For tight spaces, the ultra-compact VC1 is your go-to VCRT. The capture rod reliably engages the valve core, the first time, every time – no more fishing around for lost valve cores. Swap 1/4" standard service port fitting with optional 5/16" fitting for mini-splits. Lock in the valve core in one try – a gasket secures the valve core pin. Keep the valve core on hand during service with the magnetic cap. Vacuum-rated to 20 microns. A2L compatible.
