Use these test kits to check for leaks in your AN hose assemblies. Simply screw the straight plug into one end and the specially designed valved plug in the other, charge the line with a compressed air source and submerge in a water bath to detect any leaks. Includes one plain plug and one valved plug.
Note: These test kits are for low-pressure bubble testing only. Very large assemblies or hoses which will see very high pressures should be hydrostatically tested using a non-compressible fluid.
We also offer all 7 sizes together in our Complete AN Hose Pressure Testing Kit (Part No. 3273).
