DUNGS SBO / CO - Gas Orifices (US/CA)

The DUNGS SBO / CO Gas Orifice is a low-cost flow metering device used to accurately set burner air and gas flow for optimum combustion efficiency in industrial gas systems. It is suitable for applications requiring precise gas measurement, with SBO models for 1/2–2" NPT and CO models for 2 1/2–24" pipe sizes.

The DUNGS SBO (Screwed Brass Orifice) is available in 1/2–2" NPT sizes, rated at 250 PSI and up to 300 °F, with 1/8" NPT pressure taps and ±1% accuracy. The CO (Carbon Steel Orifice) covers 2 1/2–24" sizes, also rated at 250 PSI. Both include metal identification tags and brass hex-head screws for plugging unused taps.

You can source DUNGS SBO / CO Gas Orifices through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on these DUNGS flow metering devices, which are available to order for industrial burner applications.

Installation must be performed by a trained specialist with gas pressure and power off, and no open flame. Follow DUNGS instructions for proper straight pipe lengths upstream and downstream. After installation, perform a leakage test. Ensure the orifice rating (250 PSI, up to 300 °F for SBO) matches your application.
