Double-See™ Double Containment Vinyl Piping System

Double-See™ is fast and easy to install, and is available with a complete selection of pipes, fittings, termination fittings, closure couplings, leak detection, and containment boxes.

Double-See is available in PVC and CPVC; either material may be primary or secondary (PVCxPVC, CPVCxPVC, PVCxCPVC, CPVCxCPVC) with Clear PVC always being an option for the containment pipe. System size options range from ½” × 2” to 8” × 12” meeting virtually any media flow requirements.

Simple installation

The installation versatility of Double-See allows for simultaneous jointing throughout a system or in combination with patented closure couplings. These enable practical compliance with ASME B31.3 Code requirements.

Large standard selection

A large selection of standard components is available. Additionally the Double-See™ system is also available with custom designed spools and leak detection options.

Compensated for thermal expansion

An innovative centering design compensates for thermal expansion. This allows Double-See to be used in both aboveground and underground installations.

Assured quality

Double-See pipes and fittings are 100% factory-assembled. They offer GF quality as well as field and factory engineering support.
