Product Identity

The Legend Valve 800-876S Adapter is a 1-1/4 inch sweat connection pair designed for Body B radiator components. It serves HVAC installers and maintenance technicians who need to join copper piping to compatible boiler or radiator bodies using a sweat fitting method.

Installation Check

Verify that the existing system uses Body B components and requires a 1-1/4 inch sweat connection before ordering. Confirm the piping material is suitable for sweat soldering and that local codes permit this joining method. Note the California Proposition 65 warnings regarding chemicals known to cause cancer and reproductive harm.

Suitability

This adapter pair suits professionals completing or repairing hydronic heating installations with matching Body B specifications. It is not for installers working with different body styles, alternative connection types such as press or threaded fittings, or pipe diameters other than 1-1/4 inch.
