Victaulic, the world's leading manufacturer of mechanical pipe-joining systems, introduces the Style 177N QuickVic® Installation-Ready™ coupling. The coupling's design eliminates loose parts, ensures consistent joint reliability and provides substantial gains in installation productivity. The Style 177N flexible coupling was specifically designed to withstand the rigors of mining environments and is ideal for utility and process piping applications in plants and underground metal and coal mines.

The Style 177N QuickVic coupling can be installed up to ten times faster than other pipe-joining methods and twice as fast as existing grooved couplings. Featuring Installation-Ready technology, the Style 177N does not require disassembly prior to installation, eliminating loose parts. The coupling is pushed onto a grooved pipe-end as a fully assembled unit, connected to a second grooved pipe-end, and tightened using standard hand tools or an impact wrench. The gasket’s integral central leg serves as a pipe stop, ensuring full pipe insertion, and metal-to-metal bolt-pad contact provides visual confirmation of proper assembly.

The Style 177N is a flexible coupling that permits a limited amount of linear and angular movement at the pipe joint to accommodate expansion, contraction and deflection.

The Style 177N is available in 2- to 6-inch sizes (50 to 150 millimeters) and accommodates pressures ranging from full vacuum (29.9 inches Hg/760 millimeters Hg) up to 1,000 psi (6,900 kPa). The coupling is supplied with a grade “EHP” EPDM gasket for water services or grade “T” nitrile gasket for air services.

The Style 177N is an addition to the Victaulic Installation-Ready coupling family, which includes the Style 107 rigid coupling. Installation-Ready couplings join standard roll-grooved and cut-grooved steel pipe.
