size. Load suitability and compound performance depend on the approved tool configuration and operating conditions.
V style:
The existing V-series description covers all-rubber lip profiles for sand-bearing fluid enquiries. Cup count, lip behaviour and load limits must follow the tool maker’s instructions. Review the selected compound for fluid, temperature and wear conditions rather than assigning universal chemical resistance.
TUF style:
The TUF-style description refers to an internally reinforced cup profile. Confirm the reinforcement, dimensions and load requirements against the tool drawing. Hot-well or rough-tubing suitability requires review of the actual compound and tubing condition.
NUF style:
The NUF-style description refers to a heavy-load rubber cup with a steel or aluminum bushing arrangement. Specify the exact profile, core material, dimensions and approved tool duty. A heavy-load description does not establish a pressure or lifting-capacity rating.
