  • UL-Listed and FM-Approved
  • Rigid couplings used in straight runs should be supported similar to welded or flanged piping. Refer to: ANSI B31.1, ANSI B31.9, NFPA 13.
  • Rigid couplings do not provide longitudinal movement. However, a gap exists between pipe ends and should be considered when calculating axial displacement.
  • Rigid couplings are recommended in areas of concentrated weight and where flexibility is not desired, to hold plumb and pitch.
  • Where large concentrations of weight occur, such as in mechanical rooms and when installing valves, rigid couplings are highly recommended.
  • When presetting power nut-drivers, the following torque should not be exceeded. Excessive tightening of the nuts could result in joint failure. (Values Lbs-Ft.) 3/8″= 50-59 ; 1/2″=81-92 ; 5/8″= 147-190; 3/4″=177-179; 7/8″=202-221.
  • Coating options: Epoxy, Paint, Dacromet, Hot-Dip Galvanized.
