Name: Festo 553938 Plastic tubing PUN-6X1-SW-500
Brand: Festo

Plastic tubing PUN-6X1-SW-500

Engineered from ester-based TPE-U in black with a Shore hardness of D 52 +/-3, this Festo industrial component features a 6 mm outside diameter and a 4 mm inside diameter. The tubing operates across a temperature-dependent range of -0.95 bar to 10 bar and an entire-temperature-range pressure of -0.95 bar to 7 bar within an ambient temperature range of -35 °C to 60 °C. Certified by TÜV under authority B 013277 0527 00, it is suitable for energy chains and utilizes compressed air as an operating medium according to ISO 8573-1:2010 [7:-:-].

Why 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.
