This critical component is an indispensable OEM replacement, engineered from high-grade Polytetrafluoroethylene (PTFE)—a material prized for its extreme heat resistance, low friction, and chemical inertness. The PTFE bush is designed to provide the sealing and gliding surface within the steam valve assembly, ensuring that the steam wand moves freely and that no high-pressure steam escapes. This small yet vital part addresses common issues like "why is my Strada steam valve stiff?" or "espresso machine steam wand leaking near the knob," offering a durable solution to prevent costly steam loss and enhance the barista's control.

The key features of this Steam Valve PTFE Bush include its precision machining for a perfect fit inside the Strada steam valve, guaranteeing reliable sealing performance under high boiler pressure and temperature.
