Sanremo 10857022C – 1/8" Full Cap Connector for Espresso Machine Hydraulic Systems The Sanremo 10857022C 1/8" Full Cap Connector is a precision-machined sealing component used within the hydraulic and boiler circuit of commercial espresso machines. Designed to securely close off unused 1/8” threaded ports, this cap ensures pressure stability and leak-free operation in high-temperature environments. In commercial machines, small threaded ports are often provided for testing, pressure gauges, safety valves, or future accessory connections. When not in use, these openings must be properly sealed to maintain system integrity. This full cap connector does exactly that — providing a tight mechanical seal that protects the internal water circuit from pressure loss and contamination. Manufactured to meet Italian espresso machine standards, this fitting is commonly found in Sanremo hydraulic assemblies and is compatible with machines using standard 1/8” threaded brass fittings in their steam or brew water circuits. Whether you’re replacing a worn cap or sealing a newly modified line, this part ensures reliable performance under continuous commercial use.
