Mepco (Dunham Bush) D4661 Trap
The Mepco (Dunham Bush) D4661 is a high-performance 1/2" 1E-SW straight way trap engineered for reliable condensate management in low-pressure and sub-atmospheric steam heating systems. Designed for horizontal installation, this thermostatic radiator trap features a rugged brass construction with a union inlet to simplify field mounting on radiators, convectors, and unit heaters. It operates effectively across a broad pressure range from 25" Hg vacuum to 25 psi, ensuring sensitive response to temperature changes while preventing live steam from escaping into the condensate return lines. The straight-way configuration provides a streamlined flow path with minimal pressure drop, which is critical for maintaining thermal efficiency in commercial and industrial HVACR setups. As a direct OEM replacement steam trap for legacy Dunham Bush 1E series models, the D4661 is the industry standard for contractors looking to reduce water hammer and optimize steam system performance without restructuring existing piping.
Key Benefits:- Optimized Condensate Drainage: Designed specifically for horizontal piping to ensure dry steam and efficient heat transfer.
- Broad Pressure Compatibility: Maintains consistent operation in both high-vacuum and low-pressure systems up to 25 psi.
- Durable Brass Housing: Heavy-duty construction with a union inlet for secure, leak-proof connections in demanding environments.
- Precision Control: Sensitive thermostatic element prevents steam loss while effectively venting air and non-condensable gases.
Is the Mepco D4661 compatible with older Dunham Bush 1E traps?
Yes, the D4661 is the direct equivalent for the 1/2" 1E-SW straight-way pattern and fits the same physical footprint and capacity requirements of legacy installations.
Does this trap require specific tools for maintenance?
The D4661 features a standard union connection and can be serviced or replaced using common technician hand tools, facilitating rapid repairs on the job site.
Can this trap be used in vertical piping runs?
No, the 1E-SW is specifically a straight-way horizontal pattern trap. For vertical applications, a vertical-style trap should be utilized to ensure proper drainage of the thermostatic element.
