Steel-Core Swab Cup Maintenance: Wear Conditions and Replacement Fit
Royal Way supplies steel-core swab cup enquiries for downhole fluid lifting. Review the rubber compound and cup profile for the tubing condition, sand exposure and operating fluid. Confirm core dimensions and mandrel fit separately. A cup has no independent 10,000 psi working-pressure rating.
The existing catalogue introduces TA, V and MV profile references with different support and lip arrangements. Confirm the exact steel-core design and permitted tool duty. A steel core does not establish universal load, temperature or pressure capability.
Nominal tubing references include 2 3/8, 2 7/8, 3 1/2 and 4 1/2 inches. Match cup OD and core bore to the tubing inside diameter and mandrel drawing. Custom enquiries require agreed dimensions, compound, hardness and inspection criteria.
Steel-Core Swab Cup Wear Review: Record Tubing and Sand Conditions
For a replacement enquiry following wear, provide photographs of the lip and core seating area together with the approved new-part drawing. Include tubing inside diameter and condition, sand concentration if known, fluid composition and temperatures. Wear resistance depends on the compound and operating contact, not the steel core alone.
Do not use a worn or swollen cup as the sole dimensional reference. Confirm the original cup profile, core bore and height, mandrel arrangement and rubber grade. Follow the tool maker’s inspection criteria before reuse or replacement.

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.
