It features a 6 5/8” x 6 5/8” size, compatible with standard drill strings, and is made of high-strength alloy steel that withstands tensile loads up to 500 tons—matching the continuous torque capacity of TDS-11SA top drives (37,500 ft-lb @ 125 rpm). The precision-threaded design ensures a secure connection, preventing thread stripping and drill string separation. It has a service life of 15,000 operating hours—4,200 hours longer than generic saver subs—and is resistant to corrosion from drilling mud and H2S exposure (compliant with GB 46995-2025 standards for H2S environments).
IBOP H2S Trim (P/N 114706-502 Lower & 110103-502 Upper)
These H2S trim components address the pain point of IBOP failure in sour gas wells, where H2S corrosion causes seal degradation and well control risks. The lower IBOP H2S trim (P/N 114706-502) and upper IBOP H2S trim (P/N 110103-502) are designed for 6 5/8” x 6 5/8” IBOP units, rated for 15,000 PSI working pressure. They feature corrosion-resistant materials (Inconel alloy) that withstand H2S concentrations up to 20,000 mg/m³, meeting GB 46995-2025 safety requirements for H2S environments. The trim includes specialized seals and valve seats that prevent H2S ingress, extending IBOP service life by 6,000 hours and eliminating corrosion-related failures.
Hydraulic Pump (P/N 107783-5C11R)
This vane hydraulic pump solves the pain point of hydraulic system pressure loss and inefficiency in TDS-11SA top drives, which causes slow actuation of IBOPs and hydraulic cylinders. It delivers a flow rate of 18 GPM at 3,000 PSI, ensuring consistent hydraulic pressure for smooth operation of IBOP cylinders, link tilt cylinders, and other hydraulic components. The pump features a durable vane design that reduces wear, with a service life of 9,000 operating hours—2,800 hours longer than standard hydraulic pumps. It is compatible with all TDS-11SA hydraulic systems and includes a built-in pressure relief valve to prevent overpressure damage.
SEAL KIT (P/N 87605-1 & 109528-2)
Our seal kits address the pain point of hydraulic leakage, which wastes hydraulic fluid, reduces system efficiency, and causes equipment damage. The SEAL KIT (P/N 87605-1) is designed for IBOP cylinders, while P/N 109528-2 is tailored for TDS-11SA top drive components. Each kit includes high-temperature, H2S-resistant seals (fluorocarbon rubber) that withstand temperatures up to 180°C and pressures up to 15,000 PSI. The kits include all necessary seals, gaskets, and O-rings for a complete repair, reducing maintenance time by 4 hours per repair compared to sourcing individual seals. Each seal in the kit has a service life of 5,500 operating hours—1,300 hours longer than generic seals.

Maintenance & Operation Tips
To maximize the service life of our spare parts and ensure optimal performance of TDS-11SA/TDS-11A top drives and IBOP systems, our senior drilling equipment engineers—with 19+ years of on-site experience—recommend the following practical tips:
• SAVER SUB 76666-2: Inspect the threads every 30 days for wear or damage; apply high-pressure thread compound before installation to prevent thread stripping. Avoid over-torquing—use a torque wrench set to 1,200 ft-lb to ensure a secure connection without damage.
• IBOP H2S Trim (114706-502, 110103-502): Inspect the seals every 6 months for H2S-induced corrosion; replace the trim every 12,000 operating hours or immediately if corrosion is detected. Store spare trim in a dry, sealed container to prevent H2S exposure before installation.
• Hydraulic Pump 107783-5C11R: Change the hydraulic fluid every 2,000 operating hours; clean the inlet filter monthly to prevent debris from damaging the pump vanes. If the pump makes unusual noise, check for low fluid levels or air ingress—these issues can reduce service life by 50%.
• SEAL KIT 87605-1/109528-2: When installing seals, use a plastic tool to avoid damaging the seal lip; apply hydraulic grease to the seal before installation to reduce friction. Replace all seals in the kit at once—mixing old and new seals can cause leakage.
• General tip: Keep critical spare parts (especially IBOP H2S trim, hydraulic pumps, and seal kits) on-site to minimize downtime during emergencies. Label each part with its model number and applicable equipment to ensure quick identification. Follow API 6A and GB 46995-2025 guidelines for maintenance in H2S environments.
Engineer’s warning: Never use non-API 6A or non-GB 46995-2025 compliant spare parts in H2S environments or TDS-11SA/TDS-11A top drives—this can cause equipment failure, well control risks, and void your equipment’s warranty. Our parts are 100% compatible with the specified equipment, and we provide technical support to help you select the right part for your specific model.
