Description
PVC SDR 35 Reducing Bushing (SPG x Hub)
PVC SDR 35 Reducing Bushings provide a compact transition between different SDR 35 pipe sizes in non-pressure sewer and drainage systems.
Featuring a spigot (SPG) connection on one end and a hub connection on the other, this reducing bushing is designed to connect a smaller SDR 35 pipe size into a larger piping system. The spigot end fits into a compatible larger hub, while the smaller hub end accepts the corresponding smaller SDR 35 PVC pipe. Constructed from durable PVC, the fitting offers lightweight handling along with resistance to corrosion, moisture, and many compatible chemicals for dependable underground sewer, stormwater, wastewater, and drainage service.

Connection Configuration
Spigot Connection
The spigot end is designed to fit into a compatible larger SDR 35 hub or fitting for solvent-weld installation.
Reducing Hub Connection
The smaller hub accepts compatible SDR 35 PVC pipe, completing the reduction to the smaller nominal pipe size.
Reducing Bushing Design
The reducing bushing combines a larger spigot-style connection and a smaller hub connection into one compact fitting.
The spigot end inserts directly into an existing compatible hub, while the smaller hub accepts the reduced SDR 35 pipe size.
This configuration can provide a compact fitting-to-fitting transition and may reduce the need for a separate coupling and reducer in some installations.
Why Choose a PVC SDR 35 Reducing Bushing?
Compact Size Transition

- Smaller hub accepts reduced pipe size
- Can reduce overall fitting count
- Useful where installation space is limited
PVC Construction
- Corrosion resistant
- Lightweight construction
- Suitable for underground service
- Resistant to moisture exposure
- Suitable for many compatible drainage environments
Typical Applications
Sewer Systems
- Sanitary sewer piping
- Building sewer connections
- Residential sewer lines
- Commercial sewer systems
- Municipal sewer installations
Drainage Systems
- Stormwater drainage
- Wastewater piping
- Underground drainage
- Gravity-flow drain systems
- Pipe-size reductions
Construction Details
Manufactured from durable PVC, this reducing bushing is designed for long-term service in underground sewer and drainage environments.
The PVC material provides resistance to corrosion, moisture, soil conditions, and many compatible chemicals while remaining lightweight for easier handling and installation.
Precision-molded spigot and hub connections help provide proper fit and alignment with compatible SDR 35 pipe and fittings.
Installation
Verify both nominal connection sizes before installation and confirm which side is the larger spigot and which side is the smaller hub.
Confirm that the spigot end matches the intended larger SDR 35 hub and that the smaller hub matches the intended reduced pipe size.
Cut the mating smaller SDR 35 pipe square and remove burrs or debris that could interfere with proper insertion.
Clean and prepare the spigot, mating larger hub, smaller pipe, and reducing hub according to accepted PVC solvent-weld installation procedures.
Dry-fit both sides before applying primer or solvent cement to confirm size compatibility, insertion depth, orientation, and alignment.
Apply approved PVC primer and solvent cement as required and fully seat the spigot into the larger mating hub and the smaller pipe into the reducing hub.
Maintain proper alignment while the joints set and allow the solvent-weld connections to cure according to the solvent cement manufacturer's recommendations before placing the drainage system into service.
Our piping specialists can help review your larger hub size, reduced pipe size, spigot connection, and SDR 35 sewer or drainage application before you order.

What is a PVC SDR 35 reducing bushing used for?
It is used to transition from a larger SDR 35 fitting or hub connection to a smaller SDR 35 pipe size.
What does SPG x Hub mean?
It means one end is a spigot connection that inserts into a compatible hub, while the opposite end is a hub that receives compatible SDR 35 pipe.
What does SPG mean?
SPG means spigot. The spigot end fits inside a compatible hub rather than receiving pipe itself.
Which end is the larger connection?
The supplied product description identifies the spigot end as fitting into the larger hub, while the hub end accepts the smaller pipe size.
How is this different from a Hub x Hub increaser-reducer?
A Hub x Hub increaser-reducer receives pipe at both ends. This reducing bushing uses a spigot on the larger side so it can insert directly into an existing hub.
Can the spigot fit directly into another SDR 35 fitting?
Yes. The spigot is designed to fit into a compatible SDR 35 hub or fitting of the correct size.
How is the smaller pipe connected?
The smaller SDR 35 pipe inserts into the reducing hub and is joined using an appropriate PVC solvent-weld connection.
Does this fitting require solvent cement?
Yes. Both the spigot-to-hub and pipe-to-hub connections are intended for compatible PVC solvent-weld installation.
Is this fitting intended for pressure systems?
No. The supplied product information identifies it for non-pressure sewer, stormwater, wastewater, and drainage systems.
Can it be used underground?
Yes. The supplied product information identifies underground sewer and drainage applications as intended uses.
Can it be used in sanitary sewer and stormwater systems?
Yes. Both sanitary sewer and stormwater systems are identified as suitable applications.
What should I verify before ordering?
Confirm the larger mating hub size, spigot size, reduced hub size, smaller SDR 35 pipe size, and compatibility with the intended sewer or drainage system.
