Product Description
The 2677t-4tt is an inline check valve that permits one-way fluid flow while blocking reverse flow in aircraft hydraulic systems. This nonpowered valve isolates circuits and maintains system pressure during pump shutdowns or transient pressure events. Installed in hydraulic lines per SAE ARP4946A standards, the valve prevents backflow that could compromise brake, landing gear, or flight control operation.
Proper installation orientation is critical—flow direction must align with system requirements. Verify compatibility with your aircraft's Illustrated Parts Catalog before installation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
