This dual trap assembly is designed for use with AF-0060 or AF-0061 manifolds. Pre-trap (B) is 51 mm O.D. x 250 mm long with 28/15 polished socket joints to connect the line shut off adapter (A) to the main trap stopper assembly (C), which has 28/15 O-ring ball joints. The main trap (D) has a 57 mm flat O-ring joint and the body is 57 mm O.D. x 250 mm long. The center-to-center distance between the traps is 175 mm. Connection to the manifold is made via a #15 O-ring joint (E) while the fore-pump is connected to the main trap assembly at port F. A #15 O-ring joint (G) between the main and pre-trap permits connection of vacuum measurement devices via a AF-0306-01 thermocouple adapter. Both traps can be isolated from the manifold or pump via 0-12mm Chem-Cap® valves (H). The complete item is supplied with one CG-305-331 #331 Viton® O-ring, one CG-139-02 horseshoe clamp, three #116 Viton® O-rings, and two CG-150-05 #28 stainless steel clamps.
