H561 - Miller H561 Brass Inlet Nut, CGA-024 Connection

Reliable Gas Connections with Miller H561

When you are out in the shop or on the job site, the last thing you want to worry about is a leaky regulator or a stripped fitting. The Miller H561 Brass Inlet Nut is the genuine replacement part you need to keep your gas equipment running safely and efficiently. Designed for setups utilizing the CGA-024 connection, this nut is a small but vital piece of your welding puzzle. Whether you are refurbishing an old Smith regulator or replacing a damaged nut on your current rig, sticking with authentic Miller parts ensures you get the right fit every single time. Using the correct nut is crucial for maintaining the safety of your gas delivery system.

We all know that brass fittings can take a beating over time. Constant tightening and loosening when swapping out tanks can wear down threads or round off the hex, making it harder to get a secure grip with your wrench. A compromised nut isn't just an annoyance; it's a safety risk. A loose connection can lead to gas leaks, wasted consumables, and dangerous situations in the workspace. The H561 is built from durable brass to resist wear and tear, giving you a solid connection that you can trust. It is designed to seat your inlet nipple perfectly, ensuring that gas flows where it is supposed to—into your regulator—and not into the air around you.

Installation is straightforward, but using the correct part is key. Because gas fittings rely on metal-to-metal seals or specific O-ring compressions, the geometry of the nut determines how well that seal holds. The H561 is machined to exact specifications for CGA-024 connections, preventing the headaches associated with mismatched parts. Don't risk your equipment or your safety with "close enough" hardware store finds. Keep a spare H561 in your toolbox so that a stripped thread never shuts down your production. It’s an affordable investment in the longevity of your welding gear and the safety of your crew.
