Machined from 360 brass alloy bar stock, it delivers consistent dimensional stability and reliable electrical conductivity in medium to heavy-duty welding applications rated up to 450 A. The diffuser measures 2.043 inches in length with a 9\/16 inch-18 UNC-2A thread size and features six 0.094 inch gas holes for uniform shielding gas distribution. A silicone o-ring seals the diffuser against the nozzle assembly, and a metal flat spring on the OD retains the nozzle during the welding process. Licensed welders and MIG gun technicians install this component as a standard consumable replacement.\u003c\/p\u003e\n\u003cp\u003eThis gas diffuser is suited for medium to heavy-duty MIG welding environments where consistent gas coverage and electrical performance are required. It is compatible with 1\/16 inch wire conduit liners and properly threaded conductor tubes used in 450 A MIG gun setups. The Eliminator front-end consumable configuration makes it a practical replacement in production welding, fabrication shops, and heavy industrial applications. The part number is rolled-stamped on the external surface for quick identification during consumable changeovers. Sold in a pack of five units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMachined from 360 brass alloy bar stock for consistent dimensional stability and electrical conductivity\u003c\/li\u003e\n  \u003cli\u003eSix 0.094 inch gas holes provide uniform shielding gas distribution around the weld zone\u003c\/li\u003e\n  \u003cli\u003eMetal flat spring on the OD retains slip-on nozzle assemblies securely during welding\u003c\/li\u003e\n  \u003cli\u003eSilicone o-ring seals against the nozzle assembly to prevent gas leakage\u003c\/li\u003e\n  \u003cli\u003ePart number rolled-stamped on the external surface for easy field identification\u003c\/li\u003e\n  \u003cli\u003eRated for medium to heavy-duty applications up to 450 A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with slip-on style nozzle assemblies on 450 A MIG gun series and Eliminator front-end consumables.

Always power down the welding machine and allow the gun to cool before replacing consumables. Thread the diffuser onto the conductor tube using the 9\/16 inch-18 UNC-2A thread engagement and verify the o-ring is properly seated before attaching the nozzle assembly. Do not over-tighten, as this may damage the brass threads or deform the o-ring seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.043 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inch-18 UNC-2A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Holes\u003c\/strong\u003e: 6 x 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Conduit Liner Size\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 450 A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 360 Brass Alloy Bar Stock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TWECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1540-1137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51348053295410,"sku":"1540-1137","price":210.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546141.jpg?v=1782119341","url":"https:\/\/voomisupply.com\/products\/tweco-1540-1137-gas-diffuser-450a-mig-welding","provider":"Voomi Supply","version":"1.0","type":"link"}
