A bonded seal combines a metal outer ring with a rubber sealing element that seats against a flat face at the port connection. Where thread tape creates a seal along the threads themselves, a bonded seal keeps that interface clean and consistent without adding bulk or mess. For BSPP fittings especially, this approach gives you a repeatable seal every time you assemble and disassemble the connection, which matters on systems that get serviced regularly.
