Each foam cylinder is engineered to flex and compress as it travels through the lineset, allowing it to pass through deformations, kinks, and twists that would stop a rigid cleaning tool. Propelled by compressed nitrogen at up to 70 psi, these pigs sweep loose particulates, moisture residue, and debris from copper lineset interiors before system commissioning or after a compressor burnout. HVAC technicians use them as part of a proper lineset flush procedure on both ducted and ductless systems.\u003c\/p\u003e\n\u003cp\u003eThese foam pigs are suited for use on residential and light commercial HVAC installations wherever 3\/4-inch linesets are present. They work with both ducted split systems and ductless mini-split configurations. A clean lineset reduces the risk of contaminant-related compressor damage and helps protect the refrigerant circuit after a burnout event or during a system changeout. Technicians typically run one or more pigs through the lineset until the expelled pig shows no visible debris or discoloration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFormulated foam construction flexes through kinks, twists, and lineset deformations\u003c\/li\u003e\n  \u003cli\u003eRated for use at up to 70 psi drive pressure\u003c\/li\u003e\n  \u003cli\u003ePropelled by compressed nitrogen for safe, dry operation inside refrigerant lines\u003c\/li\u003e\n  \u003cli\u003eCompatible with both ducted and ductless system linesets\u003c\/li\u003e\n  \u003cli\u003eSized specifically for 3\/4-inch linesets for a proper cleaning fit\u003c\/li\u003e\n  \u003cli\u003e10-pack quantity supports multi-pass cleaning procedures or multiple jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 3\/4-inch refrigerant linesets in both ducted and ductless HVAC systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLineset cleaning with foam pigs is performed by licensed HVAC technicians. Recover all refrigerant and isolate the lineset from system components before introducing any pig or pressurized nitrogen. Use only dry compressed nitrogen as the drive gas — never use oxygen or air, as both introduce moisture or combustion risk into the refrigerant circuit. Confirm all fittings and end connections are secured and directed to a safe recovery area before initiating the push.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLineset Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Pressure\u003c\/strong\u003e: 70 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Source\u003c\/strong\u003e: Compressed nitrogen\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Type\u003c\/strong\u003e: Ducted and ductless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 10 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: HILMOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HLP034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILMOR","offers":[{"title":"Default Title","offer_id":51283970654514,"sku":"HLP034","price":29.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278507.png?v=1781064587","url":"https:\/\/voomisupply.com\/products\/hilmor-hlp034-lineset-cleaner-foam-pigs-3-4-inch-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
