The best oil burner supply line is the one that matches the burner model, required tube length, diameter, and connection type. The Beckett 5394 is identified for several Beckett burner models; the Beckett 5628 options are listed at 9.5 inches for AFII or compatible Beckett burners; and the Beckett 5636 options suit buyers comparing shorter lines. Confirm the exact part and dimensions against your burner documentation before ordering. The table summarizes the five listings and their distinguishing details.
| Product | Listed length | Best suited for |
|---|---|---|
| Beckett 5636 6-1/2 inch Oil Line | 6-1/2 inches in product name | Buyers matching a 6-1/2-inch line |
| Beckett 5394 Copper Oil Line | 8 inches | Listed A, AF, AFG, S, SR, and SF burners |
| Beckett 5628 Oil Line | 9-1/2 inches | AFII burner applications |
| Beckett 5636 Oil Nozzle Line | 6 inches | Buyers seeking a 3/16-inch-diameter line |
| 5628 Copper Oil Line | 9.5 inches | Buyers needing female flare fittings |
Beckett 5636 6-1/2-Inch Oil Line
This listing identifies the product as a Beckett 5636 oil line with a 6-1/2-inch length. Its listed country of origin is the United States. The supplied package dimensions are 1 inch by 1 inch by 7 inches; those are package measurements, not a substitute for the line’s stated length.
Best for: Buyers whose burner documentation or existing component calls for a 6-1/2-inch oil line. It was selected because its part number and stated length make it a useful shorter-line option in this comparison.
Check before ordering: The provided details do not specify tube diameter, fitting type, or burner-model compatibility. Do not assume it fits based on the 5636 number alone. Compare the required dimensions and connection with the original part or manufacturer documentation.
Beckett 5394 8-Inch Copper Oil Line
The product name describes the Beckett 5394 as an 8-inch copper oil line for use with A, AF, AFG, S, SR, and SF oil burners. That model list is the clearest selection detail supplied for this item and can help buyers narrow down the search when replacing a line on one of those burner families.
Best for: Owners or service professionals working with a listed A, AF, AFG, S, SR, or SF burner who need an 8-inch line. It was selected for its explicitly stated burner applications and length.
Check before ordering: The supplied product information does not state the line diameter or fitting configuration. Confirm those details with the product listing and burner requirements; a matching model family does not by itself verify every connection or installation dimension.
Beckett 5628 9-1/2-Inch Oil Line
The product name specifies a Beckett 5628 oil line measuring 3/16 inch by 9-1/2 inches and identifies it for an AFII burner. The stated diameter and length make this listing a more specific match than products whose supplied details omit one or both measurements.
Best for: Buyers replacing a line for an AFII burner when the required specification is 3/16 inch by 9-1/2 inches. It was selected because both the named application and dimensions are included in the product title.
Check before ordering: The provided details do not identify the fitting style. Verify the connection type and confirm that the measurement method matches the replacement requirement. Do not treat a similar part number or length as proof of an exact fit.
Beckett 5636 6-Inch Oil Nozzle Line
This listing describes a Beckett 5636 oil nozzle line measuring 6 inches long, with a 3/16-inch diameter. Its features state that the line is made of metal and give an outside diameter of 0.1875 inches and an inside diameter of 3/16 inch. The listed dimensions provide a useful comparison point for a replacement with the same specified size.
Best for: Buyers who need a short 6-inch line and can verify that the stated diameter matches their burner assembly. It was selected as a compact alternative to the other Beckett listings, including the separately listed 6-1/2-inch 5636.
Check before ordering: This listing’s stated 6-inch length differs from the other 5636 product title’s 6-1/2-inch length. Treat them as separate listings and confirm the required measurement rather than assuming the products are identical.
5628 9.5-Inch Copper Oil Line
This 5628 listing describes a 9.5-inch copper oil line assembly with 3/16-inch female flare tube fittings. Its supplied details say it is engineered for Beckett oil burners requiring a 9-1/2-inch fuel-routing line. It is the only product in this group whose provided features explicitly identify female flare fittings.
Best for: Buyers who need a 9.5-inch line and have confirmed that their application calls for 3/16-inch female flare tube fittings. It was selected to provide a connection-specific option alongside the Beckett 5628 listing that names an AFII burner.
Check before ordering: The provided description claims compatibility with Beckett burners that require this routing line, but it does not name specific burner models. Confirm the exact burner requirement and connection before purchase.
Buying Guide: How To Choose An Oil Burner Supply Line
Which line length do you need?
Start with the replacement specification or the burner manufacturer’s documentation. The five listings cover stated lengths from 6 inches to 9.5 inches, including an 8-inch option. Measure the existing part only if you can do so safely and accurately, and check whether the documented length refers to the entire line or a particular section. A small length difference can matter when a part must route through a defined burner assembly.
Pay special attention to the two 5636 listings. One product name says 6-1/2 inches; the other says 6 inches. They should not be treated as interchangeable just because they share a part number. If the required length is unclear, identify the burner and consult its service documentation or a qualified technician before ordering.
How should you verify burner compatibility?
Match the oil line to the exact burner model whenever possible. The Beckett 5394 listing names A, AF, AFG, S, SR, and SF burners. The Beckett 5628 title names the AFII burner. Another 5628 listing describes use with Beckett burners requiring a 9-1/2-inch line, without naming individual models. Use these statements as selection clues, not as a substitute for checking the manufacturer’s part requirements.
When the product data does not name your burner model, do not infer compatibility from appearance, brand, or a similar part number. Verify the part number and fit requirements in the burner manual, parts list, or with a service professional. This is especially important if the old line has been modified or is not clearly identifiable.
Why do diameter and fittings matter?
A line can have the correct length and still be unsuitable if its diameter or connection differs from the required assembly. The 6-inch Beckett 5636 listing states a 3/16-inch diameter, and the 9.5-inch 5628 listing specifies 3/16-inch female flare tube fittings. The other supplied descriptions do not provide all of these details. Check the full product listing and compare it with the required connection before buying.
Do not assume that “3/16 inch” describes every important dimension or fitting. A tube’s diameter and a fitting’s type are separate specifications. If the product information is incomplete, seek clarification rather than relying on a photograph or a general description.
Should you choose copper or metal?
The Beckett 5394 and one 5628 listing identify copper in their names or features. The 6-inch Beckett 5636 listing describes its construction as metal but does not specify a more precise material in the supplied details. Material alone does not determine fit. Prioritize the burner’s specified part, dimensions, routing, and connections before comparing material descriptions.
What should you check before installation?
Oil burner service involves fuel and combustion equipment. If you are not trained to work on the burner, have a qualified heating professional identify and install the replacement. Follow the appliance manufacturer’s service instructions, and do not operate equipment if a fuel connection appears damaged, loose, or leaking.
- Confirm the burner model and specified replacement part.
- Compare line length, diameter, and fitting type with the required specifications.
- Check that the selected listing’s details are complete enough to establish the match.
- Do not force a line or connection that does not fit as specified.
- Have the installation and burner operation checked by a qualified professional when needed.
How do the five options compare?
For a named set of Beckett burner families, the 8-inch 5394 is the most directly specified option in this group. For an AFII application, the 9-1/2-inch 5628 title is the clearest model-specific listing. For a 9.5-inch line with female flare fittings, the other 5628 provides the most connection detail. The two 5636 listings are shorter options, but their stated lengths differ and should be checked carefully.
