  • Quarter-turn operation speeds shut-off

  • T-565 rated for heating and cooling systems
  • Legend Valve brand assures professional-grade construction

Product Identity

The Legend Valve 111-205 is a quarter-turn ball valve designed for oil tank installations. It connects a 1/2 inch male NPT fitting to a 3/8 inch male NPT fitting using the T-565 pattern.

Buyer Fit

This valve suits technicians and RV owners who need a compact, positive shut-off between two male pipe threads of different sizes. It is not for systems that require a full-port flow path, a locking handle, or a connection size other than 1/2 MNPT by 3/8 MNPT.

Deciding Specification

The defining detail is the 1/2 MNPT by 3/8 MNPT thread combination in a T-565 quarter-turn body. Match those exact endpoints to the tank and line you are joining; a different thread pair or a multi-turn design will not fit the same application.

Highlights

  • Quarter-turn operation speeds shut-off
  • 1/2 MNPT by 3/8 MNPT fits standard oil-tank threads
  • T-565 rated for heating and cooling systems
  • Legend Valve brand assures professional-grade construction
  • New condition guarantees full factory performance

Questions about this item

What thread sizes are on the inlet and outlet of the 111-205 valve?

The valve has a 1/2 MNPT male thread on one end and a 3/8 MNPT male thread on the other end.

Which way should the handle point when installing the T-565 ball valve?

Install the valve so the handle aligns with the pipe when open and sits perpendicular when closed, confirming the quarter-turn action.

How often should the T-565 valve be checked or replaced in an oil tank system?

Inspect the valve annually for leaks or stiff operation; replace it if the ball or seals show wear or if the handle no longer turns smoothly.
