UNILP3U - Uniweld LP3U Twister® Air/Fuel Kit with TH3 Handle and T-4 Tip

High-Efficiency Soldering with the Uniweld LP3U Twister® Kit

The Uniweld LP3U Twister® Kit is a professional-grade air/fuel torch outfit designed to meet the rigorous demands of the HVAC/R and plumbing industries. This kit is engineered around Uniweld's proprietary Twister® technology, which utilizes a helical blade within the tip to create a high-velocity swirl flame. This unique combustion method ensures the flame wraps around the workpiece, maximizing heat transfer and reducing the time required to reach working temperatures. Whether you are soft soldering large diameter copper tubing or silver brazing critical joints, the LP3U delivers consistent, reliable heat.

At the core of this kit is the TH3 Quick Connect Handle. Designed for comfort and control, the TH3 features a rear valve for precise flame adjustment and an ergonomic grip that reduces operator fatigue during extended use. The Quick Connect mechanism is a standout feature, allowing technicians to snap tips in and out in seconds without the need for tools. This versatility is essential for professionals who frequently switch between different tip sizes to accommodate varying pipe diameters.

The included T-4 Tip is optimized for performance with Propane (LP) gas but is also compatible with MAP//Pro™ (Propylene). It offers a substantial heating capacity, capable of soft soldering up to 2-1/2" O.D. tubing and silver brazing up to 1-1/4" O.D. tubing. By combining aerodynamic gas flow with durable construction, the Uniweld LP3U ensures that every joint is heated evenly and thoroughly, minimizing the risk of cold joints and leaks.
