## Long description

Opal coupling reducer N4 threaded 2.5 x 1" zinc-plated (model 241-41V) is a threaded pipe reducer designed to connect or adapt piping, fittings and threaded conduits of two different diameters. The zinc-plated finish provides enhanced surface corrosion resistance and a uniform appearance, while the N4 threaded configuration ensures a secure mechanical connection for fluid or air systems. The component is intended for use where a reliable threaded transition is required in plumbing, HVAC and general pipework.
Advantages
The zinc-plated surface reduces oxidation and extends service life in standard indoor and protected outdoor environments. Threaded connections allow quick assembly and disassembly without special tools beyond common wrenches or spanners. Compact dimensions make the reducer suitable for confined spaces and retrofitting jobs where matching different thread sizes is necessary. The product is compatible with standard threaded piping practices and provides a stable, leak-resistant joint when properly installed with appropriate thread sealant.
Suitable for
 Plumbing repairs and installations where different threaded pipe diameters must be joined
 HVAC ductwork and condensate drain lines requiring threaded adaptors
 General industrial or workshop pipework and fluid transfer systems
 Retrofit projects in confined spaces where compact threaded fittings are needed
Key specifications
 Type: Threaded coupling reducer
 Thread sizes: 2.5" to 1" transition (threaded connection on both ends)
 Material finish: Zinc-plated for corrosion resistance
 Thread form: Standard N4 threaded configuration
 Application: Suitable for liquid and air systems in plumbing, HVAC and general pipework
How to use
Ensure mating threads on pipes or fittings are clean and undamaged before assembly. Apply an appropriate thread sealant or PTFE tape to the male thread according to the fluid system requirements and manufacturer recommendations. Hand-start the coupling reducer onto the male thread, then tighten with a wrench or spanner until a snug, leak-free joint is achieved; avoid over-tightening to prevent thread damage. For disassembly, reverse the process and inspect threads and sealing surfaces for wear before reusing.
Usage recommendations
Use the zinc-plated coupling reducer in environments where moderate corrosion resistance is sufficient; for highly corrosive or marine environments, consider fittings with specialized coatings or stainless materials. Verify thread compatibility and pressure ratings for your system, and replace thread sealant if the joint is serviced.
