Outer cylinder tube is the primary structural housing in gas lift cylinders that contains internal components and withstands operational pressures.
The outer cylinder tube is a precision-engineered cylindrical component that serves as the main pressure vessel in gas lift cylinder assemblies. It provides structural integrity, contains the piston rod and internal seals, and withstands both static and dynamic loads during compression and extension cycles. This component ensures proper alignment of internal parts while maintaining pressure integrity throughout the service life.

Internal diameter tolerance (±0.025 mm), straightness (0.1 mm/m), and surface finish (Ra 0.4-0.8 μm) are most critical for proper seal function and longevity.
Yes, aluminum alloys (6061-T6) are suitable for lighter duty applications but require thicker walls to achieve equivalent pressure ratings to steel tubes.
