Astoria group O-ring in Viton® (FKM) — 47.22 × 3.53 mm
Part no. ET-100389
Group head o-ring in Viton® (FKM), 47.22 mm inner diameter with a 3.53 mm cord. It withstands hot water and constant steam and fits old-style Astoria group heads as well as Wega and Elektra.
It fits the group head of older Astoria models and also Wega and Elektra. Measure your current o-ring before ordering: 47.22 × 3.53 mm.
What are its measurements?
47.22 mm inner diameter and a 3.53 mm cord thickness. These are standard sizes, so confirm both figures rather than the diameter alone.
Why Viton® (FKM) rather than ordinary rubber?
FKM copes better with constant heat, hot water and group steam, and stays elastic for longer. It is a quality replacement part.
When should it be replaced?
When water leaks at the group, or when the o-ring is flattened, hardened or nicked. Lubricate it with food-grade grease before fitting and never force it into place.
