O-ring, 13 x 2 mm – Viton, Part# 38250008 – vacstellar

Description

This part is an O-ring. It’s a simple loop of rubber that sits in a groove between two parts. When squeezed, it fills the gap completely. This creates an airtight and sometimes fluid-tight seal.

But not all rubber is the same. This O-ring is made from Viton. Think of Viton as a strong suit of armor for a seal. It stands up to things that destroy ordinary rubber.

 Vacuum pumps often handle oils, solvents, or chemicals. They also get warm from running. Viton is famous for resisting these harsh conditions. It won’t swell, crack, or degrade easily.

This means a longer-lasting seal and more reliable pump performance. It’s a smart upgrade or direct replacement for seals in tough environments.
