ABS Coupling - Products
An ABS coupling joins two lengths of ABS pipe in a straight run, extending a drain, waste or vent line or repairing a cut section. Moonshine Bath stocks solvent-weld ABS couplings in common DWV sizes for residential and commercial plumbing.
Couplings are the simplest, most-used fitting for lengthening a run. Each coupling ships free across the USA, Canada and Mexico, leaves the warehouse within 24 hours on weekday orders before 2 PM EST, and is backed by our price match plus 10 percent beat guarantee.
Frequently Asked Questions
What is the difference between a coupling and a repair coupling?
A standard coupling has an internal stop that centers the pipes. A repair or slip coupling has no stop, so it can slide fully onto one pipe and then back to bridge a cut in an existing line.
How do I join two different pipe sizes?
Use a reducing coupling or a bushing to step between sizes. A straight coupling joins same-size pipe. Check the listing for reducing options if your sizes differ.
