PVC Drainage Pipe Reducer Bushing Connector Adapter Joints Drain Fittings

Measure the outer diameter (OD) of the smaller pipe and the inner diameter (ID) of the larger fitting socket you are connecting to. The first number in the model name (e.g., 110 in 110×75mm) refers to the larger socket end; the second number refers to the smaller spigot end. Match these to your existing pipe dimensions to select the correct model.

Yes. Rigid PVC DWV fittings are the industry standard for residential and light-commercial drain stack connections. The bushing-style design, when properly solvent-welded, creates a joint that is typically stronger than the pipe itself under normal gravity-drain conditions.

PVC is inherently resistant to most household drain chemicals, including common drain cleaners, soaps, and organic waste. It does not rust or corrode. For applications involving highly concentrated industrial solvents, verify chemical compatibility before installation.

This is a PVC fitting and is designed for use with PVC pipe and PVC solvent cement. Connecting PVC to ABS requires a transition cement and may be subject to local code restrictions. Check your local plumbing code before mixing pipe materials.

Rigid PVC DWV fittings are commonly used in underground and in-slab drain applications when properly bedded and backfilled per local code. Confirm that the specific fitting meets the schedule or standard required by your local jurisdiction (e.g., Schedule 40 DWV) before burying.

No special tools are required. Standard installation uses PVC primer, PVC solvent cement, a dauber or brush, and a clean rag. Apply primer to both mating surfaces, apply cement, insert the bushing with a quarter-turn, and hold for 30 seconds. Allow full cure time per the cement manufacturer's instructions before running water.

A reducer bushing inserts into an existing socket fitting, converting it to accept a smaller pipe — it adds minimal length to the assembly. A reducer coupling is a standalone fitting with two sockets of different sizes. Bushings are preferred when space is limited or when you want to avoid adding an extra fitting to the run.
