These are Chinese, the finish quality is average. They weld fine, the o-rings fit, the clamp locks and seals well. These are not as nice, or as high quality as the Vibrant HD clamp’s but they’re half the price, and function almost identically. We have many customers who buy these when they plan on powder coating the piping and clamps anyways. These are not China drop ships, we have these in-stock and ready to ship. We only have the black kits. Lead time on more is typically 2 weeks
The ferrules are aluminum.
