Airtac X-EPH External Hex Elbow Connector X-EPH4M8
AirTAC X-EPH4M8 Hex Elbow Joint Technical Details
- Full Model: X-EPH-4M8 (ISO 15407 standard)
- Thread Specification: M8×1.25 male thread (ISO 1179-2 compliant)
- Material: Carbon steel with nickel plating (base)/POM (rotating section)
- Max Installation Torque: 2.5-3.0 N·m (lubricated condition)
- Pressure Range: 0-1.0 MPa (14.5-145 psi)
- Temperature Range: -20℃ to 80℃ (static)/-5℃ to 60℃ (dynamic)
- Surface Hardness: HV550±50 (nickel-plated layer)
- Rotation Angle: 360° continuous rotation capability
- Weight: 19.8±0.5g (including packaging)
- Dimensions: 28mm(L) × 16mm(W) × 16mm(H) (body only)
- Hex Size: 8mm AF (across flats)
- Leakage Rate: ≤3×10⁻⁴ Pa·m³/s (under 0.6 MPa)
- Vibration Resistance: 10-55Hz, 1.5mm amplitude
Precision-engineered pivot joint featuring anti-vibration lock nuts and smooth 360° swivel action. The nickel-plated surface provides enhanced corrosion resistance against water-based coolants and mild chemicals. Optimized flow path design reduces pressure drop by 18% compared to standard elbows.
- Robotic arm end-effector pneumatic tooling
- CNC machine tool coolant line connections
- Semiconductor wafer handling vacuum systems
- Packaging line rotary union air supply
- Automated test equipment sensor interfaces
Installation protocol:
Apply thread sealant (LOCTITE 542 recommended) on male threads before assembly.
Tighten using 8mm crowfoot wrench with torque limiter. Avoid overtightening beyond
3.2N·m to prevent POM component deformation. Perform pressure test at 1.25×
working pressure after installation.
