45 Degree Elbow, FPT x FPT PVC Schedule 80 4" (819-040)

The 4" PVC Schedule 80 45-Degree Elbow (FPT x FPT) provides a reliable, threaded change in direction for high-pressure industrial and commercial piping systems. With female NPT threads on both ends, this fitting accepts standard threaded pipe or nipples for tool-free disassembly and easy field modification — a practical advantage in maintenance-heavy environments where solvent-welded fittings would require cutting out.

Schedule 80 PVC offers significantly greater wall thickness and pressure ratings than standard Schedule 40 fittings, making it the preferred choice in applications where elevated pressures, mechanical stress, or corrosive chemical exposure demand a more robust solution. The 45° bend geometry allows for gradual directional changes that reduce flow turbulence compared to a 90° elbow, improving overall system efficiency in longer runs.

This fitting is manufactured to ASTM D2467 standards and is suitable for use with Schedule 80 PVC pipe systems in both above-ground and below-grade installations where threading is specified.

Specifications:

Industries & Applications:

• Industrial Process Piping — Ideal for chemical transfer lines where corrosion resistance and higher pressure ratings are required
• Water & Wastewater Treatment — Used in pump stations, filtration systems, and treatment plant piping where threaded connections enable routine maintenance access
• Commercial Plumbing & Mechanical — Suited for commercial buildings requiring heavy-duty fittings in mechanical rooms or utility spaces
• Irrigation & Agricultural Systems — Appropriate for mainline directional changes in high-demand irrigation infrastructure
• Chemical Processing — Resistant to a wide range of acids, bases, and industrial chemicals commonly handled in Sch. 80 PVC systems
• Municipal & Government Facilities — Specified in public works and infrastructure projects that require ASTM-compliant Schedule 80 fittings
