Hi,

I am trying to connect a TPI 605 vacuum gauge to the Zeny VP125+ vacuum pump. The gauge has 1/4 standard male flare connector. The pump has 3/8 standard male flare connector. As I understand, I can do it with this hose: Appion 9802805 MH380006EAB 3/8" Diameter Hose, 3/8" FL to 1/4" FL Vacuum Certified Refrigerant Hose, 6', Blue (sorry, cannot post a link to Amazon).

Is there a connector or a coupler for this (i.e. 3/8 flare female to 1/4 flare female) without a hose?

Thanks.

How should I connect it? I want to pull the vacuum on the car's AC, then monitor it for some time. The pump has 3/8 and 1/4 male flares. They are interconnected on the same coupler. The gauge has 1/4 male flare. The manifold hoses are 1/4 females. Thanks.
