Festo
178423
Plastic tubing PUN-3X0,5-GN
The Festo 178423 is a green ester-based TPE-U industrial component featuring an outside diameter of 3 mm, an inside diameter of 2.1 mm, and a weight of 0.0044 kg/m. Designed with a Shore hardness of D 52 +/-3 and UL94 HB material fire test compliance, it operates within a temperature range of -35 °C to 60 °C and supports pneumatic connections for 3 mm outside diameter plug connections or 2 mm inside diameter barbed fittings. This TÜV certified tubing maintains an operating pressure of -0.095 MPa to 0.7 MPa across its entire temperature range and is suitable for energy chains when installed away from phosphoric acid ester cable sheathing.

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.
