XQ89/3YC Stop Pin & KHT5500-164 Sleeve Rod Oilfield Accessories Supply

Introduction: Reliable Accessories for XQ89/3YC, XYQ12 & TQ508/70Y Oilfield Power Tongs

In oil and gas drilling, well workover, and tubing operations, the smallest components often determine the safety and efficiency of your entire rig. From the critical KHT5500-164 TQ245.13.2-3 Sleeve rod that ensures smooth power transmission to the XYQ3C.B-4 XQ89/3YC stop pin that prevents accidental equipment movement, every part we supply is engineered to fit your most relied-upon equipment. Our product range is specifically tailored for XQ89/3YC pipe/tubing power pliers, XYQ12 pipe oil power pliers, TQ245 and TQ508/70Y tools, KHT5500/KHT7625/KHT8625 series tongs, and WRT-35 800 101, BV-35 70 410 lever-equipped equipment. Our core purpose is to solve the biggest pain points for oilfield operators, drilling contractors, and maintenance teams: frequent part failures, mismatched components, equipment jams, and unplanned downtime that cuts into productivity and profits. As XQ89/3YC power pliers are widely used for tubing connection and casing operations, and stop pins (like XYQ3C.B-4 and XYQ12.B-03A) are essential for operator safety, our accessories are designed to keep your operations compliant with industry standards like SY/T 5074-2012—implemented since March 1, 2012, and归口上报 by the National Technical Committee for Petroleum Drilling Equipment and Tools—and running smoothly, whether you’re in the Permian Basin’s dust, the Gulf of Mexico’s salt air, or the North Sea’s cold swells.

Product Overview: Durable, Standard-Compliant Oilfield Accessories

Our product lineup covers every critical accessory needed for pipe/tubing power pliers, lever tools, and related equipment, all manufactured to meet or exceed strict standards like GB/T276-82, GB/T288-1994, GB/T10708.1, GB/T10708.3, GB/T15242.2, SY/T 5074-2012, and API Spec Q1 (10th edition). We also comply with SAE J429 for fasteners, ensuring each part meets rigorous safety and performance requirements. With 23 years of hands-on experience supplying oilfield accessories, we hold ISO 9001, ISO 14001, and ISO 45001 certifications, and our products undergo strict testing under real-world conditions.

Key Product Features & Pain Point Solutions

1. Structural Characteristics

Every component is designed for durability and longevity, addressing the common issue of premature wear and failure. The KHT5500-164 TQ245.13.2-3 Sleeve rod is precision-machined from high-strength alloy steel, with a smooth surface finish to reduce friction and prevent jamming—solving the problem of power transmission failures that halt operations. Our XQ89/3YC stop pin (XYQ3C.B-4) is made from hardened steel, with a 12mm diameter and 45mm length, resisting bending and breakage even under 12 kN of shear force. The GB/T288-1994 Bearing 22314 features a spherical roller design, allowing it to compensate for minor shaft misalignment (up to 2.5°) and reducing wear on adjacent components. Even small parts like the KHT7625-773 ORing 22×2.4 adhere to GB/T3452 standards, with an inner diameter of 22mm and cross-section of 2.4mm, ensuring a tight seal in hydraulic systems and preventing leaks.

2. Functional Advantages

Our accessories are engineered to make your work easier and safer, solving daily operational frustrations. The KHT5500-314 Front Jaw Plate 6 (2 7/8″) provides a secure grip on tubing, eliminating pipe slippage that causes damage and delays. The KHT7625-928 GB/T10708.3 Dustproof Ring FA40x48x5 forms a tight barrier against dust and drilling fluids, protecting internal components and extending their life by 3,300 hours. The KHT5500-227 Hose 6II-600 (7/16-20UNF) features flared ends (one end 90°) for easy installation, reducing connection time by 22 minutes per hose, and its 600mm length fits most XQ89/3YC power pliers configurations. Our KHT7625-239 Inner gear sleeve ensures smooth gear engagement, reducing noise and wear, and preventing gear jams that cause unplanned downtime.

3. Applicable Working Conditions

Our accessories are built to perform in the harshest oilfield environments, perfectly matching the working conditions of XQ89/3YC power pliers, XYQ12 tools, and TQ245/TQ508/70Y equipment. They withstand extreme temperatures (ranging from -45℃ in the Bakken Shale to +115℃ in the Middle East), high humidity, and corrosive exposure to drilling fluids and seawater. Whether you’re operating in the dusty Permian Basin, the salty Gulf of Mexico, or the cold North Sea, our components will hold up—reducing the need for frequent replacements and unplanned maintenance. They’re compatible with casing operations, well workover, and tubing operations, meet the pressure requirements of hydraulic systems up to 45 MPa, and comply with SY/T 5074-2012 standards, making them a versatile solution for all your drilling needs. They also accommodate the high-speed demands of cylindrical roller bearings like the 3205, operating reliably at speeds up to 7,500 r/min.

Maintenance & Engineer Tips (Practical, On-Site Advice)

Our senior oilfield engineers, with 30+ years of on-site experience, have compiled these practical tips to help you maximize the life of your accessories and avoid common pitfalls—advice you can use directly on the rig, aligned with SY/T 5074-2012 standards and bearing maintenance best practices:

• Inspect XQ89/3YC stop pins (XYQ3C.B-4, XYQ12.B-03A) every 1,000 operating hours—replace if there’s any bending or wear (even 0.5mm wear can cause equipment misalignment, violating SY/T 5074-2012 safety requirements).

• Lubricate the GB/T288-1994 Bearing 22314 and KHT7625-242 Cylindrical roller bearing 3205 every 500 operating hours with ISO VG 68 high-temperature grease—dry bearings seize easily, reducing service life by 50% or more. For the 3205 cylindrical roller bearing, ensure lubrication reaches all contact surfaces to maintain its 7,500 r/min reference speed.

• Replace the KHT7625-928 Dustproof Ring every 8 months—dust and debris build up over time, reducing its effectiveness and risking internal component damage. Ensure the ring matches GB/T10708.3 dimensions (40x48x5mm) for a proper seal.

• Check the KHT5500-164 Sleeve rod every 2 months for bending or wear—even minor bending (0.3mm) can cause power transmission issues and damage adjacent components. Replace immediately if any deformation is found.

• Store small parts like KHT7625-773 ORing 22×2.4 and GB/T91 Split pin 6×45 in a dry, sealed container—corrosion from moisture reduces their strength, leading to seal failure or pin breakage in vibrating environments.
