K&S 8139 Round Brass Tube 1/2 in OD × 12 in – 1 Piece: Scale, Subject & Display Guide
This page is devoted to K&S 8139 Round Brass Tube 1/2 in OD × 12 in – 1 Piece, the exact model building materials sold under the K&S Precision Metals record. The goal is practical identification: what the listing confirms, what remains unverified, and what a buyer or builder should compare before using the item.
How this release is identified
- Exact product: K&S 8139 Round Brass Tube 1/2 in OD × 12 in – 1 Piece
- Brand or vendor: K&S Precision Metals
- Product type: Model Building Materials
- SKU or catalog key: K+S8139
- Scale stated in the record: 1/2
- Variants reviewed: 1
- Product images indexed: 2
The recorded price at verification was $4.99 before shipping and tax. At least one variant was orderable when the record was checked.
The scale marker 1/2 is part of the exact identity and should be matched before purchase. The working catalog key is K+S8139. That key should travel with the saved URL and product image so a later comparison does not collapse this item into another model building materials listing.
What the current listing actually confirms
The product page identifies the item this way: “K&S 8139 Round Brass Tube supplies brass tubing for model building, miniature structures, crafts and fabrication projects. Each tube is 1/2 inch outside diameter, with a 0.014-inch wall and a 12-inch length. Material: brass. Profile: round. Outside dimension: 1/2 inch. Wall thickness: 0.014 inch. Length: 12 inches per tube. Package quantity: 1 tube. Manufacturer item 8139. Cut and fit the tubing for your project using suitable metalworking tools. Tools, glue and other project materials are sold separately.” That excerpt anchors the guide, while the gallery, SKU and selected variant provide the remaining evidence needed for an exact match.
How to evaluate this product type
Use a collector-style inspection on K&S 8139 Round Brass Tube 1/2 in OD × 12 in – 1 Piece: confirm the casting silhouette, visible finish, graphic layout, wheel and tire combination, base details, interior color and package state shown. These details create the release identity. Price or brand recognition alone cannot establish that another car is equivalent.
If the item will be customized, photograph and record its starting condition first. If it will remain original, store it so metal edges, wheels and printed surfaces do not rub adjacent models. The decision depends on the exact item represented by K+S8139, not on a generic diecast workflow.
The details to verify next
Similar diecast products often differ in small, high-value details. Review the wheel spokes, tire profile, base color, glazing, interior, license or race markings and package code. The aim is not to assign a grade from a distance but to confirm that the delivered item matches the release purchased.
Display and handling should follow the format: loose models need nonabrasive separation, packages need edge and blister protection, and project cars need a documented baseline before disassembly.
Why the exact photo set matters
The gallery contains 2 indexed product images. Compare label text, package shape, visible contents, finish and any small identifying marks with the delivered item. A context image can show tools or related products that are not included, so the written record and selected option still control package contents.

Cataloging and project notes
After purchase, store the acquisition date, price, seller, SKU K+S8139, selected option and one clear image with the project or collection record. Add notes about fit, assembly, condition or performance only after they are observed on this exact item.
This separates verified ownership evidence from later opinion and makes a replacement or repeat purchase much easier.
Gift considerations
Gift buyers should match K+S8139 to a known collection, project or preference. If size, scale, interface or exact version is uncertain, preserve the receipt and avoid opening fit-sensitive packaging.
Final identity questions
What is the safest comparison key?
Start with K+S8139, then verify the complete title and exact image. That sequence avoids most near-match errors.
Should availability wording be treated as permanent?
No. Inventory and supplier status can change after verification.
What does this guide intentionally avoid?
It avoids invented dimensions, unsupported rarity claims and compatibility assumptions not established by the product record.
Bottom line: K&S 8139 Round Brass Tube 1/2 in OD × 12 in – 1 Piece is a specific model building materials, not a stand-in for the whole category. Match K+S8139, review the images, resolve unconfirmed fit or compatibility points, and retain the product record after purchase.

Verification worksheet for this listing
Use K+S8139 as the checkpoint for K&S 8139 Round Brass Tube 1/2 in OD × 12 in – 1 Piece. Confirm the vendor name K&S Precision Metals, the product type Model Building Materials, the selected variant and the photographed item before checkout. If a required size, scale, material, interface or included component is absent from the live record, write it down as unresolved and obtain the answer from the current instructions or manufacturer source.
After delivery, add a dated photograph and a brief result note. A builder can record fit, materials and finishing choices; a collector can record package and item condition; a user can record compatibility and care. Those details make the record genuinely product-specific while preventing a later observation from being confused with a factory specification.
