6 in PVC End Cap for Drain Lines

The Fernco QC-106 is a PVC round end cap sized for 6 in nominal pipe with a 6 5/8 in inside diameter. It terminates drain, waste or vent lines in residential and light commercial plumbing systems. The 2 in overall length keeps the fitting compact inside tight chases. A stainless steel interlocked worm-gear clamp is included for a secure mechanical seal.

Push-on Installation with Included Clamp

The cap slides over the pipe end and the supplied clamp tightens with a standard screwdriver or nut driver. No solvent cement, primer or special tools are required. The interlocked worm-gear design maintains even pressure around the circumference. Over-tightening can distort the PVC body, so stop when the clamp is snug and the joint shows no visible gaps.

Verify Pipe OD and Pressure Rating First

Confirm the existing pipe outside diameter matches the 6 5/8 in inside diameter of the cap before ordering. The fitting is rated for 4.3 psi maximum operating pressure and a temperature range of -30 to 140 degrees F. It is not intended for pressurised supply lines or temperatures outside the stated range. Shield is not included or required for this model.

Questions about this item

How can I confirm the QC-106 cap is sealing correctly after installation?

Pressurise the line up to 4.3 psi and check for leaks; the stainless-steel interlocked worm-gear clamp should hold the cap firmly on the 6 5/8 in inside diameter.

What components come with the QC-106 and what must I supply?

The box includes the PVC cap and one stainless-steel clamp; no shield is included and pipe or solvent cement are not supplied.

Which version of the QC-106 should I choose for a 6 in nominal pipe?

The QC-106 is a single 6 in nominal size cap rated from -30 to 140 degrees F, so select it when those dimensions and temperature limits match your system.
