STP A/C Pro™ R-134a Professional Digital Gauge & Hose

Easy to use and great item

Unfortunately it wouldn't pierce the cans I bought with it going to see if I can have a refund sad thing is it looks so easy to use too

Make sure you follow the steps carefully. When refilling, occasionally shaking and inverting the bottle is essential.I’ve a few cars so being able to use it multiple times is really good value.

Connected the can/bottle but the gauge would not pearse the can so would not fill.

Purchased as it had a digital readout. Included leaflet provides clear instructions on how to use. Easy to connect and disconnect. Unfortunately if you have a non normal reading (potentially indicated as an excessive pressure reading) the problem can't be diagnosed with just the low pressure side gauge on its own, you need the high pressure reading as well. Also the compressor needs to be running (compressor clutch engaged) to provide proper readings so before purchase check this component is functioning.

Seems to be letting the gas escape from the trigger. No way of contacting to get a replacement. Ended up wasting a bottle worth £69

Seems good, bought this to check and fill a/c but with a car scanner found my high pressure sensor failed so no chance of using, but might need in the near future.

This is a really good tool for filling up your air con very accurate readings don't get a cheap one use this one its digital read out and it can be kept for everything you need it to give a nice cool air con
