Festo
The Festo part number 4101 is a T-shaped industrial component featuring an 11.7 mm nominal width, an external thread G1/2 pneumatic connection 1, and a pneumatic connection 2 for a 13 mm inside diameter barbed fitting with a nut. It operates within a pressure range of -0.095 MPa to 1 MPa (-0.95 bar to 10 bar, -13.775 psi to 145 psi) using compressed air as per ISO 8573-1:2010 [7:-:-], accommodating lubricated operation across an ambient temperature range of -10 °C to 60 °C in any mounting position. Constructed with a die-cast zinc housing and swivel joint, an anodized wrought aluminum alloy hollow bolt and union nut, and a sealing ring of PA-reinforced TPE-U(PU), this RoHS-compliant unit exhibits a CRC 1 corrosion resistance class and requires a nominal tightening torque of 14 Nm with a ±20% tolerance.
