Sinoextrud: Your Air Cylinder Tubing Manufacturer
Air cylinder tubing is a precision-engineered aluminium profile used in the manufacture of pneumatic cylinders. It offers high straightness, excellent dimensional tolerance, and ultra-smooth inner bore surfaces for efficient air sealing and piston movement.
Manufactured from 6063-T5 alloy, the tubing combines light weight with structural strength and corrosion resistance. The anodized finish enhances its wear performance, making it ideal for industrial automation, robotics, and machinery applications.
Surface finishes such as hard anodizing and clear anodizing provide protection against abrasion, oxidation, and chemical attack, extending the lifespan of cylinders in harsh environments.
We offer full custom processing services, including CNC cutting, inner honing, drilling, and polishing to meet exact engineering needs. Tubes can be delivered ready for assembly, reducing production time.
Trusted by global OEMs and cylinder manufacturers, we provide reliable air cylinder tubing solutions with ISO-compliant quality, flexible production, and responsive service for your pneumatic system supply chain.
