Rancilio Z-11/LE No-Return Valve Washer

Beveled brass washer used in the circa-1989 Rancilio Z-11 LE lever group, working alongside a conical PTFE gasket as part of the no-return valve. Discontinued by Rancilio with limited stock remaining; Ascaso, which shares design lineage, may still carry some.

SPECIFICATIONS

  • Dimensions: 9 x 5 x 0.9mm
  • Material: brass, beveled

COMPATIBILITY

  • Fits: Rancilio Z-11 LE lever group (ca. 1989)
  • Works with: conical PTFE gasket (no-return valve assembly)

INSTALLATION

Technician-level install within the no-return valve stack, orientation matters.

PRO TIPS

  • This washer is beveled, install it with the bevel facing the same direction as the original, or the no-return valve will not seat properly and will weep water.
