Superlok Compression Tube Fittings

The patented Superlok i-Fitting is a recent technology that adds benefits and features to the tube fitting’s traditional design. Superlok has incorporated a built-in gap gauge indicator on each of their compression fittings. As a fitting is installed onto tubing, errors are commonly made by over-tightening or under-tightening the compression nut. This is a precise operation and has historically resulted in leaking fittings too often in the field.

With the Superlok design, the tube fitting nut is simply tightened until the built-in gap gauge rings pop away. That moment the rings break away indicates the point of perfect compression. This ingenious design has proven to be a game-changer in the industry by eliminating leaks. As a result, Mako Products backs this technology with a lifetime leak-free warranty.Companies have been able to reduce their exposure to environmental leaks,safety concerns and equipment failure, which is a win-win for everyone.

Series Information

PERFECT TUBE FITTING CONNECTION EVERY TIME!


If you’ve never used Superlok fittings, then you’ve probably also had some poorly gapped and leaky tube fitting connections, and you’re not alone. In the past, it’s been nearly impossible to tell (without the aid of special tools) if you’ve tightened your tube fittings enough or if you have them in too tight. The result in either case is leaks, potential blowouts due to a poor seal, or excessive strain on your tubing. All these small things can add up to real problems. Choosing the right stainless steel compression fittings can make a massive difference in safety and cost for your operations.

Mako Products is your go-to USA source for Superlok fittings and valves. Using patented technology, Superlok tube fittings and valves create a perfect seal every time, so there are no leaks — saving you time, money, and making working environments safer. There’s also no over-tightening during installation, meaning no added stress on your tubes. The built-in gap gauge on every fitting lets you know you’re doing it right. There’s no safer fitting on the market! We guarantee a safe and secure connection with a lifetime guarantee.

Our Superlok compression fittings are interchangeable with all major brands of fittings, like DK-Lok, Parker, Swagelok, and more. You’ll have no trouble introducing them into your system.

HOW OUR SUPERLOK COMPRESSION TUBE FITTINGS WORK


It’s all about the magic of our Superlok i-Fitting with the self-measuring gap gauge already installed on your fitting or compression end valve. We understand that the leading cause of connection failures is an improperly tightened fitting. Improperly tightened fittings can result in leaks or excess system strain, which can lead to increased replacement costs and even threats to your workers’ safety.

Using Mako Products’ Superlok tube fittings, with proprietary i-Fitting technology, means you don’t have to worry because we take the human element out of the equation. Your workers won’t have to use their “gut” to figure out if the fitting is tightened enough or too tight. All they have to do is tighten until the Superlok i-Fitting red ring pops off. You’ll know you’re at the correct compression every time!

Our i-Fitting technology has revolutionized the industry and is part of all of our ss compression tube fittings and tube end valves. Improve the efficiency of your entire tubing system with any of our Superlok products.
