Rw Beckett 12810 Fusible Link Inline Valve 3/8 Inch Fpt

Product Description

The RW BECKETT 12810 is a fusible link inline safety valve designed to shut off fuel oil flow from the storage tank in the event of a fire. Rated for a maximum working pressure of 10 psi, the valve features high-quality brass construction with a double seal washer and o-ring stem system using Viton-equivalent materials. It is compatible with No. 2 fuel oil and kerosene, making it well suited to residential oil-fired heating systems. The valve body is embossed with a directional arrow to confirm correct flow orientation during installation. A built-in manual handwheel allows it to double as a service valve.

This valve is intended for use in residential oil heating installations where local codes and NFPA 31 require a fusible link shutoff between the oil storage tank and the burner. The 3/8-inch FPT by 3/8-inch FPT straight inline configuration fits common fuel-line connections in typical boiler and furnace oil supply runs. Licensed oil heat technicians and plumbers routinely specify this type of valve during new installations, equipment changeouts, and code-compliance upgrades.

Installation Notes

Installation should be performed by a licensed oil heat technician or plumber in accordance with NFPA 31 and applicable local codes.

Confirm the embossed flow arrow on the valve body aligns with the direction of fuel flow toward the burner. Inspect thread connections for proper sealing with approved thread sealant rated for fuel oil service before returning the system to operation.
