Superlok elbow tubing unions connect two pieces of tubing that are the same size at a 90° angle, and feature Superlok i-Fitting technology on all fitting between a 1/4" and 1". These are helpful for redirecting flow especially tight spaces where there is not enough space for the bend radius of your chosen tubing.

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 Tubes

If you need to join two pieces of fractional tubing at a 90° angle but want to avoid traditional joining methods, we have compression elbow connectors to get you going in the right direction.

Some applications require that you work in confined spaces that might pose fire hazards, which makes soldering and flaring unusable. From water transfer to petrochemical, Superlok connectors simplify your system connections while remaining safe and reliable.

The hardware utilizes top-tier materials to remain durable, and the excellent interior finishing improves flow rate and reduces leak risk. You can find various sizes available through our inventory, which allows us to meet a range of demands.

If you need an added layer of security, Mako Products adds its i-Fitting technology to Superlok fittings to create the ultimate compression elbow connector. The built-in gap gauge indicates the ideal tightness level on both seals by popping off the red inspection check rings. When both ends have good tightness, you’ll be less likely to suffer from tubing wear and breaches.
