What it is

The Glow-worm S208732 is an O-ring with a 21.82mm diameter and 3.53mm cross-section, used as a sealing component in Glow-worm Compact series gas boilers.

  • Visible water weeping or damp staining around the joint the O-ring seals
  • The O-ring has hardened, cracked or flattened in section
  • The O-ring has swollen or deformed after contact with system water or inhibitor
  • Traces of gas escape detected at the sealed connection during a tightness test
  • The O-ring is damaged or nicked after the joint has been disturbed

Before you order
