Isolation Valve Adapter Pair for Body B

This Legend Valve 800-875VF kit supplies two 1" FPT isolation valve adapters designed for Body B connections. The pair lets installers isolate flow on each side of a component without shutting down the whole system. It is intended for hydronic heating and cooling circuits where serviceable shut-off points are required.

Threaded FPT Integration

Each adapter uses a 1" female pipe thread to join directly to matching male-threaded pipe or fittings. The connection frees the installer from soldering or pressing at the valve body, reducing installation time on retrofit or new-build jobs. No special tools beyond standard pipe wrenches are needed to make the joint.

Replaces Separate Valve and Union Assemblies

The combined valve-and-adapter design replaces the traditional practice of threading a separate ball valve onto a union or coupling. The jump is worthwhile when a compact, factory-aligned shut-off point cuts labour and potential leak paths on Body B manifolds or branch lines. California Proposition 65 warnings apply.

Questions about this item

What is the first limitation that appears during sustained use of the 800-875VF isolation valve adapter?

The adapter contains a chemical known to the State of California to cause cancer and birth defects under Proposition 65, which is the primary regulatory limitation noted.

How much noise, heat, or power does the 800-875VF adapter generate when running all day?

As a passive brass fitting with no moving parts or electrical components, the adapter produces no noise, negligible heat, and consumes no power during continuous operation.

What existing plumbing components must I already own for the 1" FPT LegendConnect pair to work?

You need a compatible Body B valve assembly with matching 1" FNPT connections to accept these LegendConnect adapters as a pair.
