ASTM Material Designations
SOR uses all ASTM grade materials in the construction of mechanical level switches. The following chart
lists the specific ASTM (or UNS) materials that are normally used for each component in our switches.
Consult the factory if you do not see the specific material required for your application.
Notes
1. UNS numbers are given in parenthesis for special alloys.
2. These materials are available by special order only.
Ring Tight Joint Flanges (RTJ)
The side surfaces of RTJ gasket surfaces shall not exceed 63µ” (1.6µm) roughness per ANSI B16.5.

Level Switches
Raised Face Flanges (RF)
All raised-face flange finishes are given as a range. AARH (Average Arithmetic Root Height) values are
given with their metric equivalent.
Flange Face Finishes
The most common flange face finishes are shown. SOR standard flange finishes are
highlighted.
