Mobile auto A\/C techs sealing leaks without recovering refrigerant. Refrigeration contractors restoring system pressure on walk-in coolers and reach-ins. Fleet maintenance crews keeping commercial A\/C units running. Anyone whose customer's system is losing 1–2 oz per week and they don't want a $1,500 compressor replacement.\u003c\/p\u003e\u003ch3\u003eWhen to use it\u003c\/h3\u003e\u003cp\u003eFor \u003cstrong\u003emicro-leaks, pinhole leaks, and porous metal leaks\u003c\/strong\u003e that drop pressure over weeks or months but aren't visually locatable. Screw the 45° adapter onto the syringe, connect to the low-side service port, inject with the system running. \u003cstrong\u003eNo refrigerant recovery required\u003c\/strong\u003e. One 2 oz syringe treats up to a 6-ton system. NOT for mechanical leaks at loose fittings, fractured copper, or split hoses — replace those components.\u003c\/p\u003e\u003ch3\u003eWhy HCLSK2 vs cheap stop-leak products\u003c\/h3\u003e\u003cp\u003eCheap stop-leak uses polymer chemistry that hardens throughout the system and \u003cstrong\u003eclogs TXVs, orifices, and evaporator coils\u003c\/strong\u003e. HCLSK2's refrigerant-soluble formula only reacts at leak points where it contacts atmosphere — the rest of the system stays clean. Anti-corrosion additive prevents the underlying corrosion that caused the leak from spreading. Rated to 800 PSI for R-410A high-pressure systems. Universal oil and refrigerant compatibility.\u003c\/p\u003e\u003cp\u003eAvailable in \u003cstrong\u003esingle 2 oz syringe\u003c\/strong\u003e, \u003cstrong\u003e2-pack, 4-pack, and 12-pack\u003c\/strong\u003e at trade pricing. \u003cem\u003eManufactured in the USA to industry HVAC-R sealant performance standards.\u003c\/em\u003e\u003c\/p\u003e","brand":"HCPRO","offers":[{"title":"Each 2 oz Syringe","offer_id":47712935608492,"sku":"02-0076","price":64.53,"currency_code":"USD","in_stock":true},{"title":"2 oz Syringe (2 Pack)","offer_id":47712935641260,"sku":"02-0076-2","price":130.59,"currency_code":"USD","in_stock":true},{"title":"2 oz Syringe (4 Pack)","offer_id":47712935674028,"sku":"02-0076-4","price":187.3,"currency_code":"USD","in_stock":true},{"title":"2 oz Syringe (12 Pack)","offer_id":47712935706796,"sku":"02-0076-12","price":494.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/1293\/7132\/files\/d53ace0a-Product_Image_2000x2000_0063_PROD_IMG_B2C_2OZ_LEAK-SEALER_HVAC-R_2_e1693fda-515e-4ff9-ab48-a0d3ada6f9d1.jpg?v=1793019699","url":"https:\/\/splypro.com\/products\/hcpro-hclsk2-hvac-r-leak-sealant","provider":"SPLYPRO","version":"1.0","type":"link"}
