Review: Works as described, but..... - Works as described. But if you are retrofitting your car from R12 to 134a, you might want to consider getting a full retrofitting kit. You get 3 cans of 134a, both low and high side adapters, and the hose/gauge to run the can into your car. The full set I got was only about double the cost of this one fitting. I bought this fitting to work with the pierce valve I got to allow us to charge our freezer that uses 134a, but had no fill port on the line. Now I can charge it using automotive style 134a refill cans. Review: Perfect. - Perfect for what I needed. I wish I could've found one of these in a real physical store, but desertcart saved the day after I had gone to Autozone and Home Depot... This works excellent if you're trying to refill an R12 system with R134a, works flawlessly and doesn't leak. ## Features - Professional grade retrofit valve adaptor for automotive air conditioning systems converting from R-12 to R-134A - For 7/16 inch low side port - Includes dust cap and retrofit label - Fits all vehicles pre-1994 - Works with R-134a refill fittings ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004QKT9PC | | Best Sellers Rank | #2,271,126 in Automotive ( See Top 100 in Automotive ) #529 in Automotive Replacement Air Conditioning Control Valves #886 in Automotive Replacement Heater Control Valves #1,576 in Automotive Replacement Air Conditioning Clutches & Parts | | Brand | A/C Pro | | Brand Name | A/C Pro | | Connector Type | Barb | | Customer Reviews | 4.5 out of 5 stars 444 Reviews | | Exterior Finish | painted | | Global Trade Identification Number | 00048168025862 | | Inlet Connection Type | Barb | | Item Dimensions | 6.4 x 2.7 x 1 inches | | Item Weight | 22.68 g | | Item dimensions L x W x H | 6.4 x 2.7 x 1 inches | | Manufacturer | Interdynamics | | Manufacturer Part Number | VA-1L | | Material | Alloy Steel, Stainless Steel | | Material Type | Alloy Steel, Stainless Steel | | Model Number | VA-1L | | Number of Items | 1 | | Number of Packs | 1 | | Number of Ports | 2 | | Outlet Connection Size | 0.44 inches | | Outlet Connection Type | NPT | | Size | 7/16 Inch | | Specification Met | certified | | Thread Size | 7/16 Inch | | Thread Type | NPT | | UPC | 048168025862 | | Unit Count | 1 Count | | Valve Type | retrofit valve | ## Product Details - **Material:** Alloy Steel, Stainless Steel - **Brand:** A/C Pro - **Item dimensions L x W x H:** 6.4 x 2.7 x 1 inches - **Exterior Finish:** painted - **Inlet Connection Type:** Barb - **Outlet Connection Type:** NPT - **Number of Ports:** 2 - **Specification Met:** certified - **Global Trade Identification Number:** 00048168025862 - **Manufacturer:** Interdynamics ## Images ![Certified A/C Pro Car Air Conditioner Adapter Valve, Retrofit Valve Adaptor Converts Refrigerant from R-12 to R-134A, Includes Dust Cap and Retrofit Label, InterDynamics - Image 1](https://m.media-amazon.com/images/I/51jKv1sq9UL.jpg) ![Certified A/C Pro Car Air Conditioner Adapter Valve, Retrofit Valve Adaptor Converts Refrigerant from R-12 to R-134A, Includes Dust Cap and Retrofit Label, InterDynamics - Image 2](https://m.media-amazon.com/images/I/711dt2uCsrL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as described, but..... *by J***S on September 3, 2017* Works as described.
