Brass steam trap with offset ports and air vent

BELL AND GOSSETT

BELL AND GOSSETT 17C-S-3-25 hvac control

SKU CH-PC33-S07B0

Brass steam trap with air vent handles 162 lb/hr condensate at 25 psi for convectors and radiators

  • Handles 162 lb/hr condensate for efficient steam systems
  • Rated to 25 psi and 353 °F for demanding applications
  • Brass body resists corrosion in heating coils and radiators
  • Offset configuration with 3 3/16 in port spacing fits tight piping
  • Integrated air vent simplifies installation on unit heaters and sterilizers

Steam trap for convectors and radiators

This brass-bodied steam trap handles condensate loads up to 162 lb/hr in applications such as convectors, steam kettles, evaporators, heating coils, radiators, sterilizers, steam tracing and unit heaters. It is rated for a maximum operating pressure of 25 psi and a temperature limit of 353F. The unit includes an integrated air vent and features an offset configuration.

Sustained condensate discharge at rated pressure

Under continuous operation the trap modulates to discharge condensate at the rated 162 lb/hr capacity while maintaining the 25 psi pressure ceiling. The brass body and internal mechanism are designed to withstand the 353F upper temperature without degradation, and the included air vent continuously removes non-condensable gases to preserve heat-transfer efficiency during long duty cycles.

Offset NPT connections simplify pipe alignment

The trap provides a female 3/4 in NPT inlet and a matching outlet spaced 3 3/16 in apart on an offset centreline, allowing direct replacement of existing 17C series units without re-piping. The integral air vent eliminates the need for a separate vent fitting. Installers should verify that the system pressure never exceeds 25 psi and that the piping can accommodate the fixed 3 3/16 in port spacing, otherwise the trap will not seal correctly.

Questions about this item

How much heat does the 17C-S-3-25 steam trap handle during continuous operation?

The trap is rated for 353 °F maximum temperature and a condensate capacity of 162 lb/hr, so it dissipates the heat of that steam load without external cooling.

What piping must already be in place for the 3/4 in NPT female inlet to connect?

You need a 3/4 in male NPT pipe thread on the supply line; the offset body sits 3 3/16 in between ports, so the existing piping must match that spacing.

Will the 25 psi maximum pressure rating work with a legacy low-pressure boiler running below 16 psi?

Yes, the trap operates up to 25 psi, so a system running at 16 psi or lower is well within its design range.
