Valve Pin and Seal for 9Barista Espresso Machine

This is a replacement valve pin and O-ring seal for the 9Barista espresso machine, compatible with both Mk.1 and Mk.2 models.

The valve pin, made from PTFE, is designed for durability and heat resistance. PTFE provides a smooth, low-friction surface that helps ensure consistent valve movement and pressure regulation during espresso brewing.

The included O-ring is made from food-grade silicone rubber, forming a tight seal around the valve pin. This prevents leaks and maintains the correct brewing pressure for optimal espresso extraction.

These parts rarely require replacement under normal conditions, but can become worn or damaged with heavy use or overheating. If you’re experiencing issues with pressure stability, leaks, or inconsistent shots, replacing the valve pin and seal can help restore your machine’s performance.

Materials:
– Valve pin: PTFE
– O-ring: Silicone rubber
– O-ring size: 6mm internal diameter, 2mm cross section
