The GIACOMINI A80 and A80P cap and chain cover and protect male outlet threads on valves and hydrants and prevent deposit of foreign material. The A80 is forged brass rated 300 psi; the A80P is ABS with a gasket, rated 100 psi. The chain keeps the cap attached to the valve when removed.
In short
- A80: forged brass, 300 psi, sizes 1-1/2″, 2-1/2″ and 3″.
- A80P: ABS with gasket, 100 psi, sizes 1-1/2″ and 2-1/2″.
- A80 with pin or rocker lugs; A80P with rocker lugs.
- Female thread fitting the valve’s male outlet.
Why the cap matters
An exposed hose outlet thread is open to knocks, paint and dust, and any damage stops the hose coupling on in a fire. The cap protects the thread and keeps it clean, and its presence is part of the periodic hose valve inspection.

The critical point: match thread and size
The cap thread must match the valve outlet thread (the local fire department hose thread). Choose the brass A80 where the cap may see line pressure, as the A80P is rated only 100 psi.
Installation steps
- Fix the chain end to the valve.
- Screw the cap on hand-tight until seated, without overtightening that would hinder removal.
Common mistakes
- Wrench-tightening the cap so it is hard to remove in a fire.
- Painting over the cap and valve so it sticks to the thread.
- A cap with a different thread from the outlet.
Inspection and maintenance
At periodic inspection, check the cap is present, sound and removable by hand; replace missing or damaged caps.

FAQ
Brass or plastic?
Brass is tougher and rated 300 psi; plastic is lighter and more economical, rated 100 psi. The project specification decides.
