Pin-Point is ideal for checking all gas or air pressure fittings and joints or for rapid and safe detection of even the minutest leak. Pin-Point is effective even at extremely low pressure percolation. Pin-Point contains no alcohols or solvents, is non-caustic and contains a rust inhibitor. Pin-Point should be sprayed directly onto the suspect area using the extension tube. Examine for bubbling which will indicate any leakage. Pin-Point is ideal for the location of leaks in commercial vehicle air brake systems, gas and air-line pipe systems, pressure vessels and pressure testing of other equipment and pipework.
