The slide-on yoke is simple to use, whilst the hardened multi-size flaring bar speeds flaring time. This innovative design creates smooth, professional flares on six imperial tubing sizes from 3\/16\" to 5\/8\" O.D.\u003c\/p\u003e\u003ch4\u003eFlares and Burnishes in One Operation\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003euniquely designed flaring cone\u003c\/strong\u003e performs two operations simultaneously — it flares the tubing to the correct 45-degree angle whilst burnishing the surface to a smooth, polished finish.

This results in more reliable, leak-free connections and a professional finish that reflects quality workmanship.\u003c\/p\u003e\u003ch4\u003eSlide-On Yoke: Simple and Fast\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003eslide-on yoke design\u003c\/strong\u003e is simple to use and speeds up flaring operations. Just position the tubing in the flaring bar, slide the yoke over, and turn the handle. No complicated setup, no fumbling with alignment — the sliding die-block design makes flaring straightforward and efficient.\u003c\/p\u003e\u003ch4\u003eHardened Multi-Size Flaring Bar\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003ehardened multi-size flaring bar\u003c\/strong\u003e holds six common tubing sizes in one compact tool.
