Steam Wand O-Ring SES500 Manufacture pre 1848

What is the steam wand O-ring

The steam wand O-ring is a small sealing ring with a circular cross-section that sits on the body of the wand or milk frother and prevents steam and hot water from escaping outside the flow path. Thanks to it, the wand fits snugly into its seat and steam passes only where it should.

When the part stops doing its job

With age or exposure to heat and moisture, the material loses elasticity, hardens or cracks. This shows up as steam leaking around the wand, a weaker or uneven flow when frothing milk, water dripping at the wand's seat, or the wand sitting loosely and being easy to pull out or move.

Why replace this part in time

A leaking O-ring means loss of steam pressure, poorer milk foam and unnecessary strain on surrounding parts from moisture. Replacing it is a quick and inexpensive fix that restores both tightness and the frother's performance without touching the rest of the coffee machine.

How to choose the right part

Since the size and hardness of O-rings vary between models, check the exact compatibility with your coffee machine in the product's table.
