Iwaki 24005 Coupling Nut KBR Series Liquid End Component
The Iwaki 24005 Coupling Nut is a purpose-built replacement part designed for the KBR series of bellows metering pumps, where it plays a small but essential role in keeping the liquid end assembly tight and leak-free. Made from durable, chemically resistant polypropylene, this coupling nut slides over the discharge or suction tubing and threads directly onto the valve housing, holding everything securely in place during operation. It's the kind of part that most operators never think about until it wears out or cracks, at which point a proper fit becomes critical for avoiding drips, air intrusion, or inconsistent dosing.
Anyone who has worked with metering pumps knows that even the smallest components can affect overall reliability. This coupling nut is engineered to Iwaki's original specifications so it seats correctly against the tubing shoulder without over-tightening or pinching the line, which helps preserve accurate flow rates and extend the service life of the surrounding fittings. Whether it's supporting a water treatment system, a plating line, a photographic processing setup, or another industrial fluid-handling application, this part is built to restore a pump's liquid end to like-new condition.
Because it is sourced as a genuine Iwaki replacement component, technicians and maintenance teams can install it with confidence, knowing it will match the fit, tolerances, and material performance of the original equipment. It's a straightforward, no-surprises part that does exactly what it's meant to do: keep the connection secure so the pump keeps running the way it should.

Frequently Asked Questions
Q: Is the Iwaki 24005 Coupling Nut compatible with other Iwaki pump series besides KBR?
A: This coupling nut is designed specifically for the KBR series liquid end configuration, so it's best to confirm compatibility with your exact pump model before ordering.
Q: What tools are needed to install this coupling nut?
A: It should be tightened primarily by hand, with only light tool assistance if needed to snug it down; excessive force can damage the tubing or the nut itself.
Q: How do I know when the coupling nut needs to be replaced?
A: Common signs include visible cracking, difficulty achieving a tight seal, or leaks at the tubing connection point during normal pump operation.
Q: Can this part handle exposure to aggressive chemicals?
A: Polypropylene offers solid chemical resistance for many common dosing fluids, but always check compatibility with your specific chemical media before use.
Q: Does replacing the coupling nut require disassembling the entire pump?
A: No, typically only the tubing connection at the valve housing needs to be accessed, making this a relatively quick maintenance task.
