Bernard D-1T Centerfire Gas Diffuser

This brass diffuser fits Lincoln Magnum 300 and 400 MIG guns as well as the Tweco Spray Master 450. It accepts AccuLock S contact tips and supports wire diameters from .023 to .125 inches. The threaded connection simplifies parts management for MIG welding setups.

Threaded Centerfire connection limits

The diffuser uses a threaded Centerfire interface that only matches compatible guns and tips listed in the specifications. It will not fit guns that require a different connection style or contact-tip series. Buyers who need a slip-on or alternative mounting type cannot use this part.

Brass material for conductivity

Brass construction provides the electrical conductivity and heat resistance required for the stated wire range. It is not suited for applications that demand a different base metal or coating. Welders who require a non-brass diffuser must select another product.
