Function & Pain Point Solutions

Every accessory we supply is designed to solve the real-world problems oilfield professionals face daily—problems we’ve witnessed firsthand through decades of working alongside drilling and maintenance teams. Here’s how our key products deliver tangible value:

• Sealing & Dustproof Components (KHT7625-582 As568 O-Ring 29.75×2.75, KHT7625-860 GB/T10708.3 Dustproof Ring): Stop hydraulic fluid leaks and dust intrusion that damage equipment. Our As568 O-ring (29.75×2.75) complies with the American AS568 standard, made of high-temperature fluorine rubber that withstands -45℃ to 200℃ operating temperature and 35MPa pressure, solving the problem of leaky seals that cause hydraulic system failures. The GB/T10708.3 dustproof ring (25x140x9.5) keeps dust, sand, and debris out of moving parts, extending component life by 1,800 working hours.

• Instrumentation & Hydraulic Parts (KHT7625-603 Pressure gauge Y-60ZT, KHT7625-589 Hose): Eliminate inaccurate pressure readings and hose failures. Our Y-60ZT pressure gauge (0-3600PSI) has a 1.5 accuracy grade, operates reliably in -40℃ to 70℃ environments, and provides precise pressure monitoring for XQ89/3YC power pliers—avoiding costly mistakes from incorrect pressure readings. The 10II-1600 hose (3/4-16UNF, flared ends) is designed to handle high pressure, resisting kinking and leakage for 2,100 working hours.

• Transmission & Positioning Parts (KHT7625-429 Locating shaft sleeve, XYQ6B pliers block pin 6B.Z-38): Prevent component misalignment and jamming. Our locating shaft sleeve ensures precise positioning of transmission parts, reducing wear and avoiding gear jams under 34,000 N·m torque. The XYQ6B pliers block pin (6B.Z-38) is made of high-strength steel, lasting 2,200 working hours without bending or breaking—solving the problem of pin failure that halts pliers operation.

• Jaw & Clamping Parts (800 520-S-160 Lug Jaw Assembly, KHT7625-802 Front Jaw set 4 1/2″): Solve slipping jaws that damage pipe threads and reduce clamping force. Our lug jaw assembly and front jaw sets are made of wear-resistant alloy, maintaining a secure grip even after 4,100 make-up/break-out cycles, and are precision-machined to fit 800 520-S-160 and KHT8625 models perfectly—complying with API 7K standards for casing and tubing operations.

Structural Features

Our accessories are built to withstand the harshest oilfield conditions—from dusty onshore rigs to corrosive offshore platforms—with a focus on durability, ease of use, and long service life:

• Material Excellence: Transmission parts (shaft sleeves, pins, bearings) use high-strength alloy steel, while sealing components use fluorine rubber and nitrile rubber to resist oil, high temperatures, and corrosion (complying with AS568 standards for O-rings). Fasteners like KHT7625-356 Bolt and KHT7625-511 Hex bolt are made of high-carbon steel, ensuring high tensile strength and fatigue resistance for 13,500+ assembly cycles. The deep groove ball bearing 307 uses high-quality bearing steel, with a smooth surface finish to reduce friction.

• Precision Manufacturing: All parts are processed with CNC machining, ensuring dimensional accuracy within ±0.007mm—critical for components like KHT7625-429 Locating shaft sleeve and XYQ6B pliers block pin 6B.Z-38 that require a perfect fit to avoid equipment jams. This precision matches the original equipment’s specifications, eliminating the need for modification during installation, and aligns with API 7K and SY/T 5074-2012 manufacturing standards.

• User-Centric Design: Key parts like KHT7625-732 RHF-2 Valve core and KHT5500-240 Connector element are designed for easy installation and maintenance, allowing technicians to replace parts in minutes rather than hours. The 01.08.00M Hydraulic & pneumatic control features intuitive operation, reducing human error and ensuring precise control of XQ89/3YC power pliers. Grease cups (KHT5500-20, KHT7625-84) are easy to refill, simplifying lubrication maintenance.

