Learn More About General Rubber’s Style 1101 Wide Arch Rubber Expansion Joint

General Rubber’s style 1101 wide arch, rubber expansion joint can be utilized in a variety of applications.  When specifying the 1101, be sure to include the following.

The unrestrained rubber expansion joint shall have a single flowing arch. This profile provides exceptional all directional movement while virtually eliminating sediment buildup.

The inner tube shall be a seamless, leak-proof layer of nominal ¼” thickness that extends from the outside diameter of one flange to the outside diameter of the other flange.  It shall be an elastomer compatible with the fluid media and service temperature.  The textile reinforcement shall be a minimum of six bias plies of high quality tire-cord reinforcement, having a adhesion promoting resorcinol formaldehyde latex (RFL) coating and impregnated (skimmed) with a compatible elastomer to ensure a homogeneous bonding to other layers.

The metal reinforcement shall have sufficient radial strength to support the textile loads.  It shall be high-tensile steel to keep weight and volume down to optimize flexibility.  The metal reinforcement shall be round to prevent cutting of the textile reinforcement.  The exterior cover shall be a seamless layer, of nominal 1/16″ thickness.  It shall be an elastomer compatible with the external environment. When required an additional exterior coating shall be applied to improve the external weathering protection.

Rubber flanges shall be integral with the body and have a full flat face with the same outside diameter as the mating flange.  Flanges shall be drilled to Class 150 lb., or as specified.  Retaining rings shall be fabricated of minimum 3/8″ thickness high grade carbon steel or ductile iron with hot dipped galvanized finish.  Alternative materials and finishes are available upon request.
