KQB2 Series Stainless Steel one touch fitting

The KQB2 series stainless steel one touch fitting adopts high-grade stainless steel integrated molding technology, which is specially designed for fluid transmission scenarios that require fast disassembly and reliable sealing, meeting the comprehensive requirements of cleanliness and durability in industrial environments.

Core features
Material stability: The all-stainless steel structure has native corrosion resistance, avoids the risk of medium contamination, and adapts to acid-base environments and temperature and pressure fluctuations
Instantaneous locking mechanism: Push-pull one-way lock design realizes blind operation connection, and built-in self-compensating sealing ring eliminates leakage risks
System compatibility expansion: Supports modular series connection of multiple pipe diameters, allowing flexible configuration of branch nodes in complex pipelines
Maintenance cost optimization: The tool-free disassembly and assembly feature greatly shortens equipment downtime, and the retaining spring structure can be replaced independently to reduce maintenance expenses
