A leakage protector for preventing gases, vapors and liquids emanating as leakage through the seals or packings around the reciprocating rod of reciprocating rod-type fluid displacement arrangements, such as those of pumps, compressors, and the like from reaching the surrounding environment. The leakage protector has an adaptor for mounting a leakage recovery unit of the protector on the casing of the reciprocating rod arrangement in proximity to its packing or seal. The reciprocating rod passes through the leakage recovery unit with clearance, and a bellows component is sealingly attached to the reciprocating rod at one end and to the leakage recovery unit at an opposite end. The interior of the bellows component is able to communicate with the interior of the recovery unit, and the leakage recovery unit is connected to a vacuum recovery line via a vacuum recovery fitting having a valve which causes the vacuum recovery line to be sealed relative to the interior of the leakage recovery unit except when pressure increases occur within the interior of the leakage recovery unit due to the entry of leakage. A fluid sensor can also be provided to shut down operation of the reciprocating rod arrangement, should excessive leakage occur.
