4 Inch (NPS 4") Flexible Grooved Coupling - Ductile Iron, UL/FM Certified for 4.5" OD Fire Sprinkler Pipes (Wet/Dry Systems), Moderate Pressure 2.5Mpa/360 PSI (DN100(NPS 4"))
Description
This kind of coupling is designed for pipes bearing moderate pressure. It allows controlled angular, linear, and rotational movement at each joint and provides the added advantages of expansion, contraction, and deflection. This is useful to accommodate uneven laying surfaces, and movement from thermal changes, settling, seismic effects, or other causes. Flexible couplings can be used in fire protection systems, feedwater, natural gas systems, etc.
