Pasco 4417 Test Cap, Plumbing Rough-In Pressure Test Fitting

Pasco 4417 Test Cap, Plumbing Rough-In Pressure Test Fitting

The Pasco 4417 Test Cap is a plumbing accessory used by contractors and plumbers to temporarily seal open pipe ends during rough-in work. Test caps are a standard part of the DWV (drain-waste-vent) and supply-line testing process, allowing a section of pipe to be closed off so the system can be pressurized with air or water and checked for leaks before walls, floors, or slabs are closed up. This test cap is available across a range of pipe sizes from 1-1/2" through 6", so plumbers can stock the size needed for the specific rough-in run being tested. As a Pasco product supplied for professional and commercial plumbing use, the 4417 is intended to be installed, tested, and removed as part of a normal rough-in inspection workflow, then taken out of the line once the system passes inspection and the final fixtures or fittings are connected.

Key Features

• Test Cap Function: Designed to temporarily cap an open pipe end so the connected plumbing run can be pressure- or water-tested prior to final close-in.
• Size Range: Offered in sizes from 1-1/2" through 6" to match the pipe diameter being tested on the job.
• Rough-In Use: Intended for use during the rough-in stage of a plumbing installation, ahead of drywall, flooring, or slab pour, so leaks can be identified and corrected while the pipe run is still accessible.
• Removable Fitting: Functions as a temporary fitting that is removed once testing is complete and the permanent fixture, trap, or connection is installed in its place.
• Commercial and Residential Applications: Suited to both residential and commercial plumbing projects where code-required pressure or leak testing is part of the inspection process.
• Single-Unit Packaging: Supplied as a minimum order quantity of 1 EA per size, making it easy to stock individual units for service trucks or job-box supply.
