Knauf 1000° Pipe Insulation

Proto PVC Fitting Covers




Description - The Proto® Fitting Cover System consists of one-piece, pre-molded, high-impact PVC fitting covers with fiber glass inserts and accessories. Accessories are elbows, tee/valves, end caps, mechanical line couplings, specialty fittings, jacketing, tacks, and PVC tape.



Application - The Proto Fitting Cover System is used to insulate mechanical piping systems at fitting locations. It provides PVC jacketing for straight run piping and gives a quality appearance and excellent durability.







Features and Benefits:
Fire and Smoke Safety
  • Proto PVC Fittings do not exceed 25 Flame Spread, 50 Smoke Developed.
  • Roll jacketing is available in 25/50-rated or indoor/outdoor grade.
  • The 25/50 products meet most fire and safety requirements of federal state and local building codes.


UV Resistant
  • Use indoors or outdoors.
  • Paint outdoor fittings to enhance UV and colorfast protection.


Excellent Appearance
  • Bright high-gloss white coloring adds a distinct quality appearance to the system.


Easy to Clean
  • The smooth high-gloss surface cleans easily with soap and water.
  • Ideal system for food and drug facilities.


Low-Cost Installation
  • Significant cost savings vs. conventional cement, molded sections and mitered sections.


Fast and Easy
  • At fitting locations, the fiber glass insert is wrapped around the pipe fitting, the Proto PVC Fitting is applied over the insert and then tacked or taped.


Wide Temperature Range
  • For mechanical piping systems operating to 500°F (260°C)


Long Lasting
  • Can be used more than once on retrofit projects, general maintenance.


Excellent Thermal Value
  • Low thermal conductivity value of 0.26 at 75°F (0.037 W/m2•°C) mean temperature.
  • Better thermal efficiency than conventional cement fittings.


Resistant to Fungi and Bacteria
  • Does not promote growth of fungi or bacteria.
