Brass Packing Nut, 7/8-20

The Brass Packing Nut is used in the DELTA, DELTAI, A200, A200I, A2000 & A2000I Fiber Instruments.  When properly tightened this ensures that the packing materials create a seal and prevent leaks from the vessel into the interior cabinet. 

For the A200/A200i instruments, refer to document 04-Packing and Agitator Replacement (A200/A200i) shown below.
