Pressure gauge 100 bar, 1/4" G female POS connection – code: 57369094 – HP Watermakers

The 100 bar pressure gauge with G 1/4″ female connection in rear configuration (POS) it is a spare part intended for pressure control instrumentation on systems HP Watermakers. Identified by code 57369094, it is designed for pressure reading in the high-pressure circuit, supporting operational verification and maintenance activities typical of reverse osmosis desalination systems.

Product identification

• Plant brand / manufacturer: HP Watermakers
• Spare part code: 57369094
• Description: 100 bar pressure gauge 1/4″ G female POS
• Component type: mechanical pressure gauge for high pressure
• Application: HP Watermakers reverse osmosis desalination systems

Features and details

This instrument is a mechanical pressure gauge designed for use on high-pressure lines, where immediate feedback of operating pressure is necessary. The POS configuration indicates the rear connection, useful when the pressure gauge is installed on panels or measurement points where access to the fitting is from the rear.

Technical data confirmed

• Measuring range: 0–100 bar
• Connection: G 1/4″ (female)
• Thread type: Gas BSP (G) (cylindrical, according to ISO 228)
• Connection configuration: Rear (POS)
• Instrument type: Mechanical pressure gauge

Note on G (BSP) threading

The code G identifies a Gas BSP cylindrical thread. When replacing, it is important to verify that the connection required by the system is actually G 1/4″ and that the mounting configuration is rear, so as to keep the existing installation unchanged.

Applications

The replacement 57369094 is intended for HP Watermakers desalination units equipped with high-pressure control instrumentation. In these systems, the pressure reading is a useful operational reference for:

• monitoring the high-pressure circuit pressure;
• checking the correct operation of the high-pressure pump;
• controlling the operating conditions of the reverse osmosis system;
• supporting diagnosis and routine maintenance.

Operational advantages

In a nautical and plant engineering context, the instrumentation must be clear and consistent with the original installation. This pressure gauge, thanks to its declared characteristics, allows maintaining the measurement point in accordance with the configuration provided by the system manufacturer.

• Identifiable spare part: code 57369094 for faster selection during maintenance.
• Integration with the system: attack G 1/4″ and configuration rear (POS) for replacements on compatible installations.
• Immediate check: pressure reading up to 100 bar for monitoring the HP circuit.
• Maintenance support: useful as a reference during functional checks and diagnostic activities.

Usage and notes for replacement

For a correct replacement, it is always recommended to compare the data of the installed component with those of the spare part:

• measuring range (0–100 bar);
• type and thread size (G 1/4″ Gas BSP);
• connection position (rear / POS);
• spare part code (57369094) and plant brand (HP Watermakers).

In case of doubts about the mounting configuration or installation point (panel, line, manifold), it is preferable to verify the correspondence with the plant documentation or with the removed component, to avoid differences in connection orientation or threading.

FAQ – Frequently Asked Questions
