The Brass 1/4″ NPTF x 3/8″ Hose Barb is a specialized pipe fitting designed for secure and leak-free hose connections in fluid and air transfer systems. This fitting consists of a National Pipe Taper Fuel (NPTF) male thread on one end and a 3/8″ hose barb on the other, allowing easy and secure attachment of flexible tubing without additional clamps. Made from high-quality Brass, it offers superior strength, corrosion resistance, and excellent thermal conductivity, making it ideal for high-pressure applications.
Material Grades
Our Brass Hose Barbs are manufactured using the following high-grade Brass alloys:
| Material | Standard | Composition | Properties |
|---|---|---|---|
| Brass C36000 (Free-Cutting Brass) | ASTM B16 | 60% Copper, 36% Zinc, 3% Lead | Excellent machinability, high strength |
| Brass C37700 (Forging Brass) | ASTM B283 | 59% Copper, 39% Zinc, 2% Lead | Good corrosion resistance, suitable for forging |
| Dezincification Resistant Brass (DZR Brass – CW602N) | BS EN 12164 | 63% Copper, 35% Zinc, <1% Pb, As | High resistance to corrosion in water systems |
Manufacturing Process
Our Brass Hose Barbs are manufactured using precision machining techniques to ensure tight tolerances, superior surface finish, and leak-proof performance. The production process includes:
- Raw Material Selection: High-quality Brass rods and bars are sourced according to ASTM, DIN, and IS standards.
- CNC Machining: High-precision CNC lathes and multi-spindle automatic machines ensure exact dimensions and tight tolerances.
- Threading: NPTF threads are cut using thread rolling and precision tapping machines to meet ANSI B1.20.3 standards.
- Barb Formation: The 3/8″ hose barb is precisely machined to ensure a secure grip and leak-free fit for flexible tubing.
- Deburring & Polishing: Surface finishing techniques such as vibratory finishing, sandblasting, and ultrasonic cleaning enhance the final product.
- Plating & Coating: Optional nickel or chrome plating can be applied for additional corrosion resistance and aesthetics.
Typical Applications
The Brass 1/4″ NPTF x 3/8″ Hose Barb is widely used in various industries:
