A precision hydraulic/pneumatic connector featuring dual counter-rotation prevention flats for wrench installation. The BU0202-S's nickel-plated brass construction provides excellent corrosion resistance while maintaining 25% higher torque tolerance compared to standard fittings. The chamfered thread entry (0.3mm×45°) ensures smooth assembly without cross-threading.
- Inline pressure sensor connections in hydraulic systems
- Modular pneumatic circuit assembly in packaging machinery
- Coolant line junctions in CNC machining centers
- Vacuum system interconnects for semiconductor equipment
- Medical gas delivery systems (stainless steel version)
Installation protocol:
Apply thread sealant (Loctite 545) or PTFE tape on male threads only.
Tighten to 1.2-1.5 N·m torque using 7mm open-end wrench.
Avoid overtightening beyond 2.0 N·m to prevent thread deformation.
