Product Introduction

TYD1251 Heavy-Duty Ventilation Duct Immersion Wrench belongs to the wrench series of Wuhan Tianyuda. It is integrally cast from cast steel and reinforced via heat treatment. The octagonal socket features a standard inner diameter of 88mm with an extra thickened wall, which enables tight fitting and effectively prevents slipping. It is specially designed for disassembly and assembly of octagonal nuts matched with ventilation ducts, fire dampers and air volume regulating valves. After shot blasting for rust removal, the wrench is finished with red epoxy electrostatic powder coating, which delivers outstanding resistance to oil stains, moisture and mild acid-base corrosion. Its striking red color offers high visibility on construction sites, and the coating layer resists peeling and rusting. Adopting a deep immersion socket structure, it can reach narrow spaces such as pipe interlayers and flange recesses, making it a dedicated heavy-duty tool for the installation, maintenance and repair of HVAC and fire ventilation engineering systems.
