Festo
525741
Plastic tubing PUN-8X1,25-SI-400
The Festo 525741 is a silver industrial pneumatic tubing manufactured from ester-based TPE-U with a Shore hardness of D 52 +/-3 and a weight of 0.0302 kg/m, featuring an 8 mm outside diameter and a 5.7 mm inside diameter. Certified by TÜV under authority B 013277 0527 00 and compliant with UL94 HB fire testing, VDMA24364-B2-L LABS conformity, and RoHS standards, this tubing is suitable for energy chains within an ambient temperature range of -35 °C to 60 °C. It operates at pressures from -0.095 MPa to 0.7 MPa across the entire temperature range, and up to 1 MPa under temperature-dependent conditions, using compressed air as per ISO 8573-1:2010 [7:-:-].

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.
