Ashcroft B424B 3000 Pressure Switch 3000 Psi 1/4 in Female

Product Description

The ASHCROFT B424B 3000# is a watertight single setpoint pressure switch designed for industrial and commercial fluid system monitoring and control. The switch activates at a single preset pressure point, making it well suited for pump control, compressor protection, and process automation applications where a discrete on/off signal is required. The watertight housing provides protection against moisture ingress, allowing reliable operation in demanding environments. Rated to a maximum pressure setting of 12000 psi, the B424B 3000# is built to handle high-pressure systems. Connection is made through a 1/4 inch female NPT thread port. Licensed instrumentation technicians, licensed plumbers, and licensed HVAC mechanics are the typical trades involved in specifying and installing this type of pressure switch.

This pressure switch is suited for use in high-pressure hydraulic systems, compressed air systems, water treatment equipment, and industrial process piping where a single setpoint trip signal is needed. The watertight construction makes it appropriate for wet, outdoor, or wash-down environments. Its compact form factor allows installation in space-constrained panel or inline configurations. It is not intended for flammable gas service unless the associated controls are rated and installed in accordance with applicable codes.

Key Features

• Watertight housing for reliable performance in moisture-exposed environments
• Single setpoint design provides a discrete on/off control signal at the set pressure
• Maximum pressure setting of 12000 psi supports high-pressure system applications
• 1/4 inch female thread connection for straightforward inline installation
• Compact design suitable for space-constrained installations

Compatibility

Designed as an OEM-style or replacement single setpoint pressure switch for high-pressure industrial, hydraulic, and fluid process systems requiring a 1/4 inch female threaded pressure port connection.

Installation Notes

Installation should be performed by a qualified instrumentation technician, licensed plumber, or licensed HVAC mechanic in accordance with applicable local codes and the system manufacturer's specifications. Depressurize and isolate the system completely before removing any existing pressure switch or installing this unit. Verify that the system's maximum operating pressure does not exceed the rated maximum pressure setting of the switch. Use appropriate thread sealant compatible with the system media on the 1/4 inch female thread connection.
