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

Product Introduction

The 2 1/2 inch RTL Type Swab Cup is specifically engineered for the most rigorous wellbore environments where standard cups often fail. Designed with a reinforced, thick-walled lip, the RTL style excels in deep-well swabbing and heavy fluid load recovery. This model is particularly effective in aging wells with pitted, scaled, or rough internal tubing surfaces. By utilizing a high-modulus elastomer compound, the RTL cup provides a durable, positive seal that resists tearing and abrasion, ensuring a longer service life and fewer tool replacements during critical well-servicing operations.

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. Reinforced Lip Profile: The RTL design features a significantly thicker lip than conventional cups, providing the structural strength needed to lift heavy fluid columns without cup inversion or collapse.

2. Rough Tubing Optimization: Specifically formulated to maintain a consistent seal even when traveling through pitted or corroded tubing strings, preventing fluid bypass.

3. Advanced Abrasion Resistance: The industrial-grade NBR material is engineered to withstand the friction of long-distance runs in deep wellbores, maintaining its sealing edge longer than standard cups.

4. High Load Efficiency: The rigid design ensures that the cup stays expanded under maximum hydrostatic pressure, maximizing the volume of fluid recovered in each stroke.

5. Tear and Shred Resistance: The elastomer compound includes specialized additives that prevent shredding when the cup encounters scale or salt buildup on the tubing walls.

Frequently Asked Questions

Question: Can the RTL swab cup be used in new tubing?
Answer: Yes, while it is designed for rough tubing, its heavy-duty construction makes it an excellent choice for any 2.5 inch tubing where a high-volume fluid lift is required.

Question: Does this cup require a specific type of swab mandrel?
Answer: The 2 1/2 inch RTL cup is compatible with standard 2.5 inch high-strength swab mandrels used throughout the oil and gas industry.

Question: How does the RTL handle sand or solids?
Answer: The reinforced lip is much more resistant to the cutting action of sand and solids compared to thinner-lipped cups, making it ideal for post-fracturing cleanouts.

Question: What is the benefit of the NBR material used in this cup?
Answer: The Nitrile (NBR) compound provides the perfect balance of oil resistance and mechanical toughness, which is essential for the friction-heavy environment of rough tubing.
