2.5 Inch RTL Swab Cup with Wear Resistant NBR 80 Durometer and Reinforced Metal Core for Oilfield Well Swabbing

Product Introduction

This 2.5 inch RTL swab cup listing identifies an 80 Shore A NBR version with a reinforced metal core for well-swabbing replacement. Use the nominal size, compound and core reference to begin identification, then confirm the actual cup dimensions and operating configuration. Provide the tubing bore, mandrel details, fluid conditions and planned load before ordering.

Key Features and Benefits

1. RTL Profile Selection: Confirm the cup drawing, lip geometry and metal-core dimensions against the required mandrel and tubing bore. Nominal size does not establish a fluid-load rating.

2. Listed Hardness: The existing specification identifies 80 Shore A NBR. Confirm the compound, hardness tolerance and inspection requirement for the ordered version.

3. Bore Condition: Check tubing restrictions, scale and pitting before selecting the cup. Cup interference and wear condition must suit the actual bore; the RTL name alone does not guarantee sealing in damaged tubing.

4. Wear Inspection: Examine the lip and core interface for cuts, separation and uneven wear. Follow the equipment replacement criteria where abrasion or restrictions are present.

Frequently Asked Questions

Question: Is this cup resistant to oil-based drilling mud?
Answer: Provide the mud base fluid, additives and service temperature. Confirm compatibility for the selected NBR compound; oil-based mud formulations differ.

Question: Can the RTL swab cup be used in new tubing?
Answer: Confirm the actual tubing bore, cup dimensions and load configuration for new tubing. A nominal size reference does not establish fit in every tubing grade or wall thickness.

Question: Does this cup require a specific type of swab mandrel?
Answer: Confirm the sleeve bore, mandrel shoulder, cup height and retention arrangement from the drawing or sample. Nominal 2.5 inch identity alone does not establish mandrel compatibility.

Question: How does the RTL handle sand or solids?
Answer: Confirm suitability for the actual solids concentration and particle size. Monitor wear; no comparative abrasion performance is established by the style name alone.

Question: What is the benefit of the NBR material used in this cup?
Answer: NBR can be evaluated for oil-contact service, with the compound selected for the fluid and wear conditions. Confirm hardness, temperature limits and inspection requirements for the ordered cup.