Applicable Working Conditions

Our accessories are engineered to perform reliably in the most challenging oilfield environments, meeting the demands of onshore, offshore, and high-torque drilling scenarios—complying with API 7K and SY/T 5074-2012 standards for drilling and workover power tongs:

• Onshore Oilfields: Adapt to extreme temperature ranges of -55℃ to 110℃, resisting dust, sand, and heavy vibration during drilling and workover operations. Ideal for arid regions like Turpan-Hami and Daqing, where dust and temperature fluctuations can damage low-quality parts. Our pressure gauges and hoses perform reliably even in these harsh conditions, maintaining accuracy and integrity.

• Offshore Oilfields: Corrosion-resistant materials (including stainless steel fasteners and fluorine rubber seals) prevent damage from saltwater and humid air, ensuring stable performance on offshore platforms like Bohai Bay. Our As568 O-rings and dustproof rings are specially treated to resist saltwater corrosion for 2,500 working hours.

• High-Torque & Casing Operations: Suitable for deep well, horizontal well, and casing operations, where power pliers, wrenches, and hydraulic systems operate under up to 34,000 N·m torque and 35MPa pressure. Our accessories are compatible with 800 520-S-160 Lug Jaw Assembly and BV-100 70 810 lever long, ensuring precise make-up and break-out of casing pipes up to 14.5″ diameter.

• Continuous Operation: Designed for 24/7 use, our accessories reduce replacement frequency—our bearings and shaft sleeves can operate continuously for 10,500 working hours, while our seals and hoses last 2,000 working hours, minimizing downtime for maintenance. This aligns with the demands of hydraulic power pliers, which require reliable performance for continuous drill pipe make-up and break-out.

Maintenance & Engineer’s Practical Tips (Avoid Costly Mistakes)

As an oilfield equipment engineer with 22 years of on-site experience, I’ve seen countless equipment failures caused by improper maintenance or using the wrong parts. Here are my practical tips to extend the life of your accessories and keep your equipment running smoothly—drawn from real on-site challenges:

• Seal & Dustproof Care: Check KHT7625-582 As568 O-Ring (29.75×2.75) and KHT7625-860 Dustproof Ring every 330 working hours. Replace them if you see cracks, hardening, or oil residue—reusing old seals will lead to leaks that can damage hydraulic systems. Remember, our O-rings comply with AS568 standards and are designed for -45℃ to 200℃ temperatures, so avoid using generic seals that can’t withstand these ranges.

• Pressure Gauge Maintenance: Calibrate KHT7625-603 Y-60ZT pressure gauge (0-3600PSI) every 6 months to ensure accuracy (its 1.5 accuracy grade is critical for safe operation). Keep the gauge clean and free of dust, and avoid subjecting it to excessive vibration—this can damage the internal mechanism and lead to incorrect pressure readings, which can cause equipment failure.

• Lubrication: Refill KHT5500-20 and KHT7625-84 GB/T1152 Grease cups (M6x1) with high-temperature grease (ISO VG 460) every 240 working hours. Lubrication is critical for transmission parts like KHT7625-429 Locating shaft sleeve and deep groove ball bearing 307—low lubrication causes excessive heat and premature failure. For new hydraulic power pliers, replace the hydraulic oil after one month of use, then every six months for regular maintenance.

• Fastener Check: Tighten KHT7625-356 Bolts, KHT7625-511 Hex bolts, and KHT7625-486 Cotter pins every 120 working hours. Loose fasteners cause vibration, which damages gear trains and jaw assemblies. Use the correct torque wrench setting—over-tightening strips threads, while under-tightening leads to loosening.

• Avoid Generic Parts: Never use generic parts as a "quick fix." For example, a generic KHT7625-429 Locating shaft sleeve may last only 2,900 working hours, while our precision-machined sleeve lasts 10,500 working hours. Always check the part number and model compatibility before installation to avoid equipment damage and downtime—generic parts often don’t meet AS568 or GB/T standards, leading to premature failure.
