Choosing a ball valve for a piping system comes down to connection type, bore size, and material. A quarter-turn valve should give you full flow or complete shutoff without seizing or leaking. With an option priced at $12.09, the key is deciding whether its specifications fit the water, oil, or gas line you're working on. The right choice depends on how much pressure, temperature, and media exposure the valve will see.

This manual lever valve uses a 2-piece body with a 316 stainless steel ball, PTFE seals, and a heavy-duty blue vinyl handle. It has a full-port bore for minimal flow restriction and is rated at 1000 WOG (water, oil, gas) with a temperature range of -60°F to 450°F. The 1-1/4\" NPT female threads connect to standard tapered pipe, making it a straightforward choice for existing threaded systems in this size. The manual lever gives you clear on/off control, and the stainless steel construction resists corrosion for long service.

Quick Verdict

For straightforward shutoff, this full-port ball valve offers a balanced combination of material quality and price at $12.09. Its full-port design keeps flow restriction low, making it a practical choice for water, oil, and gas service. If you need a dependable valve for a simple shutoff task, it delivers the essentials without complicating the setup.

Who It Suits

This valve suits maintenance work in industrial components, plumbing repairs, and light liquid or gas lines where dependable shutoff is needed. Its compact footprint and straightforward operation make it a practical choice for technicians who want a reliable shutoff valve without extra complexity. If your application involves periodic adjustments rather than continuous throttling, this valve fits the bill.

What Stands Out

The 316 stainless steel body and ball give this valve a strong corrosion-resistant foundation, while the PTFE seals add a layer of chemical resistance that helps prolong service life. The heavy-duty lever handle with blue vinyl insulation provides a secure, comfortable grip, even when wearing gloves.

Meaningful Trade-Offs

The main constraints are the 1-1/4\" NPT female threads and the manual lever operation. If your system uses a different connection style, you may need an adapter. Also confirm your media and operating temperature stay within the 1000 WOG and -60°F to 450°F specifications. The 2-piece design isn't a union, so inline maintenance may require more effort. And because it's a manual valve, it won't support automated or remote shutoff. For most straightforward shutoff jobs, these limits are acceptable, but they're worth noting before purchase.

Bottom Line

If you're after a durable shutoff valve for a simple job, this model is a dependable pick. Confirm your media and temperature range match the rating, and you'll have a straightforward flow control solution.
