Machined from 360 brass alloy bar stock, this diffuser delivers consistent dimensional stability and reliable electrical conductivity across medium to heavy duty welding cycles. At 1.955 inches in length with a 9\/16 inch-18 UNC-2A thread size and six 0.094 inch gas holes, it provides uniform shielding gas distribution at the weld zone. The part number is roll-stamped on the external surface for fast identification in the field. Sold in a pack of five.\u003c\/p\u003e\u003cp\u003eThis gas diffuser is engineered for use with slip-on nozzle assemblies on the 450A Tweco Spray Master MIG gun series and is also compatible with Tweco Eliminator front-end consumable systems. It fits a properly threaded conductor tube and is suited for demanding production welding environments where consistent gas coverage and secure nozzle retention are critical. Licensed welding technicians and industrial maintenance professionals working with high-amperage MIG guns are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated for MIG welding applications up to 450 amps\u003c\/li\u003e\n\u003cli\u003eMachined from 360 brass alloy bar stock for consistent dimensional stability and electrical performance\u003c\/li\u003e\n\u003cli\u003eSix 0.094 inch gas holes deliver uniform shielding gas distribution\u003c\/li\u003e\n\u003cli\u003eMetal flat spring on the OD allows slip-on nozzle assemblies to slide over and locks the nozzle in place during welding\u003c\/li\u003e\n\u003cli\u003eSilicone O-ring provides a secure seal against the nozzle assembly\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on exterior surface for quick identification\u003c\/li\u003e\n\u003cli\u003eSold as 5 units per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with slip-on nozzle assemblies on the 450A Tweco Spray Master MIG gun series and Tweco Eliminator front-end consumables.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified welding technician or industrial maintenance professional. De-energize and allow the MIG gun to cool completely before replacing consumables. Thread the diffuser onto the conductor tube by hand first to avoid cross-threading, then snug with appropriate hand tools. Verify the silicone O-ring is properly seated before reattaching the nozzle assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.955 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: Six at 0.094 inches each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 450A\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\u003ePackage Quantity\u003c\/strong\u003e: 5 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246359304\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1540-1127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344402776370,"sku":"1540-1127","price":168.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546136.jpg?v=1782035051","url":"https:\/\/voomisupply.com\/products\/tweco-1540-1127-mig-gas-diffuser-450a-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
