A revolution in fittings design

Highlights
Revolutionary Secondary Containment
Simple installation. Complete confidence. The most efficient secondary containment solution ever. Gemini re-writes the rule book on secondary containment systems by splitting the secondary fitting into two pieces. This revolutionary feature allows you to slide the secondary fitting away so that the primary joint can be fully welded, pressure tested and inspected before welding the secondary fittings for the utmost in system security.
Less Fittings, More Savings
Before Gemini, installing secondary containment was complicated. It required many different types of fittings to be welded together in sequence, piece-by-piece, over primary fittings at each bend. With Gemini three secondary fittings, which are specifically designed to enclose standard one-piece primary fittings, allow you to drastically reduce the number of necessary parts, welds, time and overall cost.
Better by Design
The design of each Gemini fitting in itself allows for the fastest, most efficient installation of secondary containment by reducing the number of welds needed to complete both primary and secondary pipework systems. Additionally, the integrated tabs allow the fitting to constrain itself in place for complete ease of installation without the need for specific clamps.
Weld and Test
No other secondary containment system has ever offered the ability to completely install the primary pipework system and execute integrity testing before closing the secondary system. Discovering a breach after the complete system has been welded can mean having to deconstruct the system to identify the problem, significantly increasing installation time and cost.
Independent Primary
Gemini secondary fittings are completely independent of primary fittings giving you a full 360° interstitial space between the two systems. As a result, a new level of integrity testing is achieved giving you complete peace of mind that both the primary and secondary systems are performing at the highest level.
Cutting Pipe Cost
With Gemini, you finally have a secondary fitting specifically designed for the most efficient usage of pipe. No longer is the secondary pipe diameter determined by the size of the primary fittings. Gemini was designed to enclose standard one-piece primary fittings and then reduce down over the primary pipe cutting both pipe costs and installation time dramatically.
A Single Weld Lead
The same welding leads an installer uses to weld the primary fittings can be used to weld the Gemini secondary fittings giving unparalleled installation efficiency.
Extreme Confidence
The Gemini secondary containment system is simplicity itself. Design engineers, mechanical engineers and manufacturing engineers collaborated to ensure that a final design could be developed quickly without compromise. When you install a pipework system underground, you need to be certain that it will perform flawlessly. Secondary containment is crucial to ensuring safety and performance. With Gemini's integrity testing capabilities, you get a level of confidence which installers and end users have yet to experience until now.
