860 / LF860 large-body service parts
Double check / reduced pressure large-body service parts
FEBCO 860 large-body service references change across 2 1/2–3, 4, 6, and 8–10 inch bands. This record maintains those boundaries and does not mix 860 with 880V or detector variants.
The same manual contains 860 and 880V information. This page shows only 860 references. Verify the full label, assembly type, and size before ordering or opening the body.

Identity check
Confirm this model before ordering.
Similar-looking assemblies can use different internals. A search result or pipe size alone is not enough.
- 01
Confirm that the body is 860/LF860 rather than an 880V, LF866, or other related FEBCO large-body assembly.
- 02
The manufacturer publishes different part numbers by size for check replacement and complete rubber service.
- 03
A relief-valve service kit is a separate scope from complete rubber or check replacement.
Before return to service
A matching kit is not a passed assembly.
Stop for body damage. Cracks, distortion, severe corrosion, or freeze damage can move the job from internal service to replacement.
Test after repair. Where the assembly is regulated, the governing utility or authority decides tester approval, reporting, and deadlines.
Use the current instructions. Part references can change. Confirm availability and supersession with the manufacturer or an authorized supplier.
