Frequently Asked Questions

Questions about use and selection

Does an R134a adapter work on an R1234yf vehicle?

No. R1234yf service ports have different dimensions; the adapters are deliberately incompatible to prevent mixing. Each refrigerant type needs its own coupler set.

Does the refrigerant have to be recovered to replace a valve core?

With the ELC‑A56 valve core replacement kit, a leaking valve core is replaced without recovering the refrigerant from the system; no refrigerant loss and no recharging cost.

Why is the O‑ring material HNBR?

HNBR is resistant to refrigerant and compressor oil; a standard NBR seal swells in the A/C circuit and causes leaks.
