Industrial Brass High-Pressure Valve Assembly (Non-Gold Imitation)
Mechanical Plumbing Hardware / Industrial Fitting · Yellow Brass Alloy. The color is derived from the copper-zinc ratio rather than precious metal content.
Purity: 0K / 0% Gold Content. This is a base metal alloy consisting of copper and zinc (Brass). It is not solid gold, gold-plated, or gold-filled.

Purity
0K / 0% Gold Content. This is a base metal alloy consisting of copper and zinc (Brass). It is not solid gold, gold-plated, or gold-filled.
Gold Type
Yellow Brass Alloy. The color is derived from the copper-zinc ratio rather than precious metal content.
Weight
Estimated 250 - 450 grams. As a dense industrial fitting, it is heavy, but significantly less dense than an equivalent gold object.
Description
An industrial brass valve head situated atop a pressurized cylinder or tank. While the color mimics low-karat gold, the structural threads, hexagonal wrench flats, and spring-loaded center pin identify it as a functional gas or liquid regulator component.
Key Features
Machined threading, hexagonal flats for tool grip, internal pressure pin, and circular lathe finishing marks typical of mass-produced hardware.
Color & Finish
Dull yellow with a brassy, greenish-gold hue. The finish shows industrial machining (lathe marks), surface oxidation (patina), and mechanical abrasions.
Hallmarks & Stamps
None visible in the image. Typically would contain manufacture batch numbers or PSI ratings rather than precious metal hallmarks (no 14K, 18K, or 750 stamps).
Dimensions Estimate
Height: Approximately 3-4 inches; Diameter of threaded section: Approximately 1 inch (standard NPT or similar threading).
Gemstones & Inlays
None. The item is purely functional and composed of threaded metal and internal mechanical seals.
Clasp & Closure
Mechanical threads and a pressure-release valve pin. This is not a jewelry closure but a mechanical sealing interface.
Chain & Links
N/A. The item features a hexagonal 'nut' base for wrench application and cylindrical threading for plumbing connections.
Craftsmanship Details
Precision lathe machining and threading. Industrial-grade assembly designed for high-pressure durability rather than artistic beauty.
Authentication Indicators
Red Flags for Gold: Mechanical threading, greenish oxidation/tarnish, visible tool marks, and a lack of hallmarks. The color is 'brassy' rather than the rich warmth of true gold.
Origin & Maker
Likely a specialized industrial manufacturer of gas or fluid handling equipment (e.g., Parker, Swagelok, or generic hardware).
Era & Period
Contemporary Industrial (Late 20th - Early 21st Century).
Age Estimate
Unknown, likely 5-20 years old based on the oxidation and surface wear patterns visible on the brass.
Cultural Significance
Represents modern industrial engineering and fluid dynamics rather than aesthetic or monetary status in the jewelry world.
Condition Notes
Good - Industrial Grade. Shows signs of field use including scratches, minor surface corrosion, and edge wear on the threads. This would be considered 'Scrap' in a precious metal context.
Value Estimate
Melt value of scrap brass (Approx. $2.00 - $5.00 USD per pound). No precious metal value.
Care & Maintenance
Clean with brass polish (like Brasso) for shine. For functional use, ensure threads are clean of debris and use thread-seal tape (PTFE) if applicable.

Interesting Facts
Brass is often referred to as 'Fool's Gold' in the context of hardware/scrap because its weight and color can occasionally deceive the untrained eye under certain lighting.
