- Operating Pressure: 0.5-1.5 MPa (72.5-217.5 PSI)
- Burst Pressure: ≥3.0 MPa
- Temperature Range: -20℃ to 80℃ (-4°F to 176°F)
- Seal Material: NBR (Nitrile) O-rings (optional FKM available)
- Surface Roughness: Ra ≤1.6μm at sealing surfaces
- Weight: 20g ±2g
- Dimensions: 25mm(L) × 18mm(W) × 15mm(H)
- Flow Coefficient: Cv ≈0.15
- Vibration Resistance: 10-55Hz, 1.5mm amplitude
Precision-machined Y-connector featuring triple-port flow distribution with 120° branch angle design. The electroless nickel plating provides enhanced chemical resistance against hydraulic fluids and mild corrosives. Optimized internal channels minimize pressure drop during fluid/pneumatic transmission.
- Pneumatic circuit branching in CNC machine tool manifolds
- Coolant line distribution in semiconductor manufacturing equipment
- Modular pneumatic systems requiring compact branching solutions
- Vacuum system instrumentation with multiple sensor connections
- Medical gas delivery systems (oxygen/nitrogen distribution)
Installation Guidelines:
Apply PTFE tape clockwise on male threads (2-3 wraps). Hand-tighten until snug,
then use a torque wrench to 1.2-1.5 N·m. Avoid cross-threading – align branch
port direction before final tightening. Perform pressure test at 1.25× operating
pressure after installation.
