The 3/8" female SAE connector on the # 37207-31255 will be compatible. However, SAE and NPT are not interchangeable since they are threaded differently. SAE fittings are straight and use an O-ring for the seal. NPT threads are tapered to create the seal without an O-ring. Since you have a flare fitting it actually wouldn't be NPT but SAE so using it with the female SAE connector won't be an issue.
