Quick Take
Choosing an industrial valve often comes down to three things: pipe size, how many valves you need, and what you want to spend. These four ball valves cover sizes from 3/8 inch to 1-1/4 inch, with listed prices from $12.09 to $23.98. Two are sold as two-packs, and two are single valves.

Decision Matrix
- If the line is 3/8 inch, the ANIX 3/8-inch ball valve is the only listing at that diameter.
- If you need two 1-inch valves, the 1-inch two-pack is the direct fit.
- If you need two 3/4-inch valves, the 3/4-inch two-pack is the direct fit.
- If you need the largest pipe size in this group, the 1-1/4-inch single valve is the one to check.
Product Notes
3/8-Inch ANIX 316 Stainless Full-Port Ball Valve
At 3/8 inch, this ANIX valve is the smallest listing in the group, and its threaded NPT body is a match for compact stainless piping. The listed media range covers air, fuel, oil, wastewater, and water, so it is positioned as a multi-service option rather than a water-only valve. One limitation is the price: it is the highest listed price in this comparison, and the package contains a single valve. If your project needs a small-diameter full-port valve and you are set on 316 stainless steel, this is the one to pair with your line.
1-Inch 316 Stainless Full-Port Two-Pack
For a 1-inch line, this two-pack gives you two 316 stainless steel full-port ball valves with NPT threading. That works out to a lower per-valve cost than either single-valve listing in this group, though the 1-inch size will not help if your pipes are 3/4 inch or 1-1/4 inch. The included pair is a practical way to cover two shutoff points or keep a spare on hand. The main limitation is the pack size: you are buying two valves, so if you only need one, you will have an extra. It is described for manual lever operation, which is what most ball valve installations expect.
3/4-Inch 316 Stainless Full-Port Two-Pack
The 3/4-inch two-pack comes in just below the 1-inch two-pack in price, and it offers the same two-valve convenience for 3/4-inch NPT piping. Both valves are 316 stainless steel with a full-port bore, and the set is intended for manual operation. If your system uses 3/4-inch lines, this is a straightforward way to have two isolation points without buying valves one at a time. The limitation is the fixed quantity: you get two valves whether you need one or not. And because this is a 3/4-inch model, it will not work on a 1-inch or 1-1/4-inch line. For someone who needs exactly two replacement valves at this size, the pack saves a second order.
1-1/4-Inch 316 Stainless Full-Port Ball Valve
The 1-1/4-inch valve is the lowest listed price in this comparison, and it is also the largest pipe size here. If your system runs on 1-1/4-inch NPT fittings, this single 316 stainless steel full-port valve gives you the largest connection size of the four. The limitation is the same as any single-valve purchase: one valve is what you get, so if you need to replace multiple valves, you will need to order more than one. The smaller 1-inch and 3/4-inch two-packs are cheaper per valve, but they will not fit a 1-1/4-inch line. For a one-for-one swap at this size, the price is the main reason to consider it.
Final Recommendation
Match the valve to the pipe size first. For a 3/8-inch line, the ANIX compact valve is the only listing at that diameter, and its broader media list makes it worth the top-of-range price. For 1-inch piping, the 1-inch two-pack is the practical buy if you need two valves. For 3/4-inch piping, the 3/4-inch two-pack covers two points. For the largest pipe size and the lowest listed price in one package, the 1-1/4-inch single valve is the one. If you only need one valve at 1 inch or 3/4 inch, you may end up with a spare in the two-pack; the single 1-1/4-inch valve avoids that but only fits a bigger line.
