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

Product Introduction

The 2.5 inch RTL Swab Cup is a high-performance solution designed specifically for heavy-duty fluid lifting in challenging wellbore conditions. Utilizing an 80 Durometer Nitrile (NBR) compound, this cup provides the structural rigidity necessary to handle large fluid columns while offering the abrasion resistance required for aging or pitted tubing strings. The RTL design focuses on a thick-walled lip profile that maintains a consistent seal against the tubing internal diameter, even under high hydrostatic pressure, making it the preferred choice for deep well production and workover tasks.

Key Features and Benefits

1. High Modulus Design: The RTL geometry incorporates a reinforced lip that resists deflection. This ensures the cup maintains maximum wall contact when lifting heavy loads of brine or crude oil.

2. 80 Shore A Hardness: By utilizing a harder 80 Durometer NBR, this cup reduces the risk of extrusion into the tubing gaps, providing a longer service life in deep-hole applications where heat and pressure are factors.

3. Rough Tubing Adaptability: Engineered specifically for wellbores with scale buildup or pitting, the RTL lip provides enough interference to seal gaps that would cause lighter SV or V type cups to bypass fluid.

4. Exceptional Mechanical Shear Resistance: The proprietary NBR blend is treated to resist tearing and shearing when passing through salt bridges or localized tubing restrictions.

Frequently Asked Questions

Question: Is this cup resistant to oil-based drilling mud?
Answer: Yes, the high-grade Nitrile material is specifically formulated for compatibility with oil-based fluids, diesel, and crude oil.

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.
