Interchange & Intermix

“Interchange” and “intermix” are two critical definitions of instrumentation tube fittings that are often confused with one another. Interchanging refers to using one manufacturer's nut and ferrule system with another manufacturer's body to build a single tube fitting assembly to ensure a tight, leak-free connection. Intermixing is a more general practice, where technicians and operators mix and match any combination of components—not just the nut and ferrule—with compatible components by other brands.

SSP manufactures interchangeable and intermixable components that are compatible with other brands. Our components are built to meet or exceed the pressure ratings and other standards of instrumentation systems. Learn more below about the differences between interchanging and intermixing, as well as the different tube fittings available.

Demystifying Interchange and Intermix Information

Knowing the difference between interchanging and intermixing is crucial for ensuring that operators construct instrumentation systems that are safe, reliable, and fully functional. Following the wrong information to repair fittings could endanger facilities or lives.

Many sources regarding interchanging and intermixing contradict one another. For example, some manufacturers insist intermixing and interchanging cannot create reliable, safe fittings. Some claim that interchanging is safe but intermixing is not. Others say that both interchanging and intermixing are safe practices as long as they are performed with compatible components. 

SSP falls in this last category. As experts in fitting, valve, and tubing systems, we know that interchanging and intermixing are both acceptable practices with the right expertise and components. At SSP, we have successfully intermixed and interchanged components with approved Swagelok®, Hoke®, and Parker Hannifin® parts. Before attempting interchange and intermix processes in your facility, confirm that you’re working with properly rated components and have the appropriate guidance.

Interchange

Interchange

Interchange means that the nut and ferrule(s) combination from SSP can be assembled with the body of a compatible brand, and vice-versa, to produce a working, leak-tight fitting.

Intermix

Intermix

Intermix means that any combination of SSP tube fitting components can be used with the components of a compatible brand giving the user the opportunity to achieve maximum safety and value.
