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. This master kit includes plugs for 3AN, 4AN, 6AN, 8AN, 10AN, 12AN, and 16AN hose ends. We also offer each size of AN Pressure Test Plugs individually (Part No. 3272-Size).
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.
