Pneumatic hardware fittings are essential components used to connect pipes, tubes, and actuators in compressed air systems. These fittings play a vital role in maintaining efficient airflow, preventing leakage, and enabling quick disassembly or reconfiguration. They are widely used in automated machinery, manufacturing lines, robotics, and other industrial settings requiring precision control and clean energy.
Leak-Proof Sealing: Designed for high pressure and vacuum-tight connections.
Quick Installation: Push-to-connect and threaded types for fast assembly.
Corrosion Resistance: Suitable for demanding environments with chemicals or humidity.
High Durability: Long service life with minimal maintenance.
Compatibility: Fit a variety of tube sizes, thread standards, and operating pressures.
| Material | Properties | Recommended Applications |
|---|---|---|
| Brass | Excellent corrosion resistance, machinability | General industrial, air compressors |
| Stainless Steel (304/316) | High strength, anti-rust, hygienic | Food & beverage, pharmaceuticals, outdoor use |
| Aluminum | Lightweight, good heat resistance | Robotics, packaging machinery |
| Plastic (PBT/PA) | Lightweight, cost-effective, chemical resistant | Low-pressure systems, lab environments |
| Surface Treatment | Purpose | Benefits |
|---|---|---|
| Nickel Plating | Anti-corrosion and aesthetic finish | Ideal for humid or corrosive environments |
| Zinc Plating | Budget protection against rust | Used in dry indoor industrial setups |
| Anodizing (Aluminum) | Hardens surface and adds color | Improves durability and identification |
| Passivation (Stainless) | Removes surface impurities | Enhances corrosion resistance and cleanliness |
| Type | Description | Typical Use Case |
|---|---|---|
| Straight Fittings | Direct connection between two points | Standard flow direction connections |
| Elbow Fittings | 90° direction change in piping | Space-constrained installations |
| Tee Fittings | Split airflow into two directions | Distributing air from one source |
| Cross Fittings | Connects four tubes or hoses | Complex pneumatic networks |
| Bulkhead Fittings | Mounts through panels or walls | Enclosures or machinery housings |
| Reducer Fittings | Connects tubes of different diameters | Adapting to system changes |
| Model No. | Thread Type | Tube Outer Dia. | Material | Surface Treatment | Operating Pressure |
|---|---|---|---|---|---|
| PHF-01 | BSPT 1/4” | Ø6mm | Brass | Nickel Plated | 0–1.0 MPa |
| PHF-02 | NPT 3/8” | Ø8mm | Stainless 304 | Passivated | 0–1.2 MPa |
| PHF-03 | BSPT 1/2” | Ø10mm | PBT Plastic | None | 0–0.8 MPa |
| PHF-04 | BSPT 1/4” | Ø12mm | Aluminum | Anodized | 0–1.0 MPa |
Pneumatic hardware fittings are used across various industries and applications:
Automated Assembly Lines
Textile Machinery
Food and Beverage Packaging
Medical and Laboratory Equipment
Electronics and Semiconductor Manufacturing
Woodworking and Furniture Production
Their versatility and ease of use make them the standard choice for systems requiring reliability, speed, and cleanliness.
Proper handling of fittings extends their operational life and ensures safe usage:
Use appropriate sealing tape or paste for threaded fittings.
Avoid excessive torque to prevent thread damage.
Periodically inspect for leakage, wear, and corrosion.
Clean and re-seal connections during reinstallation.
Store unused fittings in dry, dust-free environments.
Before purchase, consider:
Tube Size Compatibility
Thread Type (BSPT, NPT, Metric)
Working Pressure & Temperature Range
Material Compatibility with Media
Corrosion Resistance for Environment
Consult with technical experts to match fitting type and material to your working conditions.
Q1: Can pneumatic fittings be reused?
A1: Yes, but only if the fitting is not damaged or deformed. Always inspect O-rings and sealing threads before reuse.
Q2: What is the difference between BSPT and NPT threads?
A2: BSPT (British) and NPT (American) threads are not interchangeable due to angle and pitch differences. Always match the thread type to your system standard.
Q3: Are these fittings suitable for vacuum systems?
A3: Many fittings support vacuum applications. Confirm with pressure specifications in product details.
