O-ring, 75.56 x 5.33 mm - Viton, Part# 320521
O-ring, 75.56 x 5.33 mm - Viton, Part# 320521
This is an O-ring. Its part number is 320521. An O-ring is a simple loop of elastic material. Its shape is a perfect circle. When you look at a cross-section, it looks like the letter “O”. That is where the name comes from .
You place this O-ring into a groove between two metal parts. When you tighten the parts together, the O-ring gets squished. It fills the tiny gap completely. This creates an airtight, leak-proof seal.
This O-ring is made for two Pfeiffer DUO pump models :
Pfeiffer DUO 120A
Pfeiffer DUO 125
If you own either of these pumps and are doing any internal repair or rebuild, you will need this O-ring.
