Sealing lock Tapered face Fluid pressure Tubing support Main sealing A seal is formed when the tubing is inserted, with its insert bushing, and its compression against the internal nut. The fluid pressure pushes the seal face to get effective sealing. Reducing insert bushing Area of application Area of application D side sealing C side sealing By tapering the face of the body, perfect sealing is achieved by the pressure of the bushing against the body wall (the protrusion of the insert bushing ensures that a secure high pressure seal is achieved). B side sealing A side sealing Body class 1 and 2 2 stage pressing construction ensures sealing and tubing locking to absorb differences in the tube outside diameter. Main sealing Trapezoidal thread Sealed by the pressure exerted on the tubing by the internal nut. Quadruple sealing construction The quadruple sealing construction (PAT.) based on SMC’s original idea results in highly reliable sealing characteristics with outstanding leakage prevention effect. Strong resistance to tube bending and deformation. Able to withstand lateral loads with the tubing support. Tubing sizes are interchangeable. �� The reducer method allows tubing size changes without replacing the body. �� Helps standardize fitting items resulting in less stock requirements. Easy tightening of nuts. �� No positioning guide is required, simply tighten up the tubing to the end of the fitting body. �� The trapezoidal thread prevents oblique nut insertion. Reducing type Fluoropolymer Fittings Hyper Fittings Basic Flow-through characteristics Excellent flow-through characteristics are achieved by minimizing liquid deposit. Locking �� Locking mechanism utilizes sealing lock by the nut. �� Trapezoidal thread allows application of high torque. �� 2 stage pressing by the tubing holder of the nut ensures secure tube holding. 200°C compatible 736
