2 stuks betrouwbaar, 2 stuks R410A R22 vloeibare veiligheidsklep, koperen airconditioning koper, 1/4 inch koelmiddelklep met verwijderbare dobbelstenen + r410a r410a koelmiddel 410a snelkoppelventiel

Very nicely made valves, smooth easy to turn and easy to control the flow rate, makes filling of refrigerant or maintenance much easier , they give more control and less waste of refrigerant and makes for a safer and cleaner environment when working on air-conditioning units, I am very pleased with them.
