Each foam cylinder is specially formulated to travel through the lineset when driven by compressed nitrogen at up to 70 psi, removing contaminants, moisture, and debris from the line interior. The flexible foam construction allows each pig to navigate past common lineset deformations, including kinks and twists, without getting lodged. HVAC technicians use these pigs during new system commissioning or when cleaning existing linesets before brazing new connections.\u003c\/p\u003e\n\u003cp\u003eThese foam pigs are suitable for both ducted and ductless HVAC applications where 7\/8-inch linesets are used. They are a standard maintenance and commissioning tool for residential and light commercial mini-split and split-system installations. The pigs are driven through the line using a compressed nitrogen source, making them compatible with standard nitrogen purging setups already common on HVAC service rigs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpecially formulated foam construction navigates kinks, twists, and lineset deformations\u003c\/li\u003e\n  \u003cli\u003eRated for use at up to 70 psi air or compressed nitrogen pressure\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for 7\/8-inch linesets\u003c\/li\u003e\n  \u003cli\u003eCompatible with both ducted and ductless HVAC systems\u003c\/li\u003e\n  \u003cli\u003e10-pack quantity supports multiple lineset cleaning jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 7\/8-inch refrigerant linesets in both ducted and ductless HVAC systems.

Use a regulated compressed nitrogen source and never exceed the rated 70 psi drive pressure. Ensure the discharge end of the lineset is directed to a safe, open area before driving the pig through. Follow all applicable mechanical and refrigerant handling codes during lineset service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLineset Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure Rating\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\u003eCompatible System 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: HLP078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILMOR","offers":[{"title":"Default Title","offer_id":51284054933810,"sku":"HLP078","price":30.31,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278509.png?v=1781067302","url":"https:\/\/voomisupply.com\/products\/hilmor-hlp078-lineset-cleaner-foam-pigs-7-8-inch-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
