OVERVIEW

Extend Your Reach with the Weldcraft 11N17

Every welder knows the frustration of a gas hose that is just a few feet too short. Whether you are moving around a large fabrication table or working on a vehicle lift, having the flexibility to extend your shielding gas line is a game-changer. The Weldcraft 11N17 Inert Gas Hose Coupler is the simple, rugged solution to this common shop problem. By allowing you to connect two standard gas hoses together, it instantly doubles your reach without the expense of buying a custom-length hose.

Built with the quality you expect from Miller Weldcraft, this brass coupler features standard 5/8"-18 RH threads. This means it fits virtually all standard MIG and TIG gas hoses, regulators, and machine connections that use the industry-standard "B-Size" nut. It’s a small part that makes a big difference in shop logistics. Instead of dragging your cylinder cart closer and risking a tip-over, simply couple an extra hose and weld comfortably where the work is.

Don't settle for cheap, ill-fitting hardware that leaks expensive Argon. A leaky connection not only wastes gas but can introduce porosity into your welds by sucking in atmosphere. The 11N17 is machined for a tight, secure seal every time. Keep a couple of these in your toolbox or parts bin; they are the kind of accessory you don't think about until you desperately need one. Compatible with TIG torch power cables and standard inert gas hoses, it is a versatile addition to any welder's kit.

FAQ

The 11N17 features 5/8"-18 Right Hand (RH) female threads on both ends, which is the standard B-Size for inert gas fittings.

No, this coupler has Right Hand threads. Oxygen and fuel gas fittings typically use different thread directions or sizes (e.g., Left Hand for fuel) to prevent cross-connection safety hazards.

Generally, no. Water fittings on TIG torches usually employ Left Hand (LH) threads to distinguish them from gas lines. This coupler is specifically for inert gas lines with RH threads.

It is constructed from high-quality brass, ensuring durability and a secure metal-to-metal seal with standard hose nuts.

Yes, provided your MIG gas hose uses standard 5/8"-18 fittings, which is very common in the industry. It allows you to screw two hoses together.

Typically, no. These compression-style gas fittings are designed to seal on the seated surface (nipple to seat) when tightened. However, ensure the mating surfaces are clean and undamaged.

Yes, this is a genuine Weldcraft (Miller) 11N17 coupler, ensuring compatibility and quality.

This coupler has female threads on both sides. Regulators usually have a male outlet, and hoses usually have female nuts. This coupler is designed to connect two male ends (like two hoses with male nipples, or adapting a male machine outlet). If you are connecting a standard hose (female nut) to a regulator (male outlet), you usually connect directly without this coupler.
