Machined from 360 brass alloy bar stock, this diffuser delivers consistent dimensional stability and reliable electrical conductivity in medium to heavy duty welding environments. It measures 1.896 inches in overall length with a 9\/16 inch thread size and features six 0.094 inch gas ports for even shielding gas distribution. The part number is roll-stamped on the external surface for quick identification in the field. Sold in a pack of five, it is installed by welding technicians as a front-end consumable during routine gun maintenance.\u003c\/p\u003e\u003cp\u003eThis gas diffuser is intended for use with slip-on nozzle assemblies on 450 A Tweco Spray Master MIG gun series as well as Tweco Eliminator front-end consumable systems. It is suited for medium to heavy duty standard welding applications and fits a properly threaded conductor tube on compatible MIG guns. The included metal flat spring wraps the OD of the diffuser, allowing nozzle assemblies to slide over and lock in place during the welding process. A silicone O-ring provides a secure seal against the nozzle assembly, and a conduit set screw retains the conduit liner.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMachined from 360 brass alloy bar stock for consistent dimensional stability and strong electrical properties\u003c\/li\u003e\n\u003cli\u003eSix 0.094 inch gas ports deliver even shielding gas coverage across the weld zone\u003c\/li\u003e\n\u003cli\u003eMetal flat spring on OD allows slip-on nozzle assemblies to slide over and holds the nozzle 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\u003eConduit set screw retains the conduit liner in position\u003c\/li\u003e\n\u003cli\u003ePart number roll-stamped on external surface for fast identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 450 A Tweco Spray Master MIG gun series and Tweco Eliminator front-end consumable systems using slip-on style nozzle assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified welding technician with the MIG gun fully powered down and disconnected from the wire feeder before servicing front-end consumables. Thread the diffuser onto the conductor tube by hand first to avoid cross-threading, then snug with the appropriate wrench. Inspect the silicone O-ring and flat spring for wear each time the diffuser is replaced to maintain a proper gas seal and nozzle retention.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.896 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inch\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 Current 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\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\u003eWidth\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246301013\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: 1540-1135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344908124466,"sku":"1540-1135","price":152.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546139.jpg?v=1782045160","url":"https:\/\/voomisupply.com\/products\/tweco-1540-1135-mig-gas-diffuser-450a-brass-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
