This Set can be used to test evacuate and fill automotive air conditioning systems Colour coding on gauges valves and hoses to ensure correct installation LOW - Blue Gauge - 0-120psi . Blue Hose - 1/4 in. FFL x 50 in. HIGH - Red Gauge - 0-500psi. Red Hose - 1/4 in. FFL x 50 in. Yellow Hose - 1/2 in. ACME x 50 in. Large 70mm gauges with impact-resistant lenses. Gauge Accuracy + / -2 percent Sight glass for viewing condition of refrigerant. Quick-connect fittings. High pressure safety valve. Review: Comprehensive and well made piece of kit - Bought this unit after wasting money on a cheaper product, which did not test both high and low pressure systems (my fault). It comes in a rigid plastic case, in which all the components are well laid out and perfect for storage. Instruction manual useful and covers the basics well. Relatively easy to use, although I was only interested in fault finding and have not yet used it to re-pressurize the system, as this is not the problem with my A/C. All in all, a well made product which is probably not up to commercial use, but perfect for the occasional A/C fault finding and well worth the price. Review: Excellent quality for the price - Used only once so far but a good quality product. Most importantly, it has a Schrader purge valve under the sight glass. Bought along with r1234yf connection couplings and r1234yf tap connector as this comes with r134a couplings. ## Features - - Pressure Gauge for Air Conditioner - It was created to allow Terster the systems The Air Conditioner unit of cars with Air Conditioning R134 a, only with the comparison of data bass or art with hot to vary depending on the use of of the system, air conditioner. - Manometer to level indicator for Car Air Conditioning (a/c) - The Bass Guitar The Messe Lementen, valves and hose allows for easy code installation: level indicator Blue 0 – 8.27 bar.

It comes in a rigid plastic case, in which all the components are well laid out and perfect for storage. Instruction manual useful and covers the basics well. Relatively easy to use, although I was only interested in fault finding and have not yet used it to re-pressurize the system, as this is not the problem with my A/C. All in all, a well made product which is probably not up to commercial use, but perfect for the occasional A/C fault finding and well worth the price. ### ⭐⭐⭐⭐⭐ Excellent quality for the price *by W***O on 25 June 2023* Used only once so far but a good quality product. Most importantly, it has a Schrader purge valve under the sight glass. Bought along with r1234yf connection couplings and r1234yf tap connector as this comes with r134a couplings. ### ⭐⭐⭐⭐⭐ Aircon DIY *by M***S on 14 June 2016* An excellent product but you do need to know what you are doing when handling anything to do with refrigerant. I recommend reading The Haynes manual on car aircon before starting. You have to tighten the knurled connection fittings very hand-tight otherwise they can twist loose when you move the hoses. This kit has saved me hundreds in getting the system working on my 2006 Picasso. ## Frequently Bought Together - Air AC Manifold Conditioning System Test Kit R134A FOR Mechanics tools - US PRO INDUSTRIAL 10pc 1/2" Dr Impact Torx Bit Socket Set T20 - T70 2087 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/51156397-air-ac-manifold-conditioning-system-test-kit-r134a-for-mechanics](https://www.desertcart.tn/products/51156397-air-ac-manifold-conditioning-system-test-kit-r134a-for-mechanics) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-15*
