This Boltigen adapter kit includes both high- and low-side couplers engineered to join R1234yf hoses and gauges to R134a service ports. Each adapter uses brass construction, ball-lock sealing, and a rubber gasket to reduce loss of refrigerant while offering a secure, repeatable connection during charging, diagnosis, or evacuation tasks.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these adapters let me use R1234yf tools on R134a systems?\u003c\/h3\u003e\n\u003cp\u003eThe adapters act as mechanical converters: one for the low-pressure (service) side and one for the high-pressure side. They physically mate a female R1234yf coupling to the corresponding R134a quick-connect shape so that standard service hoses and manifold gauges attach without modifying your existing equipment.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-side adapter: 14mm female R1234yf to 13mm low-pressure R134a coupler.\u003c\/li\u003e\n  \u003cli\u003eHigh-side adapter: 17mm female R1234yf to 16mm high-pressure R134a coupler.\u003c\/li\u003e\n  \u003cli\u003eBrass body for corrosion resistance and durability.\u003c\/li\u003e\n  \u003cli\u003eBall-lock and rubber seal design to limit refrigerant escape.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these adapters leak or damage my system?\u003c\/h3\u003e\n\u003cp\u003eThey are built to minimize leakage by combining a ball-lock mechanism with a molded rubber seal, and they include an automatic closing function when disconnected.
