many piping applications including compressed air, plant cooling water, welder water, chilled water, machine
service piping, machine oil piping and solvent lines.
For services not listed or special services, contact Victaulic for recommendations.

butnot corrosive to an O-ring may result in a premature system malfunction.

WARNING Mark the pipe to ensure that it is fully inserted into the fitting before pressing. When full insertion into the fitting is achieved, the insertion mark will be visible at the end of the fitting. Failure to do so could result in joint leakage or joint separation, property damage and personal injury. ALWAYS MARK THE PIPE! |
WARNING Before assembling Pressfit System products and operating the Pressfit Tool, carefully read and understand the Pressfit System Product Assembly and Tool Operation Manual supplied and available at no cost from your Victaulic representative, branch or stocking distributor. Failure to do so could result in personal injury, improper installation, leakage or joint separation and property damage. |
