Mission Rubber 703017 Rubber Clamp-on Test Cap 3 in

Product Description

The MISSION RUBBER 703017 is a 3-inch rubber clamp-on test cap used to temporarily seal and pressure-test drain, waste, and vent (DWV) piping systems. The cap clamps directly onto the end of a pipe, creating a watertight seal that allows the system to hold pressure or static water head during inspection. It is designed for quick installation and removal without adhesives or special tools. Plumbers and pipefitters use this cap during rough-in inspections to satisfy code-required DWV pressure tests before the system is concealed in walls or floors.

This test cap is suited for residential and light commercial plumbing applications. It fits onto 3-inch pipe ends and is commonly used on ABS, PVC, cast iron, and similar DWV piping materials. The clamp-on design makes it a practical choice during new construction, remodel work, or any situation where a temporary, reusable pipe seal is needed to facilitate a plumbing inspection or system test.

Key Features

• 3-inch clamp-on design seats directly on pipe ends without adhesives
• Rubber construction provides a flexible, watertight seal for DWV pressure testing
• Reusable and removable after inspection is complete

Compatibility

Designed as a temporary test fitting for 3-inch DWV piping systems in residential and commercial plumbing applications.

Installation Notes

Installation is performed by licensed plumbers during the DWV rough-in testing phase. Shut off all water supply to the system before attaching or removing test caps. Tighten the clamp evenly to ensure a uniform seal around the pipe end. Follow local plumbing code requirements, including IPC or applicable state codes, for minimum test pressure and duration before covering piping.
