MERIT High-Temperature Foam Wiper Balls for 2 3/8″ and 2 7/8″ Stingers – Engineered Excellence for Oilfield Operations

Constructed from premium natural rubber with an open-cell foam matrix, MERIT’s foam wiper balls are built to withstand temperatures ranging from 40°F (4°C) to 302°F (150°C). This exceptional thermal resilience makes them ideal for high-pressure, high-temperature (HPHT) environments commonly encountered in deep well drilling and stinger operations. Whether you’re dealing with oil-based muds, water-based fluids, or cement slurries, our wiper balls maintain structural integrity and wiping efficiency, ensuring reliable performance where lesser materials falter.

Precision Fit for 2 3/8″ and 2 7/8″ Stingers

Our foam wiper balls are meticulously sized to provide a snug, effective fit within 2 3/8″ (2.375″ OD) and 2 7/8″ (2.875″ OD) stingers, with internal diameters typically ranging from approximately 1.995″ to 2.441″. Featuring a parting stretch of 380% to 440%, these balls compress and expand to navigate tight restrictions—such as mechanical tools, diverters, or tapered strings—without compromising their cleaning capability. This elasticity ensures seamless passage through the stinger’s ID while delivering a thorough wipe of cement, drilling fluids, and debris.

Engineered for Oilfield Efficiency

In oilfield applications, maintaining clean stingers and drill pipes is critical to operational success. MERIT’s foam wiper balls excel at:

• Debris Removal: Effectively clear residual mud, cement, and cuttings to prevent blockages and maintain fluid circulation.
• Fluid Separation: Isolate incompatible fluids (e.g., mud and cement slurry) to enhance zonal isolation and well integrity.
• Durability: Resist degradation in abrasive and chemically aggressive environments, reducing downtime and replacement costs.

Backed by over 15 years of field-proven success since 2005, our wiper balls have been deployed in oilfields worldwide—from the Permian Basin to the North Sea—delivering consistent results in both onshore and offshore operations.
