Rapidrop Grooved couplings and fittings are used in the assembly of grooved piping systems. They are available in painted and galvanised finishes and are FM, UL, VdS, LPCB and CNBOP approved. The standard duty rigid couplings are pressure rated up to 500psi (depending on size) and are used where no movement in the system pipework is expected.
