Febco 905111 rubber parts kit for 3/4 to 1 1/4 in assembly

Febco 905111 rubber parts kit

The Febco 905111 kit supplies replacement rubber components for reduced pressure zone assemblies sized from 3/4 in to 1 1/4 in. It is intended for plumbers and facility managers who maintain backflow preventers and need a single package of seals.

Build quality and daily implications

The kit includes two RV O-rings, three bushings, covers, a diaphragm, an O-ring, an RV seat disc and a seat O-ring, all made of rubber suited to potable water service. Having every seal in one box reduces downtime during scheduled rebuilds and eliminates the need to source individual parts from multiple bins.

Practical limits of the assembly standard

This parts kit only fits reduced pressure zone assemblies within the stated size range and does not adapt to other valve types or larger diameters. Installers must verify the exact model before ordering because the kit cannot be used on double-check or pressure vacuum breaker bodies.
