KHT5500 Series & XYQ12.Z-25 Oilfield Power Tong Accessories

Introduction: End Drilling Downtime with Precision-Matched Oilfield Spare Parts

Every oilfield operator knows the frustration of unexpected equipment failure—especially when it’s caused by a worn O-ring, faulty jaw assembly, or broken adapter. In drilling operations, even a 30-minute downtime can cost thousands in lost productivity, not to mention the safety risks of using ill-fitting or low-quality spare parts. Our comprehensive range of oilfield power tong and caliper accessories is engineered to solve these pain points, with parts specifically designed to fit critical equipment models like XYQ12, XQ89/3YC, KHT5500, KHT7625, KHT8625, and NXQ140/20Y. Whether you’re a drilling contractor, on-site maintenance technician, or equipment manager, we provide the exact parts you need to keep your pipe oil power pliers, tubing wrenches, and power calipers running smoothly—no guesswork, no mismatches, just reliable performance when you need it most.

Our core purpose is to supply high-quality, industry-compliant spare parts that reduce downtime, extend equipment lifespan, and ensure safe, efficient drilling operations. Every part in our lineup—from the XYQ12.Z-25 Brake Disc Assembly and KHT5500-220 YG-58 Adapter Connector to the GB1235-76 O-ring and 70 883-S Lug Jaw Assembly—meets or exceeds global standards, including API 7K (for drilling equipment components) and GB/T standards (GB1235-76, GB/T93-1987, GB/T882-1986). Backed by rigorous testing, each part undergoes 14 quality inspections before leaving our facility, with a proven service life of 3,100 operating hours—far surpassing the industry average of 1,600 hours for comparable components. We don’t just supply parts; we provide peace of mind, knowing your equipment will perform when you’re up against tight deadlines and harsh field conditions.

Product Overview: Essential Spare Parts for Oilfield Power Equipment

Key Product Range & Equipment Compatibility

Our spare parts portfolio covers every critical component of oilfield power tools, with a focus on the most in-demand models and applications. We specialize in parts for pipe oil power pliers (XQ89/3YC), tubing wrenches (XYQ12), power calipers, and power distribution equipment (NXQ140/20Y), including core series like KHT5500, KHT7625, KHT8625, and KHT9625. Our parts are precision-machined to match the original equipment specifications, ensuring a perfect fit without modifications—eliminating the common headache of mismatched parts that cause leaks, jams, or premature equipment failure. Key parts include the XYQ12.Z-25 Brake Disc Assembly (for XYQ12 tubing wrenches), KHT5500-220 YG-58 Adapter Connector (M22x1.5/M24x1.5), 70 883-S Lug Jaw Assembly, and KHT5500-253 GB1235-76 O-ring 35×3.1, as well as a full range of bolts, washers, bearings, and control components.

Function & Value: Solving Your Most Pressing Field Problems

Each part we supply is designed to address the specific pain points oilfield teams face daily—from frequent part replacements to costly downtime. Here’s how our key components deliver real value:

• Brake Disc & Friction Plates (XYQ12.Z-25, XYQ12.Z-36): Prevent brake failure and ensure smooth, controlled stopping of power tongs—solving the problem of unexpected jolts that damage pipe threads or equipment. Our brake disc assembly handles up to 130,000 N·m of torque, while the friction plates resist wear for 1,400 operating hours (double the industry average of 700 hours).

• Jaw Sets & Plates (70 883-S, KHT7625-66, KHT5500-24): Eliminate pipe slippage during makeup/breakout operations with hardened alloy steel construction. Our jaw sets (available in 7 5/8″ and 6 5/8″ sizes) grip pipe securely, reducing thread damage and ensuring consistent torque application—saving you time and money on pipe repairs.

• Adapters & Connectors (KHT5500-220, KHT7625-626): Solve compatibility issues between different equipment components with precision-machined adapters. The KHT5500-220 YG-58 Adapter (M22x1.5/M24x1.5) connects hydraulic lines without leaks, while the YG-68 Adaptor (NPT1/4H) ensures a tight seal for fluid systems—preventing pressure loss and equipment inefficiency.

• Seals & Washers (KHT5500-253, GB/T93-1987): Stop hydraulic leaks and protect sensitive components with high-quality O-rings and spring washers. The KHT5500-253 GB1235-76 O-ring (35×3.1) is designed for high-pressure environments (up to 4,000 PSI) and resists drilling mud and chemicals—eliminating unplanned stops for leak repairs.

Structural Features: Built to Withstand Oilfield Toughness

Oilfield conditions are unforgiving—dust, mud, extreme temperatures, and constant vibration can destroy low-quality parts in weeks. Our spare parts are engineered with structural features that prioritize durability and long-term performance: All metal components (jaw sets, bolts, brake discs, adapters) are made from high-strength carbon steel or alloy steel, heat-treated to a hardness of HRC 48-52 to resist impact and wear. Seals are crafted from nitrile rubber or fluorocarbon, withstanding temperatures from -45°C to 190°C and compatible with all common drilling fluids. Precision machining ensures tight tolerances (±0.015mm) for every part, guaranteeing a seamless fit with your existing equipment. For example, the XYQ12.Z-25 Brake Disc features a corrosion-resistant coating that prevents rust in offshore or humid environments, while the KHT5500-230 Hexagon Bolt (1/2″UNCx4 1/2″) has a reinforced thread design to resist loosening under high vibration.

Applicable Working Conditions

Our spare parts are designed to perform reliably in the most challenging oilfield environments, including:

• Land and offshore drilling rigs (compatible with XYQ12, XQ89/3YC, and KHT5500 series power tools rated up to 130,000 N·m torque)

• Extreme temperature ranges (-45°C to 190°C), suitable for cold northern fields and hot desert operations

• High-pressure hydraulic systems (up to 4,000 PSI), compatible with NXQ140/20Y digital ruler controller assemblies

• Corrosive environments with drilling mud, saltwater, and harsh chemicals

• Heavy-load operations (handling pipe sizes from 5/8″ to 7 5/8″, supported by our diverse jaw sets and dies)

On-Site Maintenance & Engineer Tips

Based on 22+ years of on-site oilfield experience, our senior engineers have compiled practical tips to help you maximize the lifespan of your spare parts and equipment—avoiding common mistakes that lead to costly downtime:

• Daily Inspection: Check friction plates (XYQ12.Z-36) for wear—replace when the thickness drops below 3.2mm. Inspect O-rings (KHT5500-253) for cracks or swelling, and clean adapter connectors (KHT5500-220) to remove mud buildup, which can cause leaks.

• Torque Specifications: When installing hexagon bolts (KHT5500-230, KHT5500-146), use a torque wrench set to 55 ft-lbs (for 1/2″ size) to avoid over-tightening, which can strip threads or damage components. For smaller bolts (M8, M10), set torque to 25 ft-lbs and 38 ft-lbs respectively.

• Seal Replacement: Replace GB1235-76 O-rings every 7 months or immediately if leaks are detected. Never use generic seals—they don’t meet API 7K standards and can fail under high pressure, leading to hydraulic system damage.

• Lubrication: Apply high-temperature grease to jaw rollers (Z1 12) and bearing seats (KHT7625-235) weekly—this reduces friction and extends component life by 800 operating hours. Avoid using low-grade grease, which breaks down in extreme temperatures.

• Risk Avoidance Tips: Don’t mix and match different brands of jaw sets or dies. Our KHT7625-66 Jaw Set (7 5/8″) is specifically designed for KHT8625 series tongs—using a generic jaw set can cause pipe slippage and thread damage, leading to costly rework.
