Review: Quality expansion valve. - Quality build. Keep your old expansion valve stud for this new one. This kit come with everything you need. I decided to replace it since I was installing a new air compressor. Review: Good part - Exact match for a 06 impala, worked as good as oem. Note for anyone replacing this, GM uses double threaded studs. A female torx socket is needed to remove the stud. ## Features - Brand New, OE replacement: UAC branded Block Expansion Valve - Premium ISO/TS 16949 quality; tested to meet or exceed OEM specifications - Maximum cooling efficiency ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001DHFKT0 | | Best Sellers Rank | #538,201 in Automotive ( See Top 100 in Automotive ) #251 in Automotive Replacement Air Conditioning Expansion Valves | | Brand | UAC | | Brand Name | UAC | | Connector Type | Flare | | Customer Reviews | 4.6 out of 5 stars 67 Reviews | | Exterior Finish | Machined | | Global Trade Identification Number | 00711307283927 | | Inlet Connection Type | Flare | | Item Dimensions | 2.75 x 2 x 3.5 inches | | Item Type Name | EXP VALVES/ORIF TUBE - EXPANSION VALVE | | Item Weight | 141 Grams | | Item dimensions L x W x H | 2.75 x 2 x 3.5 inches | | Manufacturer | UAC | | Manufacturer Part Number | EX 529458C | | Manufacturer Warranty Description | 1 year manufacturer | | Material | Metal | | Material Type | Metal | | Model Number | UACEX529458C | | Number of Ports | 2 | | Outlet Connection Size | 3.5 Inches | | Outlet Connection Type | Flare or Compression | | Set Name | EXP VALVES/ORIF TUBE - | | Size | 3.5 inches | | Specification Met | oe,oem | | Thread Size | 3.5 inches | | Thread Type | SAE | | UPC | 711307283927 | | Unit Count | 1.0 Count | | Valve Type | expansion valve | ## Product Details - **Material:** Metal - **Brand:** UAC - **Item dimensions L x W x H:** 2.75 x 2 x 3.5 inches - **Exterior Finish:** Machined - **Inlet Connection Type:** Flare - **Outlet Connection Type:** SAE - **Number of Ports:** 2 - **Specification Met:** oe,oem - **Valve Type:** expansion valve - **Global Trade Identification Number:** 00711307283927 ## Images ![UAC EX 529458C A/C Expansion Valve,329 - Image 1](https://m.media-amazon.com/images/I/61-ckxGJn+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality expansion valve. *by R***3 on April 2, 2026* Quality build.
