Frequently Asked Questions

Q: What types of tubing can the CT-428 close quarters tubing cutter cut?

A: The CT-428 tubing cutter is designed to cut a wide range of small-diameter tubing materials, including copper, brass, aluminum, stainless steel, CSST gas piping, and plastic tubing. It handles diameters from 3/16 in. up to 1-1/8 in., making it versatile for plumbing, HVAC, and gas piping applications.

Q: Is this tubing cutter suitable for use in tight or confined spaces?

A: Yes — the CT-428 is specifically engineered for close-quarters work. Its compact, slim profile allows it to operate in tight wall cavities, under sinks, and in other cramped areas where a standard full-size tube cutter would not fit.

Q: How do I control the cutting depth and pressure on this tubing cutter?

A: The large knurled feed screw knob allows you to easily adjust and control the amount of cutting pressure applied to the tubing. Simply rotate the knob gradually as you rotate the cutter around the tube for a clean, precise cut without deforming or flaring the material.

Q: Does the CT-428 tubing cutter produce clean cuts suitable for flare fittings?

A: Yes. The grooved rollers are designed to produce close-to-flare cuts, which are ideal for use with flare fittings commonly found in plumbing, HVAC, and gas line installations. This minimises additional preparation work after cutting.
