Superlok has created the world’s first tube fitting with a self-measuring gap gauge installed on each fitting and compression end valve. This new innovation helps eliminate over tightening and under tightening upon installation, which can lead to replacement expenses and worker safety concerns.

The Superlok i-Fitting is a simple idea that solves a big problem in the industry. Improperly tightened fittings account for most connection failures. This patent virtually eliminates the human error factor and helps make a safer working environment. This industry changing technology works for all of Superlok’s tube end valves and fittings. Simply tighten the Superlok i-Fitting until the red ring pops off, which happens at the point of correct compression – every time!
