SKU CH-PK81-QTY79

Protects pressure gauges from steam with a seamless iron pigtail rated to 500 psi

  • TypeElectronic
  • Handles steam installations with 500 psi maximum internal pressure
  • 600 psi burst pressure provides safety margin
  • 1/4 in NPT connection fits standard fittings
  • Seamless iron construction resists leaks
  • 5 11/16 in pigtail tube allows flexible routing

Steam installation siphon

This pressure gauge siphon is built for steam installations where the gauge must be protected from direct steam contact. The iron pigtail condenses steam before it reaches the instrument. It is intended for technicians and plant operators who need reliable gauge readings in high-temperature steam service.

Pressure and connection limits

The siphon handles a maximum internal pressure of 500 psi and a burst pressure of 600 psi. Its connection is a 1/4 inch NPT thread, so it fits gauges and piping with the same thread size and rating. The seamless iron construction provides the stated pressure capacity without welded joints.

Replaces worn or missing pigtails

This unit replaces a damaged, corroded or missing pigtail siphon on an existing steam gauge assembly. The upgrade is worth it when the original siphon leaks, shows scale buildup or has been removed during maintenance. It is not suited for applications that require a corrosion-resistant coating or a different connection standard.

Questions about this item

Should I choose the pigtail or a different tube style for my steam gauge?

The pigtail tube style creates a water seal that protects the gauge from direct steam heat and pressure surges.

What does the 500 psi maximum internal pressure mean when the siphon is installed on a live steam line?

It means the siphon is rated for continuous service up to 500 psi; the 600 psi burst pressure provides a safety margin above normal operating pressure.

How does the 1/4 in NPT connection limit the pipe sizes I can use?

The 1/4 in NPT male threads only mate with 1/4 in NPT female ports; you cannot connect it directly to larger or smaller pipe threads without an adapter.
