Product Introduction

The TYDZZQ Series is a professional-grade,dual-purpose manual pump engineered for critical sealing and pressure integrity verification in industrial maintenance. This versatile tool combines a high-pressure grease injection gun with a precise pressure testing function, capable of operating at 70MPa, 105MPa, and 140MPa. Designed for reliability in demanding environments like oil fields, chemical plants, and pressure vessel maintenance facilities, it is the essential solution for injecting sealing grease into flanges and valves, as well as conducting hydrostatic tests on small-volume systems. Its robust, portable design and comprehensive accessory kit make it the go-to tool for ensuring leak-free connections and system safety.
