Festo
The Festo 558303 industrial component is an ether-based TPE-U tubing with a 12 mm outside diameter, an 8 mm inside diameter, and a weight of 0.0729 kg/m, featuring suitability for energy chains and a 33 mm minimum bending radius (62 mm bending radius relevant for flow rate). It operates within a temperature range of -35 °C to 60 °C, supporting an operating pressure of -0.095 MPa to 0.6 MPa across its entire temperature range and -0.095 MPa to 1 MPa under temperature-dependent conditions for compressed air and water. Certified by TÜV under authority B 013277 0527 00, this component complies with UL94 HB fire tests, VDMA24364-B2-L LABS conformity, and is suitable for Li-ion battery production with reduced Cu/Zn/Ni values.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
For a faster response, include quantity, condition, and delivery destination.
