The new LOKX System Ductile Iron Fitting from GF Piping Systems features an internal self-restraining gasket that eliminates pipe-to-pipe and pipe-to-fitting separation, even at high pressures. The push-on style fitting eliminates the need for any bolts or external restraints, saving up to 80% in installation time and labor costs. Engineered with a deep bell design, the LOKX system has deflection capabilities of up to a total of 10 degrees in any direction (5 degrees deflection per bell). This flexibility allows for extreme ground movement, making it suitable for seismic applications. The leak-resistant LOKX System can be used for a variety of buried applications in water and wastewater, seismic areas, corrosive regions, coastal areas with brackish soils, and horizontal directional drilling.
