Products Description
Need reliable, leak-proof connections for your compressed air system or pneumatic equipment?
Guanjiang's Pneumatic Connectors are precision-engineered components designed to create secure connections in compressed air systems. Available in push-to-connect, threaded, quick-disconnect, and barbed types, they facilitate rapid, reliable joining of air lines and pneumatic devices. Manufactured from brass, stainless steel, or engineering plastics with precision-machined sealing surfaces, these connectors ensure optimal airflow and pressure maintenance — serving as critical interface points in automated systems, manufacturing equipment, and industrial machinery.
Key Advantages
Precision-engineered sealing mechanisms prevent air leakage. Secure locking systems maintain connection under vibration and pressure cycling.
Quick-connect designs enable rapid installation and disconnection. Tool-free operation reduces maintenance downtime.
Brass, stainless steel, or engineering plastic construction. Corrosion-resistant coatings withstand harsh environments — long service life.
Push-to-connect / Threaded / Quick-disconnect / Barbed types. 1/8" to 2" NPT threads. Compatible with various tubing materials.
0-150 PSI (standard) / Up to 500 PSI (high-pressure versions) — suitable for diverse system requirements.
Locking mechanisms prevent accidental disconnection. Visual indicators for secure connection status.
-20°C ~ 80°C (standard) / High-temp versions available for specialized applications.
Connector Types & Selection Guide
Instant connection — simply insert tubing, no tools required. Ideal for frequent disconnection.
NPT/BSPT tapered threads for permanent connections. Use with PTFE tape or sealant.
Single-action coupling/uncoupling with automatic shut-off. For portable equipment and tool changes.
Cost-effective for flexible hose — secure with hose clamp. Suitable for lower pressure applications.

Frequently Asked Questions
Q1: How do I select the right connector type for my application?
A: Consider pressure rating, tubing type, connection frequency, and environment. For frequent disconnection → push-to-connect or quick-disconnect. For permanent high-pressure lines → threaded (NPT/BSPT). For flexible hose → barbed with clamp. See our selection guide above for detailed recommendations.
Q2: What is the difference between NPT, BSPT, and BSPP threads?
A: NPT (National Pipe Taper) — tapered thread, seals by thread deformation. Common in North America. BSPT (British Standard Pipe Taper) — tapered thread, similar to NPT but different pitch angle. BSPP (British Standard Pipe Parallel) — parallel thread, requires O-ring or gasket for sealing. Always match thread standards between connector and port.
Q3: Can these connectors be used with high-temperature applications?
A: Standard connectors are rated for -20°C to 80°C. For high-temperature applications (up to 200°C), we offer specialized versions with PTFE seals, metal seals, or stainless steel construction. Please specify your operating temperature when ordering.
Q4: How do I prevent air leaks at threaded connections?
A: For tapered threads (NPT/BSPT), apply PTFE tape (2-3 wraps in thread direction) or liquid thread sealant. Do not use PTFE tape on parallel threads (BSPP) — use the supplied O-ring or gasket instead. Tighten to recommended torque — over-tightening can damage threads or seals.
Q5: Are food-grade or medical-grade connectors available?
A: Yes. We offer stainless steel (SS304/316L) connectors with silicone or PTFE seals that meet FDA and USP Class VI requirements for food and medical applications. Please specify your regulatory requirements when ordering.
