DeltaMate EPDM soft tubes are made from exceptionally high-quality, ozone- and UV-resistant EPDM (ethylene-propylene-diene rubber). EPDM also offers high resistance to chemical substances (acids and alkalis) and, thanks to its excellent temperature resistance, can be used in continuous operation within a range of -30 C to +110 C. EPDM also retains high elasticity at low temperatures. The EPDM tubes are compatible with all common PC water-cooling fluids. The DeltaMate Soft Tube - ST13 EPDM soft tubes in black feature a 10 mm inner diameter and 13 mm outer diameter. The small outer diameter allows the soft tube to be used even in very confined spaces. The tubes are subject to strict quality control with regard to tolerances of the inner and outer diameters and are optimized for use with TG fittings. To provide maximum flexibility during use, the tubes are shipped in one 3 m long piece.
