Superlok male 45° elbow connectors connect tubing to female tapered threads and feature Superlok i-Fitting technology on all compression tube fitting connections between a 1/4" and 1".

Superlok i-Fitting tube fittings and valves are manufactured with the industry's only built-in gap gauge. During installation, the compression nut is simply tightened until the gap gauge rings pop off. When the gap gauge rings pop, it signals the installer to stop. This is the point of perfect compression and seal, which provides an added level of safety and accuracy for companies worldwide. For more information and installation instructions, check out our article and video.

Superlok brings the only game changer to the tube/compression fitting and valve market. This patented innovation ends leaks that are caused by improper tightening procedures, and from the failure to check the installation with a gap gauge, which all manufacturers require. The new, leak-free technology is so precise, that Superlok extends a lifetime warranty on all tube fittings and valves. If you want it done right the first time, get Superlok!

Connects Fractional Tube To Female NPT Thread

If you require a connector to join fractional tubing with a female NPT thread, we offer 45° angle fittings that provide a gentler change of direction when compared to full right angles.

You’ll find our fittings easy to install, giving you a hassle-free experience that involves little-to-no tube preparation. Instead of soldering and flaring, you’ll just screw the male and female ends together before tightening the fractional tubing into place. From agricultural settings to laboratories, you’ll find that 45° tube fittings fit well in applications that need to avoid deposit buildup and flow resistance when changing direction.

Superlok designs emphasize quality construction and improved performance. With superior interior finishing, you’ll experience reductions in particle entrapment and leak risk while improving the overall flow rate.

Mako Products’ improves the fitting’s overall security with unique i-Fitting technology. You’ll no longer need to worry about under- or over-tightening a seal, as the built-in gap gauge on the threaded elbow connector will indicate the ideal tightness level.
