Screw-in connection SCHAERER Spare Parts 3370072301

A screw-in connection creates a threaded joint that pulls two parts together under controlled torque. The male thread on the connector mates with a female thread in the machine block, forming a seal that resists vibration and pressure without leaking. This method is used where frequent disassembly is not needed and where the joint must hold against the internal pressures of hot water, steam or compressed air in beverage equipment.

The operator aligns the connector with the tapped hole, starts the thread by hand to prevent cross-threading, then tightens it with a spanner until the specified torque is reached. Once installed, the joint remains secure until the next service cycle.

This connector is made of stainless steel, chosen for its resistance to corrosion and scaling in wet, high-temperature environments typical of coffee and water-boiling systems.

The 4-M5 designation indicates four separate M5 threads, allowing a single component to secure multiple lines or sensors simultaneously. Each thread follows the metric M5 standard, ensuring compatibility with the corresponding tapped holes in the equipment.

Cleaning is limited to wiping the external surfaces with a damp cloth to remove any residual coffee oils or scale; the internal threads should not be exposed to cleaning agents that could leave deposits and interfere with the seal.
