It’s suitable for cars and light trucks that explicitly use HFO-1234yf refrigerant, and for owners who want a product that lubricates seals without leaving problematic polymers. It is not appropriate for vehicles that use R134a or for systems with major refrigerant loss that require component replacement.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this product in an R134a system?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This formula and coupler are made for HFO-1234yf systems only and should not be used in R134a systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How many vehicles does one can treat?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: One overfilled can is intended to treat a single vehicle; it includes extra to offset residual hose fluid.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"TSI Supercool","offers":[{"title":"Default Title","offer_id":67588169662649,"sku":"B01981J9DU","price":76.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/tsi-supercool-front-can.jpg?v=1790516883","url":"https:\/\/redleafauto.ca\/products\/tsi-supercool-hfo-1234yf-total-leak-stop-plus-with-u-v-dye-1-can-quick-connect-hose-non-polymer-formula","provider":"Redleaf Auto","version":"1.0","type":"link"}
