When a separator needs replacement, a bundle photo can make it hard to tell which parts you are about to order. Start by deciding whether your service provider wants a specific replacement component or needs to review a complete hose set. Then ask the seller to break out the package contents and identify each relevant part.
Compare the package descriptions
The TRIMIX Small Oil Water Separator listing describes a package containing one separator. The TRIMIX Refill Hose & Oil Water Separator listing lists one refill hose and one blue separator. The difference between those package descriptions is clear. Whether the separator in the bundle has the same part number and specifications as the separately listed item still needs confirmation.
Ask for each component’s model or part number and the written specifications for its connections and ratings. Include the exact compressor or filling equipment and the receiving assembly in your request. An answer that describes only the outside color or shape gives a service provider too little information to assess a match.
Keep three decisions separate in the quote
- Package scope. Is the seller quoting a separator, a hose and separator set, or separately identified parts?
- Fit and ratings. Which equipment and connections does each part’s documentation identify, and who will confirm that the stated ratings apply to the complete proposed arrangement?
- Air quality. What evidence will the qualified fill provider use to establish that the equipment and process produce suitable breathing air?
DAN’s breathing-gas contamination guidance explains why contamination matters for divers and discusses controls that apply to the source of the breathing gas. A catalogue name for a component does not establish the air quality of a filling arrangement. Bring the requested specifications and the actual equipment details to a qualified provider before making that decision.
Leave unidentified items open
Keep the component number, ratings, connections and package quantities on separate lines. If two quotations omit one of those fields, ask for the missing information before comparing price or treating the items as interchangeable. Retain the written confirmation for later replacements.
Ask TRIMIX for the hose and separator part details. Include the equipment identifiers and say whether you are looking for one replacement component or want the whole bundle assessed.
