If you need to connect two pieces of fractional tubing together at a junction that also reduces water pressure, we offer Superlok tube x tube reducing union fittings.
These pieces of hardware help to reinforce the safety of your tubing system while also offering you the ability to remove the connector at any time, which differs from other products. Other connectors require you to cut the tubing to disconnect it, but our inventory instead takes just a few turns to untighten the union.
Additionally, this versatility does not come at the expense of strength. Superlok uses top-tier materials and precision machining with every fitting, which allows them to handle strenuous conditions like temperature cycling, intense vibrations and continual pulsations. A size-appropriate solution is vital for creating leak protection, and we offer various sizes to meet your requirements.
Our i-Fitting system is another feature that sets these products apart from the field. Under- or over-tightening the fitting’s seal can create leaks and cause unnecessary strain on the tubes, both of which cost you money and reduce efficiency. The built-in gap gauge system will indicate when you reach optimal tightness.
