For anyone who already has this catalog's 1-inch Hunter PGV (or any valve or pipe of that diameter) and needs to step down to 3/4 inch to connect it to the rest of the system, without replacing the whole install.
It's a small threaded connector shaped like a nut (a "bushing") that solves one specific problem: one end has a bigger thread (1 inch) and the other a smaller one (3/4 inch), so it joins two parts that otherwise wouldn't screw into each other — like a travel plug adapter that fits a bigger plug into a smaller outlet, except here it's for pressurized water instead of electricity.
Your house has a 1-inch valve like this catalog's Hunter PGV (maybe because the original installer chose that size for more flow), but the rest of the system — pipe, fittings, the drip kit — is all 3/4 inch, the standard size. This bushing is the piece that joins both diameters without replacing the whole valve or the piping.
An irrigation contractor who maintains systems from different eras and brands runs into this exact mismatch all the time, between an old 1-inch valve and today's parts, almost all of them 3/4 inch. Keeping a couple of these brass bushings in the toolbox avoids a separate hardware-store trip for every mixed-size install.
Compared to a generic PVC bushing that costs a dollar less, brass handles more heat (up to 250°F versus standard PVC's 140°F) and won't crack if the joint needs to come apart more than once for maintenance — a part that costs a few dollars but snaps from over-tightening ends up costing more, in time and in the water lost before you notice the leak.
TAISHER Brass Reducer Bushing 1" to 3/4" — Threaded Adapter for Irrigation Valves (2-Pack)

This is the missing adapter between this catalog's 1-inch Hunter PGV and the rest of a 3/4-inch system: a 1-inch male thread that screws into the valve's female port, and a 3/4-inch female thread on the other end to receive the smaller-diameter pipe or fitting. Unlike the generic loose PVC bushings sold for this, this one is solid brass — it handles up to 250°F and 120 PSI (standard PVC tops out at 140°F) and won't crack from over-tightening with a wrench, something that does happen to a cheap plastic bushing on a joint that may get taken apart again for maintenance. It ships as a 2-pack; 4.7 stars and 1,068 reviews, one of the best-rated adapters of this size on Amazon. Real limitation: at the time of this check only 1 unit was left in stock within the qualified offer (buy box with an active purchase button) — if it's unavailable when you go to buy, it's the same standard plumbing part (a 1" MPT x 3/4" FPT threaded reducer bushing) sold in brass or PVC at any irrigation supply store.

Field glossary
So you can use the right vocabulary with a customer, a supplier, or a manual.
With over 2,400 reviews, it's by far the best-selling valve in this category — which also means more spare parts and installation guides are available if something fails. 3/4" FPT thread, normally closed like most residential valves, and compatible with any 24V AC controller, not just Orbit's own.
Important: this is NOT a complete valve, it's the replacement solenoid (the coil) for Irritrol valves in the 2400, 2500, 2600, and 700 series. It makes sense to buy this if your current valve stopped opening or closing but the valve body is still in good shape — replacing just the solenoid is cheaper than swapping the whole valve.
Unlike the in-line Orbit 57280 valve in this ranking (which goes underground), this is an 'anti-siphon' valve: it installs above ground level, typically screwed directly onto a spigot, with a built-in vacuum breaker — required by code in many areas when a valve sits near a potable water source. 3/4" thread, standard 24V AC, compatible with any controller. Nearly 900 bought in the past month.
