101 Applicable Tubing Specifications Principal Parts Material Can be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa. The use of a special profile ensures sealing and reduces resistance when the tube is inserted. Effective when piping in a confined space. The body and the threaded portion can rotate (for positioning to some extent). Seal Stud Release button (Light gray) O-ring Body Gasket Chuck Guide Note 1) The surge pressure must be under the maximum operating pressure. Note 2) Do not use the fittings with a leak tester or for vacuum retention because they are not guaranteed for zero leakage. A ridge shape has been created as a Uni thread for common applications for Rc, G, NPT and NPTF. The male thread for piping drastically cuts piping manhours. Uni thread Uni thread ridge shape A gasket made of a stainless sheet covered with laminated NBR on both sides is seated on the chamfer of a female thread for a perfect sealing construction irrespective of the difference in thread diameters due to the difference in the types of female threads, variation in tolerance, or difference in the size of chamfer. (It is applicable to any female thread with an ordinary chamfer.) Suitable for use with nylon and urethane. Large retaining force. The chuck provides secure retention and the collet increases the holding force on the tube. Requires little force for removal. Releases the chuck collet to remove the tube as well as to prevent the chuck from biting too deeply into the tubing. Made to Order Specifications (Refer to page 107 for details.)
