Xtrweld 11N17 Gas Hose Coupler B Style 5/8 Inch 18 Rhi

Product Description

The XTRWELD 11N17 is a B-style argon inert gas hose coupler designed for TIG welding torches. It features a 5/8 inch-18 right-hand internal (RHI) thread and provides a secure, leak-resistant connection between the inert gas supply hose and the torch body. This coupler is sold individually and is compatible with 125-amp air-cooled TIG torch assemblies. Welding technicians and fabricators rely on this type of fitting to maintain consistent shielding gas flow at the torch, which is critical for clean, contamination-free TIG welds on steel, stainless, and aluminum.

This coupler is suited for use in light industrial, fabrication shop, and field welding environments where WP-9 series air-cooled TIG torches are in service. It is a direct replacement-style fitting for 125-amp air-cooled WP-9, WP-9V, and WP-9P torch configurations. The compact size and standard thread pattern make it a practical service part to keep on hand for torch maintenance and hose replacement jobs.

Key Features

• B-style gas hose coupler for argon and inert shielding gas service
• 5/8 inch-18 right-hand internal (RHI) thread for secure hose connection
• Compatible with 125-amp air-cooled WP-9, WP-9V, and WP-9P TIG torches
• Lightweight at 0.1 pounds for easy handling during torch assembly
• Sold individually for targeted torch repair or hose replacement

Compatibility

Designed for use with 125-amp air-cooled WP-9, WP-9V, and WP-9P TIG torches using a 5/8 inch-18 RHI gas hose connection.

Installation Notes

Installation should be performed by a qualified welding technician or torch service professional. Always shut off the shielding gas supply and relieve line pressure before disconnecting or replacing hose couplers. Thread the coupler by hand first to avoid cross-threading, then snug with appropriate wrenching — do not overtighten, as brass fittings can be damaged. After installation, verify the connection is leak-free by flowing gas and checking with an approved leak-detection method before resuming welding operations.
