01SEWAGE PUMPS
Sealed tight for the pressure test
Tucked into the architecture of your home’s drainage, this cap sits where water meets infrastructure. Its black and silver profile is functional yet precise, marking the point of entry with quiet confidence.
Designed to seal drain inlets and return lines, it suits plumbers and homeowners alike who need a reliable plug for pools, sinks, or pressure testing without complex machinery.


02MATERIALS
Robust metal and high-grade rubber
The construction pairs a durable metal exterior with an inner layer of high-grade rubber. This combination provides the necessary expansion force to create an airtight seal against the pipe wall. The materials are chosen for stability, ensuring the cap maintains its integrity during repeated cycles of compression and release.

04DETAILS
Stainless wing nuts for easy grip
Traditional plastic fasteners are replaced here with stainless steel wing nuts, offering increased stability and durability. These allow for simple installation without additional tools; the user can tighten the mechanism by hand until the rubber expands fully. The black and silver finish remains distinct, though light reflection may cause slight visual variation on different displays.
FIT
Three inches of precise coverage
Sized at three inches, the cap accommodates most standard piping systems found in residential and commercial settings. The measurement allows for a tolerance of plus or minus one to three centimetres, accounting for manufacturing variances. The package contains only the assembled cap, ready for immediate use in safeguarding plumbing infrastructure.
