Product Overview

The Nilfisk Flow Switch Housing Ø22x86 M16x1 (SKU: 62722) is a brass flow sensor body designed for use in Nilfisk hot water pressure washers.

This housing contains a magnetic shuttle that moves with water flow. As the shuttle rises, it is detected by an external reed switch, allowing the system to confirm water flow and operate safely. If no flow is detected, the system remains open circuit to protect the boiler from dry running.

Manufactured from durable brass, this component is built for long-term reliability in demanding environments and is a key part of the machine’s safety system.
