Chicago Faucets 177-002JKRBF
The Chicago Faucets 177-002JKRBF is a genuine OEM industrial coupling nut designed for wall-mounted faucets and service sink fittings. This union nut provides the critical mechanical connection between the faucet body and the supply arms or offsets. Featuring a Rough Brass (RBF) finish, it is engineered specifically for "back-of-house" applications where high durability and cost-effectiveness are prioritized over a polished appearance. Constructed from solid, commercial-grade brass, it offers exceptional resistance to thread stripping and thermal stress, ensuring a long-lasting, leak-free seal in the most demanding utility environments.

Expert Insight:
The 177-002JKRBF is the rugged version of the standard chrome union nut, making it the preferred choice for mop sinks, service bays, and industrial wash stations. Because it lacks the delicate chrome plating, it can withstand the harsher environments and more aggressive tool use often found in mechanical rooms. Installation Tip: While this nut is built for utility, it still requires the 1-011JKABNF Union Washer to actually seal the water. When tightening a rough brass union, ensure the faucet body is perfectly aligned with the supply arms to prevent cross-threading. If you’re seeing green oxidation around your existing nuts, it’s time to swap them out before they seize to the arms. Need to pair these with rough brass offsets? Call ProDryers at 888-503-7937!
