We Have The Tools You Need For Cone & Thread Fittings

Rent our manual tool to use on site, or have us use our automatic tool


Cone and thread tubing and tube niples

The equation for a High pressure working environment = stronger fitting + stronger tubing. But those tube bends can't be done with your hand tube-bender, so contact us to get those bends looked after. 


Longtime readers of our blog might recall a post about our IPT fittings for high-pressure applications. These extra-strong fittings are designed to handle pressures up to 60,000 psig or 4134 bar.

Just as high pressure demands a stronger fitting than usual, so does it demand stronger tubing. The special cold-drawn tubing for IPT fittings is harder and has thicker walls than our standard tubing. The threads must be cut into the ends, and finished off with a cone at a 59-degree angle. It fits into the primary seal surface of the fitting, which has a 60-degree angle. The tube walls are thick to that material can be cut away for the threads. In a sense it's really a very small pipe

It's tool time

So how to you get the threads and cone on the end of the tubing? We offer two options. You can rent a tap-and-die set from us, along with our bench-top tube bender. (Our handheld bender won't be up to the job for this thicker tubing.)

But if you prefer, we can do the work for you at our shop so that you save time and effort in the field. Our automatic tools in our own shop can easily perform work that is much harder to do on site. We can produce as many pieces of tubing as you need, and can even do things such as put a 90-degree nipple on the tubing.

Even if you are an old hand at tube bending, the harder steel and thicker walls mean slightly different rules. The bend radius must be larger, at least 1.25 inches for quarter-inch tubing.

These cone-and-thread fittings are designed specifically for the oil and gas, chemical, petrochemical, alternative fuel, and instrumentation industries. We'll be glad to tell you more and talk about your specific needs. All it takes to start the conversation is a call to Edmonton Valve at 780-437-0640, or a quick note through our website.
