TUBE (P/N as2811-4-025) - New Surplus

The AS2811-4-025 is a seamless aerospace alloy distance tube that maintains precise spacing in airframe assemblies. This spacer tube preserves bolt standoff in control surface hinge assemblies, distributing clamp loads across structural members. Installed around through-bolts to ensure proper alignment and load distribution during assembly.

The tube's seamless construction and aerospace-grade material provide durability in high-vibration environments. Installation requires verification against the aircraft maintenance manual and Illustrated Parts Catalog for specific torque and fitment requirements.
