Pneumatic hardware fittings are small yet crucial components used in air-powered systems. Their main purpose is to connect, redirect, or seal tubing and equipment in pneumatic circuits — ensuring efficient, leak-free air delivery. Choosing the right fittings plays a key role in system performance, durability, and safety.
Our company specializes in high-precision pneumatic fittings that are suitable for a wide range of industries, including:
🚗 Automotive and maintenance
🏭 Industrial automation
📦 Packaging and food processing
🤖 Robotics and assembly lines
🔬 Laboratory and testing equipment
| Fitting Type | Description | Typical Use |
|---|---|---|
| Straight Connectors | Direct connection between two tubes or ports | Air compressors, main pipelines |
| Elbow Connectors | Allows 90° or angled redirection of airflow | Compact machinery layouts |
| Tee & Y Fittings | Split or combine airflow paths | Multi-tool operations, air cylinder networks |
| Quick-Release Couplers | Fast and tool-free connection/disconnection | Portable air tools, repair garages |
| Threaded Adapters | Connect different thread types or sizes | NPT–BSP conversions, system upgrades |
| Swivel Joints | Allow rotation under air pressure | Dynamic hoses, robotic arms |
To ensure resistance to wear, corrosion, and extreme working conditions, our pneumatic fittings come with a variety of professional surface treatments:
| Surface Treatment | Description | Advantages | Typical Materials Applied On |
|---|---|---|---|
| Nickel Plating | Thin layer of nickel coating | Corrosion resistance, shiny finish | Brass, steel |
| Chrome Plating | Thick, polished chrome coating | High hardness, wear-resistant, mirror-like | Brass, stainless |
| Anodizing | Electrochemical process for aluminum | Color options, surface hardness | Aluminum alloy |
| Passivation | Acid treatment to remove contaminants | Improves stainless steel’s corrosion resistance | Stainless steel |
| Zinc Plating | Electroplated zinc layer | Low-cost anti-rust coating | Steel |
🛡️ These finishes not only enhance the appearance but also improve mechanical and chemical resistance in demanding industrial environments.
We offer fittings made from:
Brass – Affordable, anti-rust, suitable for dry air
Stainless Steel (304/316) – Hygienic, anti-corrosive, high strength
Aluminum Alloy – Lightweight and cost-effective
PBT / PA Plastic – Ideal for low-pressure, temporary, or lightweight systems
Need food-grade or chemical-grade materials? We support FDA-compliant stainless steel and ROHS-certified surface finishes.

Most of our push-in fittings support flexible polyurethane (PU), nylon (PA), or polyethylene (PE) tubing.
Ensure tubing is cut squarely for push-in fittings
Use PTFE tape on male threads to improve sealing
Don’t overtighten metal fittings, especially on soft metals
Use locknuts or collars in high-vibration environments
Inspect O-rings periodically for wear and tear
