The Monument 174Z Air Testing U-Gauge Kit is a comprehensive air testing solution designed for testing drains and pipework to 100mm water gauge pressure. This professional kit provides plumbers and drainage contractors with all the essential components needed to carry out accurate pressure testing on any size of drain or pipe, with the exception of testing plugs which are selected separately based on the specific application. Housed in a practical display box with full instructions, this kit ensures organised storage and easy portability between job sites. The included U-gauge delivers precise pressure readings, whilst the hand bellows pump allows for controlled pressurisation of the test system. The kit's versatility is enhanced by the inclusion of multiple BSP nipple caps in both 1/2in and 1in sizes, accommodating different pipe diameters and connection requirements. The Y-piece connector and three 600mm rubber hoses provide flexible configuration options for various testing setups.
