CLSR2U Fuel Shut Off Valve – 1/4-Inch In-Line Gas Valve for Mowers & Small Engines (4-Pack)

Smart fuel control for small engines

CLSR2U’s inline fuel shut off valve delivers simple, rugged control over fuel flow for a wide range of small engines that use a 1/4 inch inner diameter fuel line. Whether you’re prepping equipment for storage, performing routine maintenance, or aiming for an easier startup, this compact valve is designed to fit in-line without fuss. Its straightforward design focuses on reliability in real-world shed, shop, and yard tasks, helping you manage fuel with confidence.

Designed to work with a broad selection of machines—from riding lawn mowers to pressure washers and snowblowers—the valve supports many popular brands and models. Expect compatibility with setups from Craftsman, Cub Cadet, John Deere, Lawn-Boy, Troy-Bilt, Toro, Murray, and other engines that use a 1/4" fuel line. This versatility means you can stock up once and reuse the same valve across multiple small engines you own or service.

Carb protection and seasonal storage

One practical benefit is the ability to cut fuel supply and let the carburetor run dry, which can help minimize fuel gunk and residue when equipment sits unused. This simple step can make seasonal storage more convenient and can reduce maintenance tasks when you’re ready to bring equipment back into service.

Maintenance-friendly design

In addition to seasonal storage, the valve supports everyday maintenance activities such as changing fuel filters or draining the carburetor during repairs. By providing a quick, controllable shut-off point, it helps you work with fuel lines more cleanly and with less risk of spills or leaks.

Easy installation and a complete kit

Installation is straightforward: cut the fuel line and attach the valve ends using the included hose clamps. The package contains four shut-off valves plus eight hose clamps, so you have enough hardware to outfit multiple connections or engines at once. Expect a snug, secure fit with common small-engine fuel lines.

What you get

• 4 CLSR2U shut-off valves
• 8 hose clamps for secure connections

Note: As with any fuel hardware, performance depends on your specific engine model and fuel system. This valve is designed to offer a practical option for managing fuel flow and maintenance tasks rather than a guaranteed outcome across all applications.
