SKU CH-4BNM-CKP46

Connects 1-inch press pipe to male NPT threads at a 90-degree angle for plumbing systems

  • 90° elbow routes pipe around tight corners
  • Press x MNPT ends join press and threaded systems

Application fit

The Legend Valve 450-143P is a 1 inch 90 degree elbow press x MNPT valve designed for plumbing installations that require a right-angle transition between press and male pipe threads. It suits installers working on water or hydronic systems where a compact directional change is needed.

Upgrade context

This fitting replaces a separate elbow and adapter combination, reducing joint count and potential leak paths. The jump is worth it when a single-piece 90 degree connection simplifies assembly in tight spaces or when local code favours fewer mechanical joints.

Build integration

The press end connects with compatible press tools and the MNPT end mates with standard threaded components, so no special fittings are required beyond the press system itself. It frees up space by combining two connections into one compact body and eliminates the need for an extra nipple or coupling in the run.

Questions about this item

What size copper pipe fits the press end of the 1 inch 90 degree elbow press x MNPT valve?

The press connection is sized for 1 inch copper tubing; ensure the tube is clean, deburred and inserted to the full depth mark before pressing.

Which press tool and jaw set are required to install the 450-143P elbow, and what is the common mistake?

Use a compatible press tool with a 1 inch jaw; the frequent error is not pushing the tube fully to the stop before actuating the tool.

How often should the press seal on this 90 degree elbow be inspected or replaced?

Inspect the joint annually for leaks or corrosion; the press seal is permanent and only replaced if the fitting is removed or damaged.
