TEMPERATURE RANGE -20° to +400° F | -40° to +200° F
PRESSURE RANGE 0 to 2,000 PSI | 0 to 5,000 PSI
SPEED 3 FT/SEC
PART NUMBER (Prefix)(CS) – (Inside Dia) – (Height)
Standard
Height and cross section
are equal, thus giving a square seal.
Utilizes type 'D' lip
Typical Part Number P25-02.500
Deep
Utilizes the same 'D' lip, but the seal height is greater than the cross section, thus giving
a retangular shape.
Typical Part Number P25-02.500-37D
Type B
Same dimensions as the Deep seal. Beveled lip design provides better film breaking.
Utilizes type 'B' lip.
Typical Part Number
U25-02.500-37B
