What it is

The Worcester Bosch 87161408200 is an O-ring with a 17.6 mm inner diameter and a 2.4 mm section. It is a sealing component used at pipe and component joints inside Worcester Bosch heating appliances, including heat exchangers, flues and similar assemblies. Its job is to close the gap between two mating faces so that water or gas cannot escape past the joint.

Signs this part needs replacing

  • Water weeping or a visible drip at a pipe or component joint
  • A gas smell, or a joint that fails a tightness test
  • The ring has hardened, flattened or cracked through age and heat cycling
  • Scale or debris sitting on the sealing face and breaking the seal
  • The ring was disturbed during a repair and no longer seats correctly in its groove
