상품 특징

• Exact Size and Thread Specifications: this pack contains 40 iron reducing coupling with precise external dimensions of approximately 1.5 inch in width and 1.4 inch in height; Both ends feature 1/2 inch × 3/4 inch internal threads (FNPT), compatible with matching external-thread pipes to achieve accurate diameter reduction connections in repeatable assemblies
• Malleable Cast Iron Build with Protective Black Finish: each 3/4 x 1/2 reducing coupling is constructed from black malleable cast iron and is finished with a high-temperature black oil film that imparts an industrial texture and improved corrosion resistance; The combination of material and surface treatment helps maintain shape under routine mechanical stress and supports long-term applied performance
• Professional Internal Threading for Secure Transitions: the internal FNPT threading on both ends is machined to ensure a tight, low-clearance joint when screwing 3/4-inch external-thread pipe down to a 1/2-inch external-thread pipe, making these black reducing coupling suitable for low-pressure conveyance of air, gas, and non-potable water in HVAC, light industrial, and DIY plumbing adaptations
• Design for Industrial and Retro Decor Projects: with a black, industrial aesthetic and compact profile, these iron reducing couplings integrate seamlessly into retro, country, or industrial-style interiors; They can be applied as hardware elements or visual accents when creating shelves, tables, lamps, or exposed-pipe furniture, contributing both form and functional connection points
• Simple Screw-on Installation and Bulk Supply: no complex tooling is required for typical installation—these screw-in couplings engage directly with external threaded pipe for quick assembly—and a pack of 40 is provided to meet the demands of bulk builds; This makes them suitable for furniture fabricators, DIY makers, and large-scale decorative installations where many fittings are needed
