The gauge face shows the unit in psi (also see product details), while the temp-pressure mapping appears to be F-psig.** A: PSIG only. When disconnected the gauges read zero. The P-T chart for R-134a is fairly accurate to within around 3 degrees F, as far as I can tell, which means it is definitely PSIG/TempF. **Q: Is this fahrenheit? i do not want celsius? the pictures show f but the third bullet point on the description says celsius? what is the truth?** A: These have Fahrenheit scale on them. **Q: Under what circumstances should the pins (as shown in D, similar to tire valve pins) be unscrewed from the ends of hoses using the red tool?** A: I would say these are extra valve cores in case one goes bad **Q: Are these low loss fittings?** A: If you buy this product, you will get: 1pc 3-way HAVC freon gauge (1/4" male), 3pc hoses (1/4" female), 2pc quick couplers (1/4" male), 1pc ACME adapter (1/4" Male to 1/2" Female), and 1pc can tap (piercing-style) (1/4" male).
