The CT-343/CT-343J Pressure-resistant Self-piercing R134a (USA) Dedicated Can Tap Valve uses a brass valve body and a self-piercing structure, and is suited to US-specification R134a cans. The CT-343 has a zinc alloy/aluminum knob and the CT-343J an aluminum knob.
Product Advantages
1. The self-piercing plus pressure-resistant design keeps the seal stable during charging.
2. The zinc alloy/aluminum knob feels sturdy, and the J version's aluminum knob gives a better grip.
3. It belongs to the same R134a (USA) range as the CT-342, so users can choose by structural preference.
