Product Identity

The Jomar Valve 101-403 is a new manual two-way brass ball valve designed for gas service in residential or light-commercial plumbing systems. It features a straight inline body with 1/2 inch FNPT connections and a locking tee handle for secure operation.

Pressure and Vacuum Limits

The valve carries a maximum operating pressure of 600 psi and a vacuum service rating of 29 in Hg. It has no steam pressure rating and its combustible gas pressure limit is not rated, so it must not be used in steam lines or applications exceeding the stated pressure boundary.

Deciding Specification

The 1/2 inch nominal size and FNPT thread type determine whether this valve fits the piping system; mismatched thread standards or pipe diameters will prevent installation. Buyers needing a different connection size, a non-locking handle, or a full-port flow path cannot use this model.

Questions about this item

Should I pick the 101-403 or another size for a 1/2-inch gas line?

The 101-403 is built for a 1/2-inch nominal pipe size with FNPT threads; match it to your existing 1/2-inch piping and gas type.

What does the 600 psi rating mean when the valve is installed on a residential gas system?

It certifies the valve body and seals for up to 600 psi operating pressure, far above typical residential supply pressures.

How does the FNPT connection affect the pressure the valve can actually hold?

The 1/2-inch FNPT threads seal with pipe dope or tape; the 600 psi limit applies to the valve assembly when the joint is made up correctly.
