K&S 8140 Round Brass Tube – 17/32 Inch OD x 12 Inch, One Piece: Scale, Subject & Display Guide

The product behind this guide is K&S 8140 Round Brass Tube – 17/32 Inch OD x 12 Inch, One Piece. Because similar model building material products can share brand names or photographs, the analysis below keeps the K&S Precision Metals title, SKU and live image set tied together as one record.
Matching the exact listing
- Exact product: K&S 8140 Round Brass Tube – 17/32 Inch OD x 12 Inch, One Piece
- Brand or vendor: K&S Precision Metals
- Product type: Model Building Material
- SKU or catalog key: K+S8140
- Variants reviewed: 1
- Product images indexed: 1
The recorded price at verification was $5.19 before shipping and tax. At least one variant was orderable when the record was checked.
A correct match requires more than recognizing the brand. For this item, the safest match uses the complete title, vendor, SKU, product type and image together. None of those identifiers should be replaced by a broad category assumption. The SKU K+S8140 provides the most efficient cross-check when another listing uses slightly different punctuation or wording.
The verified description in context
The source description says: “K&S 8140 is a round brass tube for model building and other fabrication projects. This package contains one 12-inch length with 17/32-inch outside diameter and 0.014-inch wall thickness. Reference:8140 Material:Brass Outside diameter:17/32 inch Wall thickness:0.014 inch Length:12 inches Quantity:One tube” This is useful evidence, but it is not expanded beyond what the listing supports. Missing dimensions, materials, compatibility claims or package contents remain open questions.
What matters for this kind of product
For a diecast or scale collectible, the subject name alone is insufficient. Compare body casting, finish, graphics, wheel design, interior, base markings and packaging format. On K&S 8140 Round Brass Tube – 17/32 Inch OD x 12 Inch, One Piece, the exact photo set and SKU K+S8140 are the reference pair; a model with the same vehicle name but a different wheel, road number or package is a different release.
Condition language must also match the format. A loose item is judged from the photographed surfaces and axles, while a packaged item adds card, blister, box and seal condition. A finished custom should be assessed for workmanship and disclosed modifications; a build kit should be assessed for included parts and fitment rather than as a completed collectible.
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.
Image-by-image verification
Review all 1 available image in sequence rather than judging the item from the first thumbnail. Front, side, reverse, package and detail views answer different questions. The record is strongest when those views agree with the title and SKU K+S8140.
Before committing the item to a project
- Match the full title and K+S8140.
- Confirm the selected variant and displayed quantity.
- Review the exact image set for the distinguishing details named above.
- Resolve every missing fit, scale, material or compatibility point from current instructions.
- Check live price and availability immediately before ordering.

Preserving the identity trail
After purchase, store the acquisition date, price, seller, SKU K+S8140, 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
For gifting, the product image can verify the visual subject while the SKU K+S8140 verifies the release. Both checks matter when the recipient collects small variations.
Final identity questions
What identifies this exact product?
The complete title, K+S8140, vendor K&S Precision Metals, product type Model Building Material and photographed item form the identity. None should be replaced by a generic category label.
What is still unconfirmed?
Any dimension, material, accessory, compatibility claim or package component absent from the listing remains unconfirmed until the current instructions or manufacturer record supplies it.
Where should the purchase decision be finalized?
Use the live product page linked below for the current option, price and availability.
Final check: the correct choice is the item whose title, SKU K+S8140, image and variant state agree with the project or collection need. Where one of those elements does not match, continue comparing before ordering.

Verification worksheet for this listing
Use K+S8140 as the checkpoint for K&S 8140 Round Brass Tube – 17/32 Inch OD x 12 Inch, One Piece. Confirm the vendor name K&S Precision Metals, the product type Model Building Material, 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.
