SMC's 2-layer soft fluropolymer tubing, series TQ, has a special nylon resin outer layer and an inner layer of special fluropolymer.  The internal smoothness of the TQ's inner layer is equivalent to Ra 0.02µm, and because the TQ is translucent it helps in identifying fluid color. Compared to SMC's TL series, flexibility has been improved by up to 55%, and the weight has been reduced by approximately 44%. The TQ is an excellent choice for use in automobile, semiconductor, food, medical and machine tool industries.
