Miniature One-touch Fittings One-touch Mini Series KJ ø4, ø6 Applicable Tubing: ø2, ø3.2, Release button (Light gray) Guide 1 Guide 2 Chuck Light force for removal When the fitting is removed from the tubing, the chuck and collet are released, thus preventing them from biting into the tube to an unnecessary degree. Unique shape allows easy tube release. Suitable for use with nylon, soft nylon and urethane. Large retaining force. The chuck provides a secure bite, while retaining force is increased. Seal Can be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa. Tube Body (White) O-ring The use of a special profile ensures sealing and reduces resistance when the tube is inserted. Stud Effective when piping in a confined space. • The body and the threaded portion can rotate (for positioning to some extent). • Stud is electroless nickel plated. • Standard with preapplied sealant for R 1/8 thread Optimum piping in less space with 20% reduction of the outside diameter. Thread with sealant is standard. Copper-free specifications (With electroless nickel plated.) Possible to use in vacuum to –100 kPa. Applicable Tubing FEP, PFA, Nylon, Soft nylon(1), Polyurethane ø2, ø3.2, ø4, ø6 Tubing material Tubing O.D. Note 1) Soft nylon tubing is not compatible with water.
