Mako Products is the exclusive US source for the patented Superlok I-Fitting. The world's safest fitting with a built-in gap gauge. Superlok is solving leaks and safety issues for industries worldwide with this award winning product line.
Most tube fitting failures are the result of over tightening and under tightening the fitting nut during installation. Only a precision installation will guarantee a fitting connection will contain thousands of pounds of pressure. The only way to get it right, every time, is with Superlok.
Tube fittings are an industry standard and are used in a wide variety of industries. These include, oil & gas, food & beverage, aerospace, mining, semiconductor, ship building, transportation/CNG, power plants, refineries and all types of industrial manufacturing.
These industries depend on precision products and part to keep production output going, while making a safe working environment for their employees. An excessive amount of tube fitting leaks in the market prompted Superlok to design a tube fitting with a built-in gap gauge. With this new technology, an installer no longer has to guess if his connection has been made correctly. As the installer tightens the Superlok fitting to the correct depth, a two piece ring snaps apart, signaling the installer to stop. The rings are engineered to pop at exactly the right time, indicating a precision connection has been made.
Poor fitting connections require time and money to repair or replace. A bad connection can also injure workers because of a high pressure burst, or leak caustic chemicals. The Superlok fitting virtually eliminates the human error factor, setting them apart from their competitors.
Superlok has applied this technology to ball valves, needle valves, check valves and other tubing related products. Superlok carries a full line of instrumentation and control products to support the industries they serve.
