DIMENSIONS (Flat Glass)

To obtain the maximum length permissible for given vessel center-to-center dimension using 1/2" nipples:

Maximum Gage Length =
(Valve Center-to-Center Dimension) - (Dimension X)

To determine the overall length of nipples needed to make up a gage set for fixed vessel center-to-center dimension using 1/2" nipples:

Combined Nipple Length =
(Valve Center-to-Center Dimension) - (Gage Length + Dimension Y)

Overall nipple length can be divided between nipples to suit the application. Minimum length required for each hipple is: 1-1/8" for 1/2" NPT nipple; 1-3/8" for 3/4" NPT nipple.

Penberthy Floating Shank union vessel connection permits valve center-to-center dimension to vary 3/8" (9.5 mm) total from actual vessel center-to-center dimension.
