## Description

2 Pcs Blue Replacement Valve Caps for Car Air Conditioning, Leakproof R134a AC System Charging Port Caps Valves Engine Cooling and Climate Control(High and Low Pressure)

Review: Easy fitment high visability - This item does exactly its intended purpose, there are two caps one for high pressure and one for low pressure, both have lettering embossed on them so you cannot mistake them, plus they are two different sizes to correspond with valves, they seem to made of very durable material, fitted perfectly onto valves in car. Great buy and great value for money.
Review: H fits perfect. L won't thread on at all. - These seem like good quality. St the end of the day, it's simply a plastic cap that goes over the H and L valves. Whilst the H one fitted perfectly (didn't have one fitted before) the L simply won't screw on at all. Thankfully, my existing L one was still there, so not a problem for me.

### ⭐ No O-Rings / Seals

The advert clearly shows the caps come with the O-Rings / seals, but the caps I received didn't, which means that they are unfit for purpose.
