Festo
This blue Festo industrial component (Part Number 159664) is an ester-based TPE-U plastic pneumatic tubing featuring a 6 mm outside diameter, a 4 mm inside diameter, and a D 52 +/-3 Shore hardness. Certified by TÜV under certificate B 013277 0527 00, it operates with compressed air as per ISO 8573-1:2010 [7:-:-] at an ambient temperature range of -35 °C to 60 °C and supports energy chain applications with a minimum bending radius of 16 mm and a bending radius relevant for flow rate of 26.5 mm. The RoHS compliant and UL94 HB fire-tested tubing provides an operating pressure of -0.095 MPa to 0.7 MPa across its entire temperature range, scaling up to 1 MPa depending on temperature, while requiring cable sheathing free from phosphoric acid esters during installation.
