They are recommended for industrial and commercial heating applications with 1/4″ NPT pipe connections, suitable for a range of gasses including natural gas, propane, butane, air, and inert gasses. The set point can be easily adjusted in the field using an integrated scale, with a test nipple provided for set point verification.
