Pneumatics & Automation

Building reliable pneumatics and automation systems requires precision-engineered components that can withstand high-pressure environments. Whether you are designing a robotic air gripper, replacing a tie-rod cylinder in a factory line, or upgrading your air compressor's FRL unit, we have the exact industrial-grade parts you need. Backed by 20 years of engineering supply experience in Sham Shui Po, our technical team provides on-site component matching and thread compatibility checks to ensure your pneumatic circuits operate leak-free.

Industrial Pneumatic Components & Specifications

Selecting the correct pneumatic parts is critical for maintaining consistent air pressure and preventing catastrophic blow-outs. Here is a technical breakdown of our core automation inventory:

Component Category Key Technical Features Best Use Case
Push-to-Connect Fittings Supports 4mm - 12mm OD tubing, quick-release collars. Rapid routing and splitting of PU/PE air lines in automated machinery.
Pneumatic Cylinders & Actuators Tie-rod, rotary, and angular gripper designs. Linear pushing/pulling, robotic gripping, and automated sorting lines.
Air Preparation (FRL Units) Filter, Regulator, and Lubricator integration. Removing moisture from compressor air and regulating output pressure.
Control Valves & Silencers Manual hand valves, speed controllers, sintered brass mufflers. Regulating piston speed and reducing high-decibel exhaust noise.

Important Note (Pressure & Thread Limitations): Standard push-to-connect polyurethane (PU) fittings are rated for a maximum working pressure of 1.0 MPa (approx. 145 PSI). They must never be used for high-pressure hydraulic (oil) systems or volatile gas lines. Additionally, always verify your metal thread types—forcing a BSPT (British Standard Pipe Taper) fitting into an NPT (National Pipe Taper) port will result in stripped threads and dangerous air leaks.

Frequently Asked Questions (FAQ)

Q: Why is my pneumatic cylinder moving inconsistently or jerking during its stroke?
A: Cylinder jerking is usually caused by a lack of lubrication or improper airflow regulation. Ensure your FRL unit is dispensing the correct amount of pneumatic oil. More importantly, you should install a Pneumatic Speed Controller Valve on the cylinder's exhaust port to create back-pressure, which smooths out the piston's movement.

Q: How do I choose the right outer diameter (OD) for my pneumatic tubing?
A: The tubing OD must perfectly match the push-to-connect fitting. Common metric sizes are 4mm, 6mm, 8mm, and 10mm. Using imperial tubing (like 1/4") in a 6mm metric fitting will cause immediate blow-outs under pressure. Bring your existing tube or fitting to our physical store, and our technicians will measure it with digital calipers for an exact match.
