Limited reusability is possible, but ferrules may deform permanently. For critical applications, it is recommended to replace ferrules after disassembly to ensure a reliable seal.
Single ferrule fittings use one ferrule for both gripping and sealing, while double ferrule fittings have a front ferrule for sealing and a back ferrule for gripping, offering better vibration resistance and seal integrity.
Yes, especially double ferrule designs, which provide superior resistance to vibration and thermal cycling due to their mechanical grip and seal separation.
