The Flair Espresso Standard Brew Head Replacement O-ring Set includes six o-rings for maintaining the standard brew head and its accessories. The set covers the cylinder, plunger, stem, and gauge positions and is compatible with the PGK (Pressure Kit Gauge) assembly. It is not compatible with the SS Piston.
O-rings are the sealing components that hold pressure through every pull of the lever. Over time, heat cycling and repeated use cause them to compress, crack, or deform, leading to pressure loss and inconsistent shots. Replacing worn o-rings with a fresh set restores the tight seal the standard brew head needs to build and hold the pressure a good espresso extraction requires.
This set is matched specifically to the standard brew head and the PGK (Pressure Kit Gauge) assembly. The plunger o-rings and stem o-ring are confirmed compatible with the PGK. The gauge o-rings serve the pressure gauge port on PGK-equipped setups. Having the full set on hand means a single maintenance session can address every sealing point in the assembly at once.

This set is not suited to Flair owners using the SS Piston assembly. The plunger o-rings in this set are not compatible with the SS Piston, and SS Piston o-ring replacement requires a different service path.
This Flair Espresso replacement o-ring set is designed for the standard brew head and its accessories. It is not sized or shaped for the SS Piston assembly, and it is not listed as compatible with that component.
Yes. The plunger o-rings, stem o-ring, and both gauge o-rings in this set are confirmed compatible with the PGK assembly. The cylinder o-ring serves the brew head cylinder regardless of whether a PGK is installed.
The Flair Espresso Standard Brew Head Replacement O-ring Set includes six pieces: one cylinder o-ring, two plunger o-rings, one stem o-ring, and two gauge o-rings. Together these cover every primary sealing point in the standard brew head and PGK assembly.
This set does not include SS Piston-compatible plunger o-rings. SS Piston o-ring replacement requires a separate service path; this set cannot substitute for it.
