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.

Technical Specifications

  • Prop 65 Warning: Yes — this product carries a California Proposition 65 warning label as required by California law.
  • Product Type: Home Improvement & Commercial Supplies — Plumbing Accessories.
  • Available Sizes: 1-1/2", 2", 3", 4", 6".
  • Minimum Order Quantity: 1 EA.

Typical Applications

  • Residential and Commercial Rough-In Plumbing

Pasco 4417 – Frequently Asked Questions

1) What pipe sizes does the Pasco 4417 test cap come in?
Five sizes cover the common DWV runs: 1-1/2 inch (part 4417), 2 inch (4418), 3 inch (4419), 4 inch (4422) and 6 inch (4841). Order by the nominal pipe diameter you are capping, since each size is its own part number.
2) Is a test cap meant to stay in the line permanently, or do I pull it after inspection?
It comes out. The 4417 test cap is a temporary fitting: you cap the open pipe end, pressurize the run with air or water, check for leaks, then remove the cap once the system passes and install the permanent fixture, trap, or connection in its place. Nothing about it is intended to stay in a finished system.
3) Can I use a Pasco test cap for DWV drain lines or only water supply?
Both. Test caps like the 4417 are standard in DWV (drain-waste-vent) and supply-line testing, closing off a section so it can be pressurized with air or water before walls, floors, or slab are closed up. The size range running from 1-1/2 up to 6 inches is aimed squarely at drain and vent piping as well as smaller supply runs.
4) Do I have to buy a case, or can I get a single test cap for the truck?
Single units. Minimum order is 1 EA per size, so you can stock one of each diameter on a service truck or in a job box instead of committing to a carton.
5) At what stage of the job do I install these caps?
During rough-in, before drywall, flooring, or the slab pour. The point is to find and fix a leak while the pipe run is still open and reachable, which is also when the code-required pressure or leak test for inspection is normally performed on both residential and commercial work.
6) Does the Pasco 4417 test cap carry a California Proposition 65 warning?
Yes. The 4417 test cap ships with a California Proposition 65 warning label as required by California law. Facility and institutional buyers who track Prop 65 items should log it accordingly.
