TT797 RT-919J Radiator Cap Pressure Tester Kit 9 Adaptors Hand Pump

🔧 Product Overview

Unbranded RT-919J-pattern radiator cap pressure tester kit designed to check whether a radiator or coolant expansion-tank pressure cap seals correctly and releases pressure at the specified rating.

The radiator cap is fitted to the corresponding adaptor, which is then connected to the hand pump. Pressure can be applied gradually while monitoring the gauge to identify caps that leak, fail to hold pressure or release outside their intended operating range.

This kit is specifically for testing radiator pressure caps. It is not the same as a cooling-system pressure tester used to pressurise the complete vehicle cooling circuit.
