Fernco fernco-qc103 Pipe End Cap 3 Inch Pvc

Product Description

The FERNCO fernco-qc103 is a 3-inch flexible PVC pipe end cap designed for fast, reliable sealing of open pipe ends, test lines, and clean-out access points. Built from flexible PVC, this cap delivers lasting performance in both above-ground and below-ground installations. Plumbers and pipe technicians use it to isolate sections of pipe during pressure testing or to permanently or temporarily cap unused lines. Installation requires no special tools — place the cap over the open pipe end and tighten to the specified torque. The flexible construction accommodates minor pipe irregularities and provides a secure, leak-resistant seal.

The fernco-qc103 is suited for residential and light commercial plumbing applications where a quick, dependable pipe cap is needed. It works on standard pipe ends in drain, waste, and vent systems. The cap is equally at home on exposed above-ground clean-outs and buried underground piping. When installing on corrugated pipe, hand-tighten only — do not apply full mechanical torque, as the corrugated profile requires a gentler seating approach to maintain a proper seal.

Key Features

• Flexible PVC construction handles above-ground and underground service conditions
• Fits 3-inch pipe ends for drain, waste, and vent applications
• Simple installation — place over pipe end and tighten to 60 inch-pounds of torque
• Hand-tighten only when used on corrugated pipe to avoid seal damage
• Suitable for pipe pressure testing and clean-out capping

Compatibility

Designed as an OEM-style replacement and general-use cap for 3-inch pipe ends in residential and commercial drain, waste, and vent plumbing systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Shut off water supply and depressurize the line before capping any active pipe. Place the cap squarely over the open pipe end and tighten to 60 inch-pounds of torque using a torque wrench or screwdriver — do not overtighten. On corrugated pipe, hand-tighten only to avoid distorting the sealing surface.
