2 x 1-1/2 inch PVC DWV Flush Bushing Fitting x Plastic

2 x 1-1/2 Inch PVC DWV Flush Bushing – Hub x Spigot

This 2 x 1-1/2 inch PVC DWV flush bushing is engineered for reducing hub connections in drain, waste, and vent (DWV) systems. It allows for a smooth transition between 2-inch and 1-1/2-inch nominal pipe sizes and is designed to be solvent-welded into place, offering a compact, low-profile fit in tight installation spaces.

Performance and Material Standards

• Material: Rigid polyvinyl chloride (PVC) conforming to ASTM D2665 specifications for DWV applications
• Size: 2 inch x 1-1/2 inch nominal reduction
• Ends: Spigot end fits into 2-inch PVC hub; 1-1/2 inch hub accepts standard DWV pipe
• Compliance: Meets requirements of NSF Standard 14 and is listed for use in non-pressurized sanitary drainage systems
• Temperature Range: Suitable for systems not exceeding 140°F (60°C)

Key Functional Benefits

• Compact Profile: Flush-style design is ideal for installations where space is limited
• Chemical Resistance: Inert PVC material resists most household and industrial chemicals
• Corrosion-Free: Will not rust or degrade in acidic waste environments
• Consistent Fit: Manufactured to uniform dimensions for reliable solvent-weld joints

Installation Recommendations

Installation requires proper pipe preparation: pipe ends and bushing socket must be clean, dry, and free of burrs. Use ASTM D2564-compliant solvent cement and primer to join components. Allow sufficient curing time before pressurizing the system. Not intended for use in pressurized water applications.

Typical Applications

This DWV flush bushing is commonly used in residential and light commercial drainage systems where pipe size reduction is necessary at fixture drains, branch lines, or stack connections. It is suitable for both new construction and system modifications or retrofits.

Industry Insight

Flush bushings provide an effective means of reducing fitting profiles without sacrificing flow characteristics. Their installation flexibility and compatibility with standard DWV components make them a staple in code-compliant plumbing layouts.

The 2 x 1-1/2 inch PVC DWV flush bushing delivers dependable performance for professionals who require compact, code-approved solutions for adapting pipe sizes in non-pressurized drain systems.
