PTFE Teflon Tubing, 2mm ID X 4mm OD White Connector Tube for 1.75mm Filament for 3D Printer(10FT Length)

【Size】2mm(2/25") ID x 4mm(5/32") OD；Length:3M(10FT) 【Product Data】-454 to 500 Degree F；Flame rating: UL-224 VW-1(UL-recognized). 【Material】Made from high quality PTFE. It has excellent resistance to chemical corrosion, almost does not react with any chemicals, is resistant to strong acids and alkalis, and has good electrical insulation and low dielectric constant. It meet for ing with food contact surfaces. 【Low friction】With the smallest friction coefficient in plastics, PTFE tubing is a high-quality oil-free lubricating material- ideal for smoothly tracking the moving 3D printer head. For 1.75mm filament. 【Widely ed】It can be applied in fields such as ultra pure liquid transportation systems in the semiconductor indtry, transportation pipelines for chemical reagents and strong acid-base solutions, as well as insulation sleeves for wires and cables under high temperature and high pressure. At the same time, due to its good biocompatibility, it is also ed in medical equipment manufacturing.
