What are normal R12 operating pressures?

Normal operating pressures for R12 refrigerant typically range from about 30-40 psi on the low side and 200-250 psi on the high side, depending on the ambient temperature and system design. These pressures can vary slightly based on specific equipment and conditions. It is important to refer to the manufacturer's specifications for precise values tailored to a particular system. Always handle refrigerants with care and ensure proper safety protocols are followed.
