Armstrong International 880-1/2-125 1/2″ NPT 125 PSI Cast Iron Inverted Bucket Steam Trap

Description

The Armstrong International Series 880 Cast Iron Inverted Bucket Steam Trap (Model 880-1/2-125) is a dependable, time-tested solution for steam condensate removal in commercial and industrial HVAC and process piping systems. Built with a rugged cast iron body, this trap is engineered to withstand demanding steam system environments while delivering consistent, energy-efficient performance.

The inverted bucket design is one of the most reliable steam trap mechanisms available — it mechanically responds to the difference in density between steam and condensate, opening to discharge condensate and air while snapping shut to prevent live steam loss. This results in reduced energy waste and lower operating costs over the life of the system.
