Description
PVC DWV Flush Bushing (SPG x HUB)
PVC DWV Flush Bushings provide a compact way to reduce pipe size within non-pressurized drain, waste, and vent piping systems.
Featuring a spigot (SPG) connection on the outside and a smaller hub connection on the inside, this fitting installs into a compatible larger hub while accepting a smaller PVC DWV pipe. The flush design minimizes projection from the surrounding fitting and provides a clean, space-efficient transition between pipe sizes.

Connection Configuration
Outer Spigot
The SPG exterior is designed to fit directly into a compatible larger PVC hub fitting.
Flush Reducing Body
The compact body reduces the connection size while minimizing the amount of fitting projection from the larger hub.
Inner Hub
The smaller hub accepts compatible PVC DWV pipe for a permanent solvent-weld connection.
Construction Details
PVC DWV flush bushings are manufactured from durable PVC for corrosion resistance and dependable long-term service in compatible non-pressure drainage systems.
The exterior spigot surface fits into a larger compatible hub while the internal hub receives a smaller pipe, creating a compact size transition within the fitting.
Smooth internal surfaces help reduce unnecessary flow restriction and support efficient drainage through the reduced connection.
Why Choose a Flush Bushing?
Compact Size Reduction
- Reduces between different nominal pipe sizes
- Fits directly into an existing hub
- Minimizes fitting projection
- Useful in confined piping layouts
- Eliminates the need for a longer reducing fitting
PVC DWV Construction
- Corrosion-resistant material
- Lightweight construction
- Suitable for solvent-weld assembly
- Designed for non-pressure drainage systems
- Suitable for long-term DWV service
Typical Applications
Drain & Waste Systems
- Residential drainage piping
- Commercial waste piping
- Fixture drain systems
- Building drainage systems
- General DWV installations
Pipe Size Transitions
- Reducing hub connections
- Branch drainage systems
- Vertical and horizontal DWV piping
- Repair and retrofit work
- Space-sensitive piping layouts
Solvent-Weld Installation
Clean and prepare the compatible larger hub and bushing spigot according to accepted PVC solvent-weld procedures. Apply compatible primer and solvent cement where required and fully seat the bushing into the hub.
Prepare the smaller PVC DWV pipe in the same manner and fully insert it into the bushing's hub connection. Allow both solvent-weld joints to cure according to the cement manufacturer's recommendations before placing the system into service.
Our plumbing specialists can help review your larger hub size, smaller pipe size, DWV application, and solvent-weld requirements before you order.

What is a PVC DWV flush bushing?
A flush bushing is a compact reducing fitting that installs into a larger hub and accepts a smaller pipe.
What does SPG mean?
SPG means spigot. The exterior spigot surface is designed to fit into a compatible hub fitting.
What does HUB mean?
Hub refers to the socket connection that accepts compatible PVC pipe for solvent-weld installation.
Why is it called a flush bushing?
The compact design reduces pipe size while minimizing how far the fitting projects from the surrounding hub connection.
How does this fitting reduce pipe size?
The outer spigot fits into the larger hub while the smaller internal hub accepts the reduced-size PVC pipe.
How is the fitting installed?
Both the spigot-to-hub and smaller pipe-to-hub connections are installed using compatible PVC solvent-weld procedures.
Is this fitting intended for pressure piping?
No. The supplied product information identifies this bushing for non-pressure drain, waste, and vent systems.
What material is the fitting made from?
The flush bushing is manufactured from durable, corrosion-resistant PVC.
Can this bushing connect two pipes of the same size?
No. A flush bushing is a reducing fitting intended to transition from a larger connection to a smaller pipe size.
What should I verify before ordering?
Confirm both the larger spigot size and smaller hub size, as well as compatibility with the existing PVC DWV fittings and pipe.
