In industrial maintenance, pipeline integrity, and countless manufacturing processes, the reliability of a seal is paramount. Leaks, whether of fluids, gases, or contaminants, can lead to catastrophic equipment failure, significant product loss, severe safety hazards, and substantial environmental impact. This is where the precision and durability of professional Sealing Tools become non-negotiable. Unlike generic hardware, specialized sealing tools are engineered to deliver consistent, high-pressure, leak-free seals across a vast spectrum of materials and operating conditions. At Kaxite, we have dedicated decades to refining this critical technology, developing a comprehensive range of tools that set the industry standard for performance, safety, and longevity.
The Kaxite product line is built on three foundational sealing technologies, each designed for specific applications and performance requirements.
Essential for safe and efficient maintenance of bolted flange connections on pipelines, valves, and pressure vessels. Traditional methods using pry bars are dangerous and can damage flange faces. Kaxite hydraulic flange spreaders apply controlled, even force to safely separate flanges for gasket replacement or inspection.
Designed for the precise removal of gears, bearings, pulleys, and other components press-fitted onto shafts. A proper seal during reinstallation often depends on a perfectly undamaged mating surface. Kaxite pullers apply concentric, radial force to remove components smoothly without damaging the shaft or the component itself.
For achieving precise, uniform preload on critical bolted joints. Accurate bolt load is the single most important factor in creating a reliable flange seal. Kaxite hydraulic tensioners stretch the bolt axially, allowing the nut to be run down finger-tight. When pressure is released, the bolt elastically contracts, creating a perfectly even and measurable clamp load across the entire gasket.
Our commitment to excellence is reflected in the precise engineering of every tool. Below are specifications for key models in our lineup.

Q: What makes Kaxite sealing tools different from other brands on the market?
A: Kaxite tools are distinguished by their precision engineering, use of high-grade forged alloys, and rigorous quality control. Every hydraulic component is tested at 1.5 times its maximum working pressure. Our designs focus on operator safety, ease of use, and long-term durability in harsh environments, reducing total cost of ownership through reliability and fewer tool failures.
Q: How do I select the correct flange spreader for my pipeline?
A: Selection is based on two primary factors: the flange size (OD and gap width when bolts are removed) and the required separating force, which can be influenced by gasket adhesion, corrosion, or system pressure. Always consult the Kaxite model guide, choosing a tool whose jaw opening range fits your flange gap and whose tonnage rating exceeds your estimated requirement by a safety margin of 20-30%.
Q: Can your bolt tensioners be used with any hydraulic pump?
A: Kaxite bolt tensioners are designed for use with ultra-high-pressure (UHP) hydraulic pumps, typically operating at 1500 bar. They require a clean, non-flammable hydraulic fluid (like Skydrol or equivalent) and a pump with sufficient flow rate to achieve tension efficiently. We recommend and offer compatible Kaxite UHP pump units to ensure optimal, safe performance and tool longevity.
Q: Are spare parts and servicing available for Kaxite tools?
A: Absolutely. Kaxite maintains a global inventory of genuine spare parts, including seals, pistons, jaws, and forcing screws. We offer detailed maintenance guides and provide factory-authorized service centers in key regions to perform overhauls, recalibrations, and pressure testing, ensuring your tools perform like new for decades.
Q: What safety protocols are critical when using hydraulic sealing tools?
A> Always wear appropriate PPE, including safety glasses and gloves. Never exceed the tool's maximum rated pressure. Ensure workpieces are stable and secured. Use load-spreading plates if needed to prevent point loading. For tensioning, follow a cross-bolting pattern to load the gasket evenly. Regularly inspect hoses and fittings for wear. The Kaxite user manual for each product provides comprehensive, step-by-step safety instructions.
Q: Do you offer custom sealing tool solutions for unique applications?
A: Yes, Kaxite's engineering team specializes in developing custom tooling for non-standard or extreme applications. This includes tools for unusual flange geometries, exceptionally high-temperature environments, subsea applications, or requiring specific material certifications (e.g., sour service, nuclear).
