No need for separate taps; this single unit works for standard automotive and HVAC refrigerant cans. Pierced & Self-Sealing Can Ready: Works with both traditional puncture-style cans and modern self-sealing cans. The internal safety check valve prevents backflow and leaks, so whether you’re tapping an older pierce-type can or a new self-sealing can, this tap handles it. No refrigerant is wasted when disconnecting, keeping your work area safe and clean.

Just clamp the tap around the can and squeeze to puncture – it’s that simple. Dual outlet ports (1/2" ACME and 1/4" SAE) let you hook up to standard manifold gauge hoses without adapters. Use with your existing manifold gauge set (hose/gauge not included) to service your A/C system in minutes.
