Legend Valve 800-877M Adapter Pair

This Legend Valve 800-877M adapter pair provides two 1-1/2 inch MNPT fittings designed for Body C connections. It suits HVAC installers and maintenance technicians who need to join piping to a compatible boiler or radiator body. The components arrive new and ready for professional assembly.

Replaces worn or mismatched Body C fittings

Use this pair when existing Body C adapters are damaged, corroded or have incorrect thread types. The upgrade is worth it when a secure MNPT transition is required to restore a leak-free seal in the hydronic circuit. California Proposition 65 warnings apply to chemicals in the product.

Verify Body C compatibility and thread requirement

Before ordering, confirm that the target equipment uses a Body C interface and requires 1-1/2 inch male NPT threads. Check that your piping layout matches this specific connection style. No other sizes or thread standards are included in this package.

Questions about this item

What thread size does the 800-877M adapter need to connect to?

The adapter has a 1-1/2" male NPT thread that screws into a matching female NPT port on the Body C fitting.

How do I install the LegendConnect adapter pair without causing leaks?

Apply thread sealant to the male NPT threads, hand-tighten into the Body C ports, then finish with a wrench — the step often missed is using sealant on every thread.

When should I replace the 800-877M adapter pair in a hydronic system?

Replace them if you see corrosion, seepage at the threads, or during any boiler service that exposes the Body C connections.
