Style B-11 Vegetable Fiber Sheet
Style B-11 is a general purpose vegetable fiber sheet for flange gasketing where the maximum temperature does not exceed 250°F(120°C). It meets the requirements of HH-P-96F Type 1.
Services include oil, greases, water and light hydrocarbon liquids.
Standard Thickness are 1/64" (0,4 mm), 1/32" (0,8 mm), 1/16" (1,6 mm), 1/8" (3,2 mm). All thicknesses are supplied in rolls of 25 yards (22,8 m) X 36 inch (0,95 m) Width.
Style B-81 Greenshield™ Aramid Fiber Nitrile Bound Gasket Sheet
INDUSTRIAL Brand™ Greenshield™ Sheet Packing offers superior performance with the widest range of applications available in one gasket material. This nitrile rubber bound sheet gasketing, composed of chemically stable and heat resistant fibers provides outstanding creep resistance at high temperatures and high load to give maximum safety, torque retention and sealing characteristics. Chloride content below 100 ppm reduces flange corrosion which, when combined with the nonstick properties of this material, lowers maintenance and down-time.
Services INDUSTRIAL Brand™ Greenshield™ Sheet Packing is intended for all general mill uses.
Applications Greenshield™ is compatible with the following applications: Gases, water, steam, inorganic salt solutions, organic acids, alkalies, alaphatic and aromatic hydrocarbons, oils, greases, heat transfer oil, and refrigerants.

This test was developed to assess the behavior of gaskets when subjects to surface stress in cold and hot conditions. In this test the load is maintained as the gasket relaxes and the temperature increases. This subjects the gaskets to more severe conditions than the ASTM F 38B test. Measurements are made of the decrease in thickness under a load of 3625 psi at a temperature of 73°F and the additional decrease in thickness caused by heating to 572°F under constant load.

Key-lon Gasket Material
Rubber Sheet Packings
We supply the highest quality rubber sheet packings in three standard materials. They are furnished in rolls of approximately 100 lbs. (45,4 Kg) each. (1/4" thickness is in 200 lb. (90,8 Kg) rolls).
STYLE 370 NEOPRENE SHEETNeoprene sheet is formulated for its high resistance to oils and solvents and may also be used on water and low pressure steam when a single material for these services is desired.
STYLES 1100 AND 1150 RED RUBBER
Style 1100 is a commercial grade red rubber with a cloth finish. It is intended for water or oil service to 250°F (120°C). Style 1100 is also available in 48" (1,21 m) width
.Style 1150 is a premium quality smooth finish red rubber which provides extended service life when used as flanged joint gaskets or as pump gaskets in either water or oil services to 250°F (120°C).
STYLE 1170 EPDM SHEET
EPDM sheet is the ideal steam resistant material for manhole/handhole gaskets in heating boilers.
STYLE 1260 NEOPRENE DIAPHRAM SHEET
Style 1260 cloth inserted neoprene diaphram sheet is designed for general service in water, air, steam or oils. It is widely used in reducing and regulating valves. There is one ply of reinforcing cotton duck fabric for each 1/16" (1,6 mm) of thickness.
STYLE 1265 NYLON REINFORCED NEOPRENE DIAPHRAM SHEET
Style 1265 is constructed in the same manner as Style 1260 above with the substitution of high strength nylon cloth for the usual cotton duck. This provides a much higher strength material.
