Description

Product Overview

The Tigbear Retrofit Valve Set is engineered for automotive air‑conditioning technicians who need a dependable solution for converting legacy refrigerant systems to modern, environmentally‑friendly fluids. Constructed from high‑grade brass and zinc alloy, the valve offers excellent corrosion resistance and a robust 32 bar maximum pressure rating. It features a 7/16″‑20 UNF (1/4″) compression thread, a built‑in check valve to prevent backflow, and a low‑side quick coupler that fits R12, R22, R502, and R134A circuits. The kit includes a 20‑piece service access valve, a hex key wrench for easy installation, and dust caps to protect the ports when not in use.

Usage

Designed for retrofitting refrigerant lines on cars, trucks, and light commercial vehicles, this valve set excels in both workshop and field environments. Whether you are converting an older R12 system to R134A or performing routine maintenance on an R22 unit, the quick‑coupler design reduces installation time and minimizes the risk of leaks. The valve’s compact 3 × 2 × 1 inches footprint allows it to fit in tight engine bays, making it suitable for professional service bays, mobile repair units, and even DIY garage projects.
