Draper Expert Universal Cooling System Pressure Test Kit (5 Piece)

Keep your engine running cool and catch costly leaks before they become serious problems with the Draper Expert Universal Cooling System Pressure Test Kit (URPTK). Designed for professional mechanics and serious DIY enthusiasts alike, this 5-piece capless testing kit makes cooling system diagnostics straightforward, accurate, and reliable.

Capless Universal Design – Fits More Vehicles

Unlike traditional radiator pressure testers that rely on cap-specific adaptors, this kit uses an innovative universal cone adaptor system that seals directly into the coolant reservoir or radiator filler neck. With four cone adaptors covering sizes from 17mm up to 48.5mm, this kit is compatible with a wide range of cars, vans, and light commercial vehicles – including both screw-type and bayonet-type cap fittings. No more hunting for vehicle-specific adaptors.

Simple, Controlled Pressure Testing

The hand-operated pressure pump features an integral pressure gauge, allowing you to build and monitor system pressure with precision and control. Quickly identify leaks in hoses, radiators, water pumps, head gaskets, and expansion tanks without the need for expensive diagnostic equipment. A built-in quick connector makes attaching and swapping adaptors fast and effortless.

Safe Depressurisation with Release Pin

Safety is built in. The integrated pressure release push pin lets you safely depressurise the cooling system before removing the adaptor – protecting you from scalding coolant and preventing damage to components.

Rugged Storage Case Included

All five components are housed in a sturdy blow-moulded plastic carry case, keeping your kit organised, protected, and ready for use in the workshop or on the road.
