4-inch PVC hub elbow for drainage systems

This 45-degree hub trap connects four-inch PVC pipe in non-pressure drainage installations. The Schedule 40 fitting meets ASTM D1784 cell class 12454 for material quality. It is intended for plumbers and contractors assembling DWV systems.

Behaviour under sustained flow conditions

The fitting handles continuous gravity drainage at temperatures up to 140 degrees F without pressure rating. PVC construction resists corrosion from typical waste water chemistry. Joint integrity depends on proper solvent cement technique rather than mechanical seals.

Thermal limits and installation noise profile

Maximum service temperature is 140 degrees F, above which material softening may occur. The hub connection produces no operational noise once cemented and supported. No electrical power is required for this passive component.

Questions about this item

Does the PVC material soften if drain water runs hotter than 140 Degrees F all day?

The fitting is rated to a maximum temperature of 140 Degrees F; sustained exposure above that limit can soften the Schedule 40 PVC and compromise the joint.

What pipe and solvent cement must I already have to install this 4 in hub elbow?

You need 4 in Schedule 40 PVC pipe and PVC solvent cement that meets ASTM D1784 cell class 12454 for a code-compliant hub connection.

Will this 45-degree hub trap connect directly to older ABS drain lines in the same 4 in size?

No — the hub is designed for PVC pipe only; joining it to ABS requires a listed transition coupling, not a direct solvent-weld.
