Description
PVC SDR 35 Pipe Increaser-Reducer (Hub x Hub)
PVC SDR 35 Pipe Increaser-Reducers provide a smooth transition between different SDR 35 pipe diameters in gravity-flow, non-pressure sewer and drainage systems.
Featuring hub connections on both ends, this increaser-reducer is designed to connect two different SDR 35 PVC pipe sizes within the same drainage system. The molded transition helps maintain proper alignment and efficient flow while reducing the need for multiple fittings. Constructed from durable PVC, the fitting provides lightweight handling along with resistance to corrosion, moisture, and many compatible chemicals for dependable use in residential, commercial, and municipal underground sewer and drainage applications.

Connection Configuration
Larger Hub Connection
The larger hub accepts the corresponding larger SDR 35 PVC pipe size for solvent-weld installation.
Smaller Hub Connection
The smaller hub accepts the corresponding smaller SDR 35 PVC pipe size, creating the size transition within the fitting.
Increaser-Reducer Design
The fitting combines two different hub diameters in a single molded transition to connect different SDR 35 pipe sizes.
Depending on system orientation, the same fitting may function as either an increaser or a reducer. The key requirement is matching each hub to the correct SDR 35 pipe size.
The gradual transition helps maintain continuity through the piping system while avoiding the additional joints that may be required when multiple separate fittings are used.

Construction Details
Manufactured from rigid PVC, this increaser-reducer is designed for long-term underground sewer and drainage service.
The material provides resistance to corrosion, moisture, and many compatible chemicals while remaining lightweight for easier handling during installation.
Precision-molded hub connections help provide proper fit and alignment with the corresponding SDR 35 PVC pipe sizes.
Installation
Verify both nominal hub sizes before installation and confirm which side connects to the larger SDR 35 pipe and which side connects to the smaller pipe.
Cut both mating PVC pipe ends square and remove burrs or debris that could interfere with proper insertion.
Clean and prepare the pipe ends and fitting hubs according to accepted PVC solvent-weld installation procedures.
Dry-fit both pipe sections into the fitting before applying primer or solvent cement to confirm size compatibility, insertion depth, orientation, and alignment.
Apply approved PVC primer and solvent cement as required for the piping system and fully seat each pipe into its corresponding 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 and smaller pipe sizes, SDR 35 compatibility, flow layout, and sewer or drainage application before you order.

What is a PVC SDR 35 pipe increaser-reducer used for?
It is used to connect two different SDR 35 PVC pipe diameters within a gravity-flow sewer or drainage system.
Why is it called an increaser-reducer?
The fitting can function as either an increaser or a reducer depending on the direction of the piping layout and which size is upstream or downstream.
What does Hub x Hub mean?
It means both ends are socket-style hub connections designed to receive compatible SDR 35 PVC pipe.
Are both hubs the same size?
No. An increaser-reducer is specifically designed with different hub sizes so it can transition between two pipe diameters.
How is the fitting installed?
Both hub connections are intended for solvent-weld installation using compatible PVC preparation materials, primer, and solvent cement as required.
Is this fitting designed for pressure piping?
No. The supplied product information identifies it for non-pressure gravity-flow sewer and drainage applications.
Can it be used underground?
Yes. The supplied product information identifies underground sewer and drainage systems as typical applications.
Can it be used in sanitary sewer systems?
Yes. Sanitary sewer service is identified as an intended application.
Can it be used for stormwater drainage?
Yes. The supplied product information identifies stormwater systems as a suitable application.
Does the fitting help reduce the number of joints?
It can. Because the pipe-size transition is incorporated into one fitting, fewer separate transition components may be needed.
Does pipe orientation matter?
Yes. Confirm which hub connects to each pipe size and make sure the fitting orientation is appropriate for the intended drainage layout.
What should I verify before ordering?
Confirm both SDR 35 pipe sizes, the required increase or reduction, system orientation, application type, and compatibility with the intended sewer or drainage system.
