Automotive pipe plug kit PipeStoppers
12 mm - 50 mm (0.5" - 2")

Automotive Plug Test Kit
To make the sealing of all holes easy and fast for reliable leak testing for a variety of heat exchangers, particularly radiators and inter-coolers for cars and trucks, the Pipestoppers™ division of Huntingdon Fusion Techniques Limited manufactures ready made kits of plugs.
The plugs are made from nylon and natural rubber, so they will not corrode and seize up. They can also be totally dismantled for cleaning and part replacement.
Each kit comprises two of each solid shaft plugs, from 0.5" to 1.5" and hollow shaft from 0.5" to 2". Also included are 4 x 0.5" BSP nipple caps and 4 x 0.5" BSP swivel nuts and hose tails. Plus the rigid ABS plastic storage case, with special cut to size foam.
For larger diameters, see the details of the Commercial Vehicle leak test kit. All plugs are available as individual items for replacement purposes.
Sizes from 1.5" and above have an 0.5" BSP threaded hollow shaft connecting air lines to pressurise the items under test.
