What reference identifies this O-ring?

The supplied listing gives supplier reference 36402001. Match it against the seal reference in your machine's parts diagram before ordering.

Is this O-ring listed for the Rancilio Silvia?

Yes. Silvia, Silvia-E and Silvia-M versions appear in the supplied compatibility list. Check the version references above and the exact sealing position in your parts diagram.

What are its dimensions?

The original designation is “607 × 178”, without explicit units or decimal placement. Confirm the internal diameter and cross-section before purchasing; do not treat this designation as verified measurements.

What does EPDM 105 mean?

EPDM is the listed material designation. The meaning of “105” is not defined in the supplied information and should not be interpreted as a temperature or hardness rating.

Will replacing this O-ring stop a leak?
