Connects Fractional Tubes

Whether it’s splitting up one flow or bringing together two separate ones, these Superlok compression reducing tees will handle the test.

These fittings, which come in many different sizes to meet your circumstances, and make it easy to bring together three different fractional tubes. The system installs quickly and requires little-to-no tube preparation, allowing you to bypass soldering and flaring.

Often applied to pneumatic, hydraulic and instrumentation systems, these fittings fill the additional role of reducing the interior pressure of whatever is flowing through it. This feature is vital for ensuring safety in many industries. Superlok manufactures its fittings using the best materials and precise production practices, which results in a strong product that can handle excessive pressure, extreme temperatures and persistent vibrations.

Mako Products has also implemented the i-Fitting system, which further reduces the chances of leaking by finding the perfect level of tightness. The No. 1 cause of tubing issues is under- or over-tightening seals, but our built-in gap gauge will signal the ideal level on both sides to ensure balance.

Available tube sizes:
  • 3/8"
  • 1/2"
  • 5/8"
  • 3/4"
  • 1"
