90 Degree Elbow, Slip x Slip PVC Schedule 40 5" (406-050)

The 406-050 is a 5" Schedule 40 PVC 90° Elbow with Slip x Slip connections. This fitting redirects flow at a true right angle on large-diameter PVC pressure pipe systems, accepting solvent cement on both ends for a permanent, pressure-rated bond to standard Schedule 40 PVC pipe. At 5", this is a large-format commercial and industrial fitting — the size alone places it firmly in the territory of municipal infrastructure, high-volume irrigation systems, industrial process piping, and large commercial plumbing applications where significant flow capacity is required.

Both slip sockets are sized to accept standard 5" Schedule 40 PVC pipe, and the 90° sweep geometry directs flow cleanly through the turn. Proper solvent cementing practice at this diameter is important — large-diameter joints require a two-step primer and cement application with adequate assembly time before the joint sets, and the fitting should be held firmly in alignment for the full recommended cure period before the system is pressurized.

The white Schedule 40 PVC compound provides solid corrosion resistance across a broad range of fluids, good impact resistance under normal service conditions, and a significantly lower installed weight compared to ductile iron or steel elbows of equivalent size — a meaningful labor and handling advantage at 5". While Schedule 40 carries a lower pressure rating than Schedule 80 at equivalent sizes, it remains well-suited for the majority of large-diameter commercial and municipal applications where system pressures fall within its rated range and the weight and cost advantages of Schedule 40 are the determining specification factors.

Specifications:

⚠️ Note: Pressure ratings decrease as operating temperature increases. At large diameters, proper two-step solvent weld procedure (primer + cement) is critical — do not skip priming on 5" joints. Allow full cure time before pressurizing per the cement manufacturer's instructions.

Industries & Applications:

• Municipal Water Distribution — Used in large-diameter PVC distribution mains, service laterals, and transmission line direction changes where Schedule 40 is the specified material and system pressures are within rated range
• Irrigation & Agricultural Systems — Routes high-volume mainlines around structures, grade changes, and field boundaries on large-scale agricultural and commercial irrigation systems
• Industrial Process Piping — Directs large-diameter process water, cooling water, or non-aggressive chemical lines through 90° turns on industrial facilities and manufacturing plants
• Water & Wastewater Treatment — Used in plant influent and effluent piping, filter backwash lines, and large-diameter distribution headers within treatment facility boundaries
• Commercial & Institutional Plumbing — Specified on large commercial building domestic water mains, fire suppression system supply lines, and campus utility distribution where PVC is the approved material
• Aquaculture & Commercial Pool/Spa — Used in high-flow recirculating system headers and large-diameter return lines where corrosion-resistant, lightweight piping is specified
