Watts 0036046 Thermostatic Steam Trap 25 Psi 3/4 Inch

Product Description

The WATTS 0036046 is a two-port, angle-body thermostatic steam trap designed for low-pressure and vacuum steam heating systems. Built from cast iron, it handles a maximum working pressure of 25 psi and a maximum temperature of 406 degrees F. The trap connects via threaded 3/4-inch pipe fittings and provides a condensate capacity of 858.7 pounds per hour. Thermostatic traps discharge condensate below steam temperature, preventing live steam loss while venting air and non-condensable gases automatically. Licensed plumbers and pipefitters install this trap as part of hydronic and steam heating service work.

This trap is rated for use in low-pressure and vacuum steam heating applications. Typical installation points include radiators, convectors, fin pipes, drip points, unit ventilators, and air vents. The angle-body configuration suits inline installations where a 90-degree flow path is required. At 3.13 inches in overall length and weighing 12.6 pounds, it is sized for residential and light commercial steam systems. The threaded connection style simplifies replacement on existing threaded pipe runs without additional fittings.

Compatibility

Designed for use in low-pressure and vacuum steam heating systems including radiators, convectors, fin pipes, drip points, unit ventilators, and air vent applications requiring a 3/4-inch threaded angle-body thermostatic trap rated to 25 psi.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Shut off steam supply and allow the system to depressurize and cool completely before removing the existing trap or fitting new connections. Apply appropriate thread sealant rated for steam service to all threaded joints. Consult local plumbing codes and ASME guidelines for steam trap installation requirements on low-pressure systems.
