Introduction: With the economic

and environmental climate of today it is more

important than ever to prevent leakage in

your carrier system. Flanges, the most

Nut Bolt - Stud Insulating Insulating Steel Nut
Sleeve Washer Washer common trouble area, need to be sealed

properly to prevent this leakage and must also

be cathodically insulated to prevent stray

currents which cause undue corrosion and

eventual breakdown of the metal.

Advance Products & Systems manufactures

and maintains a supply of quality products and

materials which can help solve most flange

sealing problems to prevent leakage,

preventing corrosion, and saving the integrity

of the pipeline.
