Pressure regulator – code: 44411-1045 (3104441110) – Jabsco

Jabsco pressure regulator for connection to the marina water network

The Jabsco pressure regulator (code 44411-1045, reference 0392904030) is designed for use in nautical and plant engineering contexts, when desired connect the onboard water system to the harbor water network keeping the input pressure within a controlled value. It is a practical solution to manage dockside supply and reduce the risk of unwanted stresses on pipes, fittings, and system components.

The device limits the incoming water pressure and contributes to a smoother operation of the system when the external network pressure may vary. It is suitable for installations requiring an orderly connection compatible with common garden/nautical fittings, thanks to the provided inlet and outlet threads.

Features and construction details

This regulator is designed for simple installation and typical use on water supply lines from the harbor. The available details are as follows:

Pressure management

• Regulated/limited outlet pressure: 3.1 bar (45 psi).
• Maximum inlet pressure: 10 bar (145 psi).

The limitation to 3.1 bar is useful to prevent high pressure from the harbor network from being directly transferred to the onboard system and pump.

Connections and configuration

• Inlet: female thread of 3/4″ for garden hose, with detachable stainless steel filter.
• Outlet: male thread of 1/2″ with 90-degree elbow to facilitate installation.

The presence of 90° elbow helps manage the bulk and orientation of the connection, especially in technical spaces where the hose passage requires an immediate bend.

Materials and dimensions

• Material: white plastic.
• Dimensions: 130X130X88 MM.

Codes and references

• Product code: 44411-1045.
• Reference: 0392904030.
• Supplier product code: 0294441110.
• Ex FNI code: 1616851.

These references are useful for catalog checks, reorders, and maintenance replacements.

Typical applications (nautical and onboard plant engineering)

The pressure regulator is indicated in all situations where the onboard system is fed by the external water network and a controlled pressure is desired. Examples of use:

• Connection to the water column in the port to supply the onboard water system.
• Use on supply lines where the network pressure may be variable.
• Installations where it is useful to integrate a detachable filter at the entry point.

It is a component consistent with contexts such as pressure tanks, water lines and distribution systems onboard, when you want to properly manage the interface between the external network and the internal system.

Operational advantages

Without making unverifiable promises, this regulator offers practical advantages related to its function and fitting configuration:

• System protection: pressure reduction helps limit stress on pipes and components when water comes from an external network.
• More constant pressure at the outlet compared to typical variations of the port network, thanks to the limitation to 3.1 bar.
• Facilitated installation thanks to the 90° elbow and the provided threads (3/4" inlet and 1/2" outlet).
• Detachable stainless steel filter at the inlet, useful for routine management and cleaning.
• Clear references (codes and cross reference) for maintenance and replacement.

Usage and installation notes

For correct use in the nautical field, it is advisable to consider some general good practices (without replacing the manufacturer's instructions):

• Placement: install the regulator on the connection between the port water network and the onboard system, respecting the inlet/outlet direction indicated by the fittings.
• Thread control: check the compatibility of the fittings (3/4" female inlet, 1/2" male outlet) with your hose and system.
• Filter management: the detachable filter can be removed for periodic inspection and cleaning, especially if the dock water contains residues.
• Leak check: after connection, check for any leaks and ensure the fittings are properly tightened.
• Use in maintenance: in case of replacement, use the codes (44411-1045 / 0392904030 / 0294441110 / ex 1616851) to identify the correct spare part.

Note: If your system includes additional components (e.g., valves, specific fittings, or additional filtration systems), evaluate integration based on the existing configuration without forcing unsuitable adaptations.
