The Febco 880 and 880V are reduced pressure assemblies (RPA). They were available in 2 1/2″-10″ sizes and were produced from 1993-2014. Their bodies were made of epoxy coated ductile iron. The 880 was an “N” shaped device while the 880V utilized a grooved coupling in the body for either an “N” pattern or “Z” pattern installation but the internal components are the same. A lead free version was introduced in 2011. The RV housing of the 880 and 880V is bronze and the LF880V is epoxy coated ductile iron. The parts do not interchange.
