Precision-machined Y-fitting for 90° flow division in compact pneumatic systems. Features stress-relieved thread roots and anti-vibration locking grooves. Electroplated finish prevents dezincification in humid environments. Compatible with ISO 15407-1 pneumatic tubing.

Typical Applications:

• Modular pneumatic manifolds in packaging machinery
• Coolant line distribution in CNC tool changers
• Vacuum circuit branching for robotic end effectors
• Beverage dispenser pressure balancing systems
• Laboratory gas analyzer sample flow splitting

Installation guidelines: Apply 2-3Nm torque using flank-contact wrench. Use liquid thread sealant (PTFE-free recommended) only on male threads. Max angular deviation: ±3° from alignment axis. Not suitable for pulsating flows above 5Hz.

Media Compatibility: Compressed air (ISO 8573-1:2010 Class 2), inert gases, and HFD fire-resistant fluids. Not for use with ammonia, chlorine, or ester-based lubricants.
