Nipple Valve S Pump (black hose port) – code: 385311315 – Dometic

Nipple Valve S Pump (black hose holder) Dometic – code 385311315

The Nipple Valve S Pump Dometic (version black hose holder) is a dedicated adapter designed to create a neat and reliable connection within systems with S series vacuum pumps. The component is designed to provide a proper fit between parts, reducing the risk of inaccurate connections and helping to keep the system clean and functional during installations, replacements, or maintenance interventions.

This version is identified by the Dometic code 385311315 and is offered as a spare part/accessory in the nautical and onboard system sector, where the quality of the fitting and attention to assembly details are fundamental for operational continuity.

Features and construction details

The Nipple Valve S Pump is described as a specialist adapter designed to achieve a correct and stable connection. The goal is to facilitate assembly consistent with the architecture of S series vacuum pumps, avoiding improvised solutions or unsuitable adaptations.

Dedicated adapter for neat connections

• Specific component for applications with Dometic S series vacuum pumps.
• Black hose holder: configuration designed for integration into the circuit and for a neat installation.
• Precise coupling: conceived for a correct fit, useful to limit typical problems of connections that are not perfectly aligned.

Seal: important assembly instructions

For this component, Dometic indicates that the use of PTFE tape (Teflon) on the threads is not recommended. The reason is related to the sealing principle of the system: the vacuum seal is achieved through the’integrated O-ring in duckbill valve (duckbill valve). The application of PTFE tape can interfere with the fitting and, according to the manufacturer's instructions, can cause damage to the fitting or the valve.

Practical note: during installation it is therefore advisable to follow the manufacturer's instructions and ensure that the contact surfaces are clean and that the O-ring is properly seated, avoiding non-recommended sealing materials.

Product identification

• Brand: Dometic
• Product code (Supplier product code): 385311315
• SKU: DOM000000045

Typical applications in the nautical field

This adapter is designed for use with S series vacuum pumps and associated generators, as indicated in the manufacturer's description. In an onboard context, it may be among the components used in toilet management systems and lines connected to vacuum pumps, where the correct connection between elements is essential for smooth operation.

When it may be needed

• Replacement of an existing fitting during scheduled maintenance.
• Restoration of a connection after disassembly or interventions on the system.
• Installations where you want to use a dedicated component consistent with the S series.

Operational advantages

In a technical system, a proper fitting is not a detail: it contributes to the overall quality of the installation and ease of management over time. The Nipple Valve S Pump Dometic is designed to provide an adequate connection to the system, with clear instructions on how to achieve the intended seal.

Why choose a dedicated spare part

• Consistent integration with S-series vacuum pumps: reduces the need for suboptimal adaptations.
• Orderly connection: the hose holder allows a practical connection in the circuit.
• Defined assembly instructions: the seal relies on the O-ring integrated in the duckbill valve, avoiding the use of non-recommended sealants.

Usage and installation notes

For a correct result, it is advisable to approach the installation with a “clean” approach: compatible components, orderly surfaces, and compliance with Dometic's instructions. In particular, the note on PTFE tape is relevant because it is often used as a standard solution on threads, but in this case it is not recommended.

Guidelines (based on available instructions)

• Do not use PTFE tape (Teflon) on the threads.
• Ensure that the duckbill valve and its integrated O-ring are in good condition and properly positioned.
• During assembly, avoid forcing and check the alignment of the fitting for a correct coupling.

Important note

The use of PTFE tape, besides not being necessary in this case, can interfere with the intended seal and, according to the manufacturer, can damage the fitting or the duckbill valve. For onboard system interventions, always follow the procedures and recommendations of the system manufacturer.

FAQ – Frequently Asked Questions

What is the Nipple Valve S Pump Dometic for?

It is a specialized adapter designed to create a correct connection in systems with Dometic S series vacuum pumps and associated generators, helping to achieve a proper coupling between components.

Is this component compatible with all S-series vacuum pumps?

The manufacturer's description states that it is designed for use with all vacuum pumps of the S series and associated generators. For special cases, it is advisable to check code 385311315 against the exploded view/spare parts of your system.

Can I use PTFE (Teflon) tape on the threads?

No. Dometic does not recommend the use of PTFE tape: the vacuum seal is guaranteed by the O-ring integrated in the duckbill valve. PTFE can cause damage to the fitting or the valve.

Where does the vacuum seal occur in this system?

The vacuum seal is indicated as entrusted to the O-ring integrated in the duckbill valve, not to the sealant on the threads.

What is the spare part code and how can I identify it?

The Dometic product code (Supplier product code) is 385311315. On the website, it is associated with SKU DOM000000045 and the description “Nipple Valve S Pump (black hose holder)”.
