The Fireguard FG08 series breeching inlet valves are BSI-certified dry riser inlet assemblies fully compliant with BS5041 Part 3, designed to provide ground-level water supply connection points for dry rising main systems. When positioned as close as possible to the rising main, they minimise pressure loss — a critical consideration in high-rise building firefighting operations where the fire brigade charges the system in an emergency.

Two Configurations for Different Flow Requirements

The FG08-202-00 2-way inlet breeching provides two 2½” instantaneous male BS336 non-return valve inlets with a 4″ outlet flange, suited to buildings with moderate riser flow requirements.

The FG08-203-00 4-way inlet breeching provides four 2½” instantaneous male non-return valve inlets with a 6″ outlet flange, delivering higher flow capacity for larger or taller high-rise buildings.

Both models are supplied complete with a 1″ drain valve and plastic blank caps for inlet protection when not in use.

Robust Construction
Bodies are cast from ductile iron to BS EN 1563:1997, with universal PN16 flange copper alloy inlets to BS EN 12163:1998 and male instantaneous copper alloy outlets to BS336/BS EN 12163:1998 — ensuring long-term durability and compatibility across all standard UK fire brigade connections.
