2 1/2 Inch RTL Heavy Load Swab Cup with Reinforced Thick Lip for Deep Wellbore Services

Product Introduction

This 2-1/2 inch RTL swab cup listing covers a rubber-and-metal replacement configuration for well service. The existing specification lists NBR with an 80-90 Shore A range. Confirm the required grade, profile and mandrel dimensions for the order; hardness alone does not establish load capacity. For deep-well maintenance, include the fluid, temperature, bore condition and observed wear with the replacement request.

Technical Specifications

	Material:	High-Abrasion Nitrile (NBR)
	Size:	2 1/2 Inch
	Style:	RTL
	Hardness:	80 to 90 Shore A

Key Features and Benefits

1. Profile Identification: Confirm the lip thickness, cup dimensions and core configuration from a drawing or unworn sample. The RTL designation alone does not confirm a heavy-load rating.

2. Tubing Condition: Record scale, corrosion, pitting and restrictions when requesting a replacement. Confirm the cup fit for the actual tubing internal diameter.

3. Wear Review: Provide photographs of the worn sealing edge and service history. Confirm the compound and operating conditions rather than inferring comparative life from the material name.

4. Load Configuration: Specify the planned fluid load, mandrel and cup arrangement. The pressure and lifting capability of the complete assembly require equipment-specific confirmation.

5. Damage Inspection: Inspect for tearing, loose rubber and separation at the core. Follow the equipment replacement procedure where scale or restrictions are present.

Frequently Asked Questions

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.
