Description
ABS DWV Expansion Joint (HUB x SPG)
ABS DWV Expansion Joints are designed to accommodate controlled movement caused by thermal expansion and contraction in non-pressure drain, waste, vent, sewer, and general drainage systems.
Featuring a hub connection on one end and a spigot (SPG) connection on the other, this fitting helps reduce stress on ABS DWV piping by allowing limited axial movement within the system. The hub end accepts compatible ABS pipe, while the spigot end is designed to fit into a compatible ABS DWV hub fitting. Manufactured for ABS DWV service, it meets recognized standards including ASTM D2661, CSA B181.1, and NSF Standard 14.

Connection Configuration
Hub Connection
The hub end accepts compatible ABS DWV pipe for a permanent solvent-cement connection.
Spigot Connection
The spigot end is designed to fit into a compatible ABS DWV hub fitting, allowing the expansion joint to be incorporated directly into the piping layout.
Expansion Joint Design
ABS piping can expand and contract as temperatures change. In longer piping runs, this movement can place stress on fittings, supports, and connected components if it is not properly accommodated.
The expansion joint is designed to provide a controlled point of movement within the piping system, helping reduce mechanical stress caused by thermal changes.
Its Hub x Spigot configuration can be useful where direct fitting-to-fitting integration is preferred on one side of the joint.

Installation
Verify the nominal hub and spigot sizes before installation and confirm compatibility with the intended ABS DWV pipe and mating hub fitting.
Determine the proper expansion joint location based on piping length, support arrangement, temperature range, and manufacturer installation requirements.
Cut the mating ABS pipe square and remove burrs. Clean and prepare the pipe, hub, spigot, and mating fitting surfaces according to accepted ABS solvent-cement installation procedures.
Position the expansion joint according to the manufacturer's required setting so adequate movement remains available for both expansion and contraction.
Apply compatible ABS solvent cement as required, fully seat the pipe into the hub and the spigot into the mating hub fitting, and maintain proper alignment during assembly.
Allow completed solvent-cement joints to cure according to the solvent cement manufacturer's recommendations before placing the drainage system into service.
Our piping specialists can help review your pipe size, piping length, temperature conditions, connection layout, and ABS DWV compatibility before you order.

What is an ABS DWV expansion joint used for?
It is used to accommodate controlled movement caused by thermal expansion and contraction in non-pressure ABS drain, waste, and vent piping systems.
What does HUB x SPG mean?
HUB means one end accepts compatible ABS DWV pipe, while SPG means the opposite end is a spigot designed to fit into a compatible ABS hub fitting.
Why is thermal expansion important in ABS piping?
ABS piping can change length as temperature changes. In longer runs, that movement can create stress if the piping system does not have a suitable method of accommodation.
Where are expansion joints commonly used?
They may be used in longer piping runs, vertical stacks, or installations exposed to meaningful temperature changes where controlled movement is needed.
Does this fitting require solvent cement?
The hub and spigot connections are intended for compatible ABS solvent-cement installation.
Is this fitting intended for pressure systems?
No. This fitting is intended for non-pressure drain, waste, vent, sewer, and general drainage applications.
Can it be used for compressed air or gas?
No. The supplied product information specifically states that ABS DWV fittings are not intended for transporting compressed air or gas.
Can this fitting be used for pressure testing?
No. The supplied product information states that ABS DWV fittings should not be used for pressure testing.
What is the maximum operating temperature?
The supplied product information specifies applications where operating temperatures do not exceed 140°F.
What should I verify before ordering?
Confirm the nominal hub and spigot sizes, mating ABS components, piping layout, expected temperature range, available movement, and intended non-pressure ABS DWV application.
