Hobo Freight screw type separator


I have one like that from harbor freight but it was part of a front end kit. I just tighten it till they pop. Just make sure the threads a lubed with good oil or grease. Most people don't lube their tools. I've had it close to 10 years and was just using it 2 weeks ago, still going strong.
