Festo
159666
Plastic tubing PUN-8X1,25-BL
The Festo 159666 is an ester-based TPE-U industrial plastic tubing in blue with an 8 mm outside diameter, a 5.7 mm inside diameter, and a Shore hardness of D 52 +/-3. It features a minimum bending radius of 24 mm, a flow rate bending radius of 37 mm, suitability for energy chains, and operates within a temperature-dependent pressure range of -0.95 bar to 10 bar and an entire temperature range pressure of -0.95 bar to 7 bar at ambient temperatures between -35 °C and 60 °C. Certified by TÜV under authority B 013277 0527 00 with UL94 HB material fire testing and VDMA24364-B2-L LABS conformity, it utilizes compressed air as an operating medium per ISO 8573-1:2010 [7:-:-] and is compatible with 8 mm plug connections, 6 mm inside diameter barbed fittings, and 6 mm inside diameter barbed fittings with union nuts.

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.
