38 mm Check Valve – code: 29295-0010 – Jabsco

Jabsco 38 mm non-return valve (code 29295-0010)

The Jabsco inline non-return valve with hose connection 38 mm (code 29295-0010) is a component designed for onboard systems where it is necessary to properly manage the suction flow and reduce the risk of backflow. It is a practical solution for direct insertion on existing pipes, especially useful when working on long suction lines or on systems where priming continuity is an important aspect.

In the nautical field, a non-return valve is often used for promote priming and for limit liquid return to undesired areas. This model is suitable for installation online on suction pipe and integrates simply within the circuit without requiring complex structural modifications.

Features and construction details

This valve is of the type In-Line Non-Return Valve (inline non-return valve) and is designed to be inserted directly into the pipe section concerned. The configuration straight facilitates integration on linear paths and helps maintain an orderly pipe layout.

Main data (from product sheet)

• Brand: Jabsco
• Product code (Part Number): 29295-0010
• Type: check valve online
• Tube size: 38 mm (tube ID 1-1/2″)
• Shape: straight
• Material: plastic
• Color: black

Function in the circuit

Installed on the suction tube, the valve works to allow fluid to pass in only one direction and prevent backflow. In typical onboard applications, this helps to keep the liquid column in the line more stable and can be useful to support pump priming and to reduce water return to areas such as bilges.

Recommended onboard applications

The Jabsco 38 mm check valve is suitable for systems where it is useful to prevent fluid from returning along the suction line. Based on available information, it is intended for use with:

• High-capacity bilge pumps (High-Capacity Bilge Pumps)
• Marine toilets with freshwater flush (Freshwater Flush Toilets)

When it can be particularly useful

• Long suction lines, where maintaining priming can be more critical.
• Systems where you want to limit liquid return towards the source or towards undesired areas.
• Maintenance or refitting interventions where you want to add a valve on an existing line, without redesigning the system.

Operational advantages

In an onboard system, choosing a check valve with the correct diameter and installation can simplify circuit management and make the behavior of the suction line more predictable. This Jabsco model, designed for tube size 38 mm, offers a direct solution consistent with typical uses on pumps and marine services.

Strengths

• Inline installation: it fits directly into the suction tube.
• Priming support: useful to help the pump keep the line ready for use, especially on long runs.
• Backflow reduction: helps prevent liquid backflow along the pipe.
• Corrosion-resistant materials: suitable for the nautical context.
• Straight format and configuration: easy integration on linear paths.

Use, installation and notes

The valve is designed to be simply inserted into the suction pipe. To achieve a correct result, it is important to respect the installation direction indicated by the valve (flow direction) and verify that the pipe diameter matches the component size.

Practical indications

• Diameter check: this model is for 38 mm ID pipe. Before purchasing and installing, check the actual size of your piping.
• Positioning: install the valve in the suction section where it is most useful to counteract backflow and support priming, depending on the system configuration.
• Integration on existing lines: it is also suitable for installation on already existing pipes, during maintenance or system upgrades.
• Periodic checks: as with any onboard hydraulic component, it is good practice to periodically check the overall condition of the line and the absence of anomalies.

Note on size variants

The product family is also indicated as available for connections with pipes of 25 o 19 mm. This sheet refers to the 38 mm with code 29295-0010.
