3 Antistatic One-touch Fittings Series KA Seal Can be used for a wide range of pressures from low vacuum up to a pressure of 1.0 MPa. The use of a special profile ensures sealing and reduces resistance when the tube is inserted. Chuck Large retaining force Has large retaining force while holding force is increased by the collet. Stud Effective when piping in a confined space. The body and the threaded portion can rotate (to the degree for positioning). Release Button (Black) Light force for removal When the fitting is removed from the tubing, the check and collet are released, thus preventing them from biting into the tube excessively.

C3604BD is all electroless nickel plated. . PBT parts have conductive (104 to 107 Ω) and flame resistant applications. (equivalent to UL Standard V-0) . Conductive NBR (104 to 107 Ω) is used for seals. Tubing material Tubing O.D.

(With taper threaded screws it is necessary to apply a sealant to the thread, which electrically insulates the fittings causing it to become charged.)
