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 Rapidrop type 1NR reducing coiuplings are pressure rated to 300psi and can be used to reduce pipe size without having to use a grooved reducer. They can be used with standard and thin walled pipes.
