Reducing Coupler for Vibration-Prone Systems

The Banjo 303B200A is a 3-inch female coupler joined to a 2-inch male adapter, built for drain and trap assemblies. Its all-stainless construction resists corrosion while the poly cam lever provides quick, tool-free engagement. The design targets installations where movement or vibration would loosen standard threaded joints.

Stainless Build with Lever Locking

Three-arm lever action distributes clamping force evenly around the seal, reducing the chance of leaks when pipes shift. Stainless steel hardware withstands harsh chemical environments and repeated connect-disconnect cycles without galling. Black finish aids visual identification in crowded pipe runs.

Replaces Threaded Reducers in Mobile Service

This coupling replaces threaded reducer bushings that back off under road vibration or pump pulsation. The jump is worth it when maintenance intervals demand fast disassembly or when thermal cycling cracks pipe dope on conventional threads. Not suited for gravity-only drains that never require separation.

Questions about this item

What thread standard does the 3" female coupler use?

The coupler uses a standard cam-lever interface that locks by hand pressure; no threads are engaged.

What pipe diameters must the installation accommodate?

The fitting connects a 3-inch female cam opening to a 2-inch male cam adapter.

How is the coupling secured and what step is often missed?

Close both cam arms until they snap over-center; the step often missed is verifying both arms are fully latched before pressurising.
