Festo
551440
Plastic tubing PEN-8X1,25-SW-400
Engineered by Festo, this black industrial component with part number 551440 features an 8 mm outside diameter, a 5.7 mm inside diameter, and a D 52 +/-3 Shore hardness with RoHS compliant materials. It operates within a temperature-dependent pressure range of -0.095 MPa to 1 MPa (-0.95 bar to 10 bar, or -13.775 psi to 145 psi) for compressed air and up to 0.6 MPa for water at 0 to 50 °C, supported by TÜV certification under authority B 013277 0527 00 and VDMA24364-B2-L LABS conformity. The tubing is suitable for energy chains, offering a 22.5 mm minimum bending radius and a 35 mm bending radius relevant for flow rate across an ambient temperature range of -30 °C to 60 °C at a weight of 0.02327 kg/m.

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.
