4 inch PVC Sewer and Drain 90 Degree Long Turn Elbow Hub x Hub

P256 WEST S&D 90° Long Turn Elbow HXH 4 inch – Optimized for Smoother Drainage Transitions

The P256 WEST 4 inch Solvent Weld Sewer & Drain (S&D) 90° Long Turn Elbow is specifically engineered for gravity-flow applications where smoother directional changes are essential. Designed with a long-radius sweep, this fitting minimizes flow resistance and reduces turbulence in horizontal to vertical transitions—making it an ideal choice for drainage and waste systems.

Key Performance Features

• Long Turn Radius – The extended arc significantly reduces friction loss, supporting efficient flow and minimizing debris accumulation.
• Schedule 40 Compliant – Compatible with SDR-35 and ASTM D3034 S&D piping systems, ensuring dimensional compatibility with standard solvent weld drainage components.
• Heavy-Duty PVC Construction – Molded from impact-resistant polyvinyl chloride for long-term durability in underground or exposed environments.
• Hub x Hub Connection – Allows easy integration into solvent weld sewer systems, promoting strong, leak-resistant joints.
• Meets Industry Codes – Fabricated in compliance with ASTM D3034 and D1784 standards for gravity-flow fittings.

Technical Specifications

• Model: P256 WEST 7026
• Size: 4 inch
• Material: PVC (polyvinyl chloride)
• Connection: Hub x Hub
• Application: Non-pressure Sewer & Drain Systems
• Standards: ASTM D3034, D1784

Installation Guidance

Installation involves standard solvent welding procedures. Proper pipe preparation—including cleaning, priming, and solvent application—is required for secure bonds. Ensure joints are fully seated and allow adequate curing time before backfilling or pressurizing adjacent systems.

Common Applications

• Horizontal and vertical transitions in storm and sanitary sewer systems
• Foundation drainage and landscape runoff infrastructure
• Non-potable wastewater and gray water routing in residential and commercial projects

Code Consideration

Long-turn elbows are often required by plumbing code in certain configurations due to their superior hydraulic efficiency compared to short-radius options. They are particularly beneficial in clean-out configurations or extended runs.

With its long sweep design and durable build, the P256 WEST S&D 90° Long Turn Elbow is the professional’s choice for efficient flow and code-compliant installations. Suitable for both new system layouts and retrofit applications, this fitting enhances the reliability and performance of any drainage project.
