RaceFlux Replacement Aluminum Ferrule for -4AN Smooth Bore PTFE Fittings

Rebuild a -4AN smooth bore PTFE hose end instead of replacing it: this replacement aluminum ferrule is the sacrificial sleeve that compresses onto the PTFE tube inside the fitting. Reassembling a fitting on a fresh cut always needs a fresh ferrule — keep spares on hand and hose ends stay reusable forever.
