Screw-in connection SCHAERER Spare Parts 3370062426

A screw-in connection creates a leak-proof joint between two threaded ports in a fluid circuit. The male thread on the fitting mates with the female thread in the port, while the O-ring compresses to seal the interface. This method is used where the joint must withstand pressure and vibration without loosening or leaking, such as water and steam lines in espresso machines and bean-to-cup units.

The operator aligns the fitting with the port, starts the thread by hand to prevent cross-threading, then tightens with a spanner until the O-ring is fully seated. No additional sealant is needed; the O-ring provides the seal once the fitting is torqued to specification.

The fitting is machined from brass, a material chosen for its corrosion resistance, thermal conductivity and compatibility with potable water. An O-ring is pre-fitted into a groove on the fitting to ensure consistent sealing.

This spare part is a direct replacement for the screw-in connections used in SCHAERER coffee equipment, maintaining the original pressure rating and flow characteristics of the circuit.
