  • 1/4 in NPT connection fits standard fittings
  • 5 11/16 in pigtail tube suits tight installs
  • Brass construction resists corrosion in steam service

Brass Siphon for Steam Installations

This brass siphon protects pressure gauges in steam installations by condensing steam before it reaches the instrument. It handles a working pressure of 250 psi and a burst pressure of 300 psi. The seamless construction uses red brass material with a 1/4 inch NPT connection.

Pigtail Loop for Thermal Protection

The 5 11/16 inch pigtail tube creates a water seal that prevents live steam from contacting the gauge internals. It threads directly into a 1/4 inch NPT port on the gauge or piping without additional fittings. The brass body resists corrosion in typical steam service environments.

Upgrade from Unprotected Gauge Connections

Install this siphon when replacing a gauge that failed due to heat exposure or when adding instrumentation to a new steam line. It is not suited for systems exceeding 250 psi working pressure or for applications requiring certified corrosion-resistant ratings. The one-year manufacturer warranty covers defects in material and workmanship.

Questions about this item

At what pressure does the siphon risk bursting during sustained steam service?

The brass siphon is rated for a burst pressure of 300 psi, well above its 250 psi working limit.

How hot does the brass tube get when steam flows through it all day?

The pigtail tube acts as a steam trap, condensing vapour so the gauge stays cooler than the line temperature.

What thread must my gauge or piping have to connect this 1/4 in NPT siphon?

Both ends use 1/4 in NPT threads, so the mating gauge or pipe needs matching NPT connections.
