Festo
558257
Plastic tubing PUN-H-4X0,75-BL-500
The Festo 558257 is an ether-based TPE-U industrial component featuring a 4 mm outside diameter, a 2.6 mm inside diameter, and an 8 mm minimum bending radius that extends to 16 mm for optimal flow rate. Constructed for energy chains, it operates within a temperature range of -35 °C to 60 °C and handles pneumatic pressures from -0.095 MPa to 0.6 MPa across all temperatures, or up to 1 MPa with temperature dependency. Certified by TÜV under authority B 013277 0527 00, this element supports compressed air as per ISO 8573-1:2010 [7:-:-] and ice-free liquid water while meeting UL94 HB and VDMA24364-B2-L LABS conformity standards.

Request a QuoteWhy no listed price?
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.
