819M-PFR-SF-1.5V2 Port Frame Reducer, 1.5 to 1 in. Port, Barium Sulfate, 819C and 819D Spheres

The 819M-PFR-SF-1.5V2 (P/N 7Z08362N) Port Frame Reducer mounts onto the 1.5 inches port frame to change the port frame to 1 inch diameter. This allows accessories designed for smaller port sizes to be used with larger port frames. The 0 degree port of Newport's 3.3 and 4 inch spheres are 1.5 inches diameter. Barium sulfate (spectraflect) coating. Tighten with two M3 size set screws using a 1.5 mm allen wrench, which are included with the part.
