Lingmfg Angle Valve, 1/2-inch PEX-B Crimp
Product description
What to know
If you need a local shutoff for a toilet or sink supply, this angle valve is built around a specific connection pairing rather than a general-purpose plumbing setup. Its inlet is a 1/2-inch PEX-B crimp connection, and its outlet is 3/8-inch compression, so the key buying question is whether those sizes and connection types match the pipes and hose in your installation.
The listing includes 10 valves, which may suit a multi-fixture project or keeping matching replacements on hand. It also describes the valves as compatible with 1/2-inch PEX-A, PEX-B, and PEX-C pipe, and with a 1/2-inch stainless-steel clamp or copper crimp ring. Keep in mind that the outlet is specifically 3/8-inch compression, it won’t directly match a hose or fitting with a different connection.
How to use it
The valve is intended to sit between a 1/2-inch PEX supply line and a toilet or sink hose with a 3/8-inch compression connection. For example, during a bathroom fixture replacement, it can provide a shutoff at the fixture rather than requiring you to rely only on a more distant supply shutoff. The product is described as easy to install, but the right crimp method and a matching hose connection still matter.
It suits you if your project calls for this exact inlet-and-outlet combination and you want several valves together. If your plumbing uses a different outlet size or connection style, a valve made for that setup is the more direct choice.
Practical tips
Before choosing it, compare the valve’s listed connections with both ends of the plumbing run: 1/2-inch PEX at the inlet and 3/8-inch compression at the outlet. The listing names stainless-steel clamps and copper crimp rings as compatible fastening options, but it does not specify which one is included, so don’t assume the package contains installation hardware beyond the valves.
The product is described as lead-free, and the valves are sold as a 10-piece set. That quantity is useful when replacing several shutoffs in one project, though it may be more than needed for a single fixture. A different purchase format may make more sense if you only need one valve. The listing also identifies an ISO-certified factory, but gives no further certification details for evaluating the certification itself.
Before you decide
What does the inlet connect to? The listed inlet is a 1/2-inch PEX-B crimp connection. The description also says it suits 1/2-inch PEX-A, PEX-B, and PEX-C pipe.
What does the outlet fit? It is a 3/8-inch compression outlet for a toilet or sink hose with a matching 3/8-inch compression connection.
How many valves are included? The product description says the set includes 10 shutoff valves.
When it makes sense
This set makes the most sense when you have several fixtures to equip or replace and each installation uses the stated 1/2-inch PEX inlet and 3/8-inch compression outlet. Choosing a valve with a different connection is the safer route if your existing supply line or hose doesn’t match those specifications. It might not be a great match if you only need one valve or need a different outlet size, the 10-piece quantity and fixed connection pairing are the main tradeoffs to weigh.
