The Dearborn 791b-17bn-1 is a 1-1/4 inch diameter by 24 inch slip joint extension tube designed for tubular drain installations in residential and commercial plumbing applications. Built from brass with a chrome plated finish, this extension tube delivers the durability and corrosion resistance that plumbers and drain installers depend on for long-lasting performance under sinks and in drain assemblies. The 17 gauge material thickness provides a solid, reliable wall strength that holds up to regular use without distorting or collapsing under pressure. The chrome plated exterior gives the tube a clean, professional look that complements standard drain hardware and P-traps. This tube is used to extend or complete the drain line between a sink basket strainer and the P-trap or wall drain connection. It fits standard 1-1/4 inch slip joint fittings, making it compatible with a wide range of tubular drain configurations. Each tube includes one brass nut and one rubber washer, which together form a tight, leak-resistant slip joint connection without the need for additional hardware or thread sealant. The slip joint design allows for quick adjustment during installation, saving time on the job. The 791b-17bn-1 meets the cUPC applicable standard, confirming compliance with recognized plumbing product requirements. At 24 inches in length, this tube provides enough reach to handle deeper cabinet installations or extended drain runs where a shorter tube would fall short. Plumbers, remodelers, and maintenance professionals working on kitchen or bathroom sink drains will find this tube straightforward to cut to length and install. It is sold 10 per carton, making it a practical stock item for supply houses and contractors who handle multiple drain installations regularly.
The Dearborn 791b-17bn-1 slip joint extension tube provides a reliable, code-compliant solution for completing tubular drain installations, combining 17 gauge brass construction with included slip joint hardware for efficient, leak-resistant connections.
