Precision Brass Hex Bushings Manufacturer
Our brass hex bushings are engineered to reduce the thread size of female pipe connections, creating secure, leak-resistant joints. Machined from superior forged brass, these fittings provide the mechanical strength, corrosion resistance, and precise dimensional tolerances essential for plumbing, water distribution, compressed air, gas, irrigation, and complex industrial piping networks.
We supply directly to OEM manufacturers, plumbing distributors, hardware wholesalers, and industrial suppliers requiring consistent product quality and stable inventory.
Technical Performance & Buyer Benefits
1. CNC Machined Threads for Reliable Sealing
Every thread is CNC-machined according to international standards (BSP, BSPT, NPT, G) to ensure precise engagement.
- Easier Assembly: Smooth thread entry reduces manual labor and installation time.
- Zero-Failure Installation: Strict thread tolerance control prevents cross-threading and rejection rates.
- Leak-Proof Integrity: Standard-compliant profiles eliminate micro-gaps, ensuring reliable seals when used with sealants.
- Reduced Warranty Risks: Reliable connections minimize after-sales failures, protecting your brand reputation.
2. Forged Brass Body for High Mechanical Strength
Unlike cast fittings prone to internal porosity and sand holes, our fittings are hot-forged. This process creates a dense grain structure, resulting in:
- Superior Pressure Resistance: Increased durability under high-pressure conditions.
- High Torque Tolerance: The body resists cracking during heavy-duty tightening.
- Longevity: Ensures a long service life and supports repeated assembly cycles.
3. Material-Specific Corrosion Resistance
Brass naturally resists corrosion in water, compressed air, and non-aggressive fluids.
- Versatile Applications: Ideal for potable water (with lead-free brass), HVAC systems, pneumatic pipelines, agricultural irrigation, and marine environments.
- Maintenance Efficiency: Superior to carbon steel, our brass prevents rust formation, drastically reducing long-term maintenance costs.
4. Hexagonal Design for Efficient Wrenching
The machined hex body provides a flat, solid gripping surface that:
- Prevents Slippage: Protects the fitting surface from damage during installation.
- Optimizes Space: Allows for higher tightening torque even in restricted, tight spaces.
- Speeds Up Production: Ideal for high-speed assembly lines and professional field contractors.
Pressure & Temperature Ratings
When installed with proper sealing materials (e.g., PTFE tape), our fittings operate reliably within the following parameters:
Working Pressure: Up to 16–25 bar (230–360 psi), contingent on size, wall thickness, and industry standards.
Temperature Stability: Engineered for consistent performance across hot and cold water cycles, hydronic heating, and compressed air systems without becoming brittle.

FAQ
Q: What is a Brass Hex Bushing?
A: It is a reducing fitting featuring external male threads and smaller internal female threads, used to adapt larger female pipe connections to smaller male connections.
Q: Which brass grades do you use for drinking water?
A: For markets requiring strict compliance (e.g., USA, parts of Europe), we utilize certified lead-free brass alloys meeting NSF/ANSI 61 and RoHS requirements.
Q: Can you manufacture from our samples or 3D files?
A: Absolutely. Our engineering team can analyze your physical samples or digital files (STEP/IGS) to create precise production drawings.
Q: Do you offer surface plating?
A: Yes. We offer nickel plating (enhanced corrosion resistance) and chrome plating (aesthetic finishes), alongside natural acid-washed brass.
