What is a Male Elbow 407 Brass Fitting?

The male elbow 407 brass fitting is a specialized plumbing component designed for directional pipe connections. This fitting features external threads that screw into female-threaded pipes or fixtures. The 407 designation refers to specific dimensional standards in industrial piping systems.

Brass construction offers superior corrosion resistance compared to steel alternatives. The material withstands high temperatures and pressures in demanding applications.

Key Specifications and Dimensions

Standard Measurements

• Thread sizes: 1/8″ to 4″ NPT available
• Elbow angles: 90-degree standard, custom angles possible
• Wall thickness: Varies by size specification
• Working pressure: Up to 150 PSI at room temperature

Material Properties

Brass 407 alloy contains approximately 60% copper and 40% zinc. This composition provides excellent machinability during manufacturing. The material resists dezincification in most water conditions.

Temperature ratings extend from -65°F to 250°F (-54°C to 121°C). Higher temperature applications require special consideration.

Proceso de fabricación

Precision Machining

Factory production begins with brass bar stock selection. CNC machining creates precise thread profiles and internal passages. Quality control measures ensure dimensional accuracy within ±0.002″ tolerances.

Hot forging processes shape the elbow configuration. This method maintains grain structure integrity throughout the fitting body.

Surface Finishing

Standard finishes include natural brass, nickel plating, and chrome plating. Custom finishes are available for specific project requirements.

Thread cutting follows ANSI B1.20.1 standards for NPT connections. Proper thread engagement ensures leak-free installations.

Applications and Industries

Fontanería comercial

Male elbow fittings connect supply lines in commercial buildings. They’re essential for water distribution systems and fixture installations. The brass material suits potable water applications.

Industrial Systems

Process piping utilizes these fittings for chemical and petroleum applications. Brass resists many corrosive substances encountered in industrial environments.

HVAC Applications

Heating and cooling systems require reliable connections at directional changes. The 407 brass fitting handles thermal expansion without failure.

Custom Manufacturing Options

Tailored Specifications

Factory orders accommodate non-standard dimensions and configurations. Custom thread pitches serve specialized equipment requirements. Modified angles beyond standard 90-degrees are possible.

Volume Production

Minimum order quantities vary based on complexity. Standard sizes require lower minimums than custom specifications. Lead times range from 2-8 weeks depending on requirements.

Quality Certifications

Manufacturing follows ISO 9001 quality standards. Material certificates verify brass composition and properties. Pressure testing validates performance ratings.

Installation Best Practices

Thread Preparation

Clean threads thoroughly before assembly. Apply appropriate thread sealant or tape. Hand-tighten first, then use wrenches for final positioning.

Torque Specifications

Avoid over-tightening which can damage threads or crack the fitting body. Follow manufacturer torque recommendations for each size.

System Compatibility

Verify compatibility with existing pipe materials. Dissimilar metals may cause galvanic corrosion in certain environments.

Mantenimiento y longevidad

Vida útil

Properly installed brass fittings last 20-50 years in typical applications. Regular inspection identifies wear or corrosion early. Replacement is recommended when threads show significant wear.

Cleaning Procedures

Periodic cleaning maintains appearance and function. Mild detergents remove surface contamination. Avoid abrasive cleaners that damage protective finishes.

Cost Considerations

Initial Investment

Brass fittings cost more than plastic alternatives initially. However, longer service life provides better long-term value. Reduced maintenance needs offset higher material costs.

Factory Direct Pricing

Ordering directly from manufacturers eliminates distributor markups. Volume discounts apply to larger quantities. Custom orders may include tooling charges.

Quality Assurance Standards

Testing Procedures

Each fitting undergoes pressure testing during manufacturing. Thread gauging verifies dimensional accuracy. Visual inspection catches surface defects.

Compliance Certifications

Products meet ASTM B584 standards for brass castings. NSF certification ensures potable water safety. UL listings cover specific applications.
