A3122-18-1J - Textron Aviation Ratcheting Hose Clamp
This clamp has been replaced by Textron Part Number: MS22064-5 as an acceptable alternate for Beechcraft applications
Note: This is a single-use clamp. Once fully engaged, it cannot be removed without cutting the band, which destroys the clamp. It must be installed using the correct, specified NAS398 series installation tool to ensure proper tensioning and locking. Do not use for high-pressure fluid applications.
