Victaulic Introduces the Only Direct Groove Two-Piece Coupling for Large Diameter Piping Systems

Two-piece coupling design makes it faster and easier to install, maintain and retrofit piping systems up to 60" in diameter.

EASTON, PA (November 5, 2009) - Victaulic, the world's leading manufacturer of mechanical pipe joining systems, today announced the extension of its line of patented Advanced Groove System (AGS) couplings for faster and easier installation of large-diameter piping systems. The line extension means Victaulic now offers rigid and flexible couplings with the AGS technology for pipe sizes up to 60 inches/1,525 millimeters in diameter for HVAC, mining, water and wastewater and industrial applications.

A typical large-diameter joint that requires several hours to weld can be installed easily in less than an hour using Victaulic AGS couplings. With a two-piece housing and a wedge-shaped groove that delivers pressure ratings up to 350 psi/2,400 kPa, depending on the pipe size and wall thickness, Victaulic AGS couplings offer exceptional assembly speed and reliability. Until now, joining methods for larger size piping systems required multiple housings to achieve the same results. Victaulic is the only manufacturer to offer a two-piece housing for couplings in this size range.

"When we designed AGS, our customers set the criteria. They wanted a stronger, more reliable and easier-to-install coupling, so we introduced AGS for 14-24-inch piping systems. Now, we have applied the same criteria to our 26-60-inch couplings so that our customers with larger piping needs can experience the AGS advantage," said Wayne Biery, Product Manager- Large Systems for Victaulic.

To further simplify installation, the new larger size AGS coupling housings feature lifting lugs for added convenience when lifting individual housings. AGS couplings also provide a union at every joint for easy access to the piping system for scheduled and unscheduled maintenance and system retrofits. In addition, the coupling also provides visual confirmation of proper assembly-assembly is complete when housings are metal-to-metal and torque requirements have been met-an added benefit that helps to ensure proper assembly.

Available in diameters of 14-60″/350-1,525 mm, Style W07 and W77 AGS couplings are equipped with plated bolts and nuts and a Victaulic FlushSeal® gasket in Grade "E" EPDM, Grade "T" nitrile or Grade "L" silicone gaskets.

Style W07 and W77 AGS couplings are ideal for use in HVAC, mining, industrial water distribution systems, as well as water and wastewater lines.
