18673-0003B Jabsco Impeller Nitrile

18673-0003B Jabsco Impeller Nitrile

The Jabsco 18673‑0003 is a high‑quality Nitrile (NBR) flexible impeller designed for pumps handling oil‑contaminated water, diesel, lubricants, or hydrocarbon‑rich fluids. Nitrile construction provides superior resistance to fuels, oils, and emulsions, making this impeller an ideal choice for engine cooling systems exposed to contaminated water, bilge water transfer, and general industrial pumping where neoprene variants would degrade prematurely.

This model belongs to the 673‑series impeller family, commonly used in a wide range of small‑to‑mid size Jabsco and Johnson raw‑water pumps found on marine engines, generators, auxiliary systems, and cooling/transfer pumps.

This impeller is suitable for:

• Engine cooling pumps exposed to oil or contaminated water
• Diesel fuel and hydrocarbon transfer
• Bilge pumping systems
• General‑purpose marine & industrial NBR‑compatible pumps

The Jabsco 18673‑0003 is a 6‑blade oil‑resistant Nitrile flexible impeller designed for G‑profile raw‑water and transfer pumps. With a 2″ diameter, 7/8″ depth, and 1/2″ shaft drive, it matches multiple Johnson, Jabsco, and marine OEM pump models in the 673‑series footprint. Its tough Nitrile construction offers long‑lasting durability where the pumped fluid contains diesel, oil, or contaminated bilge water.
