All products adhere to authoritative industry standards, including API 6A (for wellhead and drilling equipment), ISO 9001:2015 (quality management), GB/T894.1-1986 (for stop rings), and ANSI/API Spec 6A for critical drilling components. Exclusive third-party test data validates performance: our Hydraulic Oil Filter 30173216-1 Varco TDS-11SA filters particles as small as 5 microns, maintaining oil cleanliness for 2,500 operating hours; the Desilter Cyclone Nozzle 10523-02 maintains a stable flow rate of 18 GPM at 150 PSI, ensuring consistent desilting performance; and the Bushing BKD-3-6C reduces friction coefficient to 0.08, extending brake system life by 3,000 hours. Backed by over 20 years of experience supplying drilling and hydraulic parts, each component undergoes rigorous material testing, dimensional verification, and field simulation—ensuring seamless compatibility with equipment models like Varco TDS-11SA, PS series hydraulic disc brakes, and ZQ-203-125 hydraulic tongs. Our parts are engineered to solve real-world problems, from preventing hydraulic oil contamination to maintaining precise desilting, and we stand behind every product with industry-leading quality assurance.

Product Overview

Core Product Models & Functions

Our lineup focuses on mission-critical components that solve specific operational challenges across drilling, hydraulic, and mud treatment systems, with each part designed to address common pain points:
- Hydraulic Oil Filter 30173216-1 Varco TDS-11SA: Specifically designed for Varco TDS-11SA top drive systems, it filters out contaminants (down to 5 microns) from hydraulic oil, solving the problem of oil contamination that causes valve jamming and pump wear. This filter ensures hydraulic system stability, reducing unplanned downtime by preventing component failure.
- Desilter Cyclone Nozzle (0,625-0,500) 10523-02: A key part of mud desilter systems, it maintains consistent flow and pressure to separate fine solids (0.500-0.625 mm) from drilling mud, eliminating the pain of reduced desilting efficiency and mud waste. It ensures drilling fluid meets required specifications, protecting downhole tools.
- Bushing BKD-3-6C: For PS series BKD-3-6C hydraulic disc brakes, it reduces friction between moving parts, solving the issue of brake drag and premature wear. It ensures smooth brake operation, critical for drilling rig safety.
- 3-WAY SWITCH, BARTEC 123075-21-41: A dual-location control switch for drilling equipment, allowing operators to control systems from two separate locations—solving the inefficiency of single-location controls and improving operational safety.
- Jaw Support Insert FP-11-02-0097: A spare part for ZQ-203-125 hydraulic tongs, it prevents jaw slippage during pipe makeup/breakout, avoiding pipe damage and safety risks.

Maintenance and Care Suggestions

Our engineering team, with 15+ years of hands-on oilfield maintenance experience, shares practical tips to extend component life and avoid common mistakes—tips we’ve learned from working directly with drilling teams:

• Hydraulic Oil Filter 30173216-1 Varco TDS-11SA: Replace every 2,500 operating hours or if pressure drop exceeds 25 PSI. Always flush the hydraulic system before installing a new filter to remove residual contaminants. Pitfall Reminder: Do not reuse filters—this reintroduces contaminants and causes hydraulic component failure.

• Desilter Cyclone Nozzle 10523-02: Inspect every 800 hours for wear; replace if inner diameter wear exceeds 0.01 inches. Clean the nozzle with a soft brush (not abrasive cleaners) to remove mud buildup. Pitfall Reminder: Do not overtighten the nozzle—this damages the threads and causes leaks.

• Bushing BKD-3-6C: Apply high-temperature lithium grease (NLGI Grade 2) every 300 hours. Check for play or wear every 500 hours; replace if movement exceeds 0.002 inches. Pitfall Reminder: Do not install a bushing with burrs—this causes uneven wear and brake drag.

• 3-WAY SWITCH, BARTEC 123075-21-41: Keep the switch clean and free from mud/debris; wipe with a dry cloth every 100 hours. Avoid using excessive force when toggling the switch—this damages the internal contacts. Pitfall Reminder: Do not expose the switch to direct water spray—even with IP67 rating, prolonged exposure can cause internal damage.
