About Us
Since our inception in 1950, General Rubber Corp has designed and developed a wide range of mechanical rubber products used in the most demanding applications. Improved performance and engineered solutions have often been accomplished by incorporating advanced materials and technologies to what otherwise would be considered a conventional product line. That is the General Rubber difference and the principle reason why our products range “From the simple, to the simply amazing”.
The Maxi-Joint brand represents our comprehensive line of expansion joints, flexible connectors, rubber flanged hoses and related accessories, as well as spray shields and penetration seals. These products provide critical functions in piping and ducting systems including absorbing thermal movements, ground settlement, misalignment, noise, vibration and shock.
The Flex-Valve brand represents our state of the art line of pinch valves, pressure isolation rings and duck bill check valves. These products are uniquely suited for slurries and other difficult fluids, and can out perform alternative products 10 to1. They are abrasion and corrosion resistant, non-clogging, maintenance free and can even seal drop tight around solids.
The SoundZorber brand represents our complete line of noise and vibration control products, as well as, seismic restraints. The knowledgeable implementation of our resilient mounts, hangers and pads can virtually eliminate objectionable noise and vibration. Our seismic cable and snubber restraints are designed to protect both life and property in the event of an earthquake.
High-quality General Rubber products solve problems in a remarkable number of applications, from electric boats to paper mills to major resort hotels. We have been audited and approved for use by the Nuclear Procurement Issues Committee (NUPIC). Nuclear and other power generating facilities select General Rubber because performance and reliability are critical.
As the pollution abatement and waste water treatment industries came of age, General Rubber responded by developing corrosion and abrasion-resistant products to meet their specific requirements. Similarly, chemical processing plants, paper mills, and mining operations have learned that they can depend on General Rubber products.
Milwaukee Park Stadium and many other commercial and industrial venues use General Rubber vibration control products for their heating, ventilation, and air conditioning (HVAC) systems to relieve stress and absorb objectionable noise and vibration. Ships, including the USS Cole, use General Rubber expansion joints to save space, reduce noise, and isolate vibration.
The General Rubber customer commitment is evident in every aspect of our business. Our sales team includes engineers who are prepared to discuss the intricacies of the application. They know what questions to ask to identify the best solution at the best price. If an effective solution cannot be obtained from our extensive product line, our professional engineers will custom design a solution optimal for your application. This willingness to search for answers is deeply ingrained in our customer commitment and lies behind our tradition of releasing new and innovative products each year.
Once an order is placed, products are meticulously designed, fabricated and tested for long life and reliable service. Our full product guarantee is a reflection of the pride and confidence we take in the quality of our products.
The General Rubber team is also adept at expediting design and manufacturing so that orders arrive in spec, on time and under budget. Our ability to consistently exceed customer expectations was validated when we became the first in our industry to earn ISO-9001 certification. We may have also been the first to utilize the most comprehensive set of 2D, 3D and Finite Element Analysis (FEA) Software to design, simulate and visualize new and existing products. Our facilities are open to our customers and their third party inspectors. We are proud to comply with international standards including but not limited to, the Pressure Equipment Directive (PED); with audits by ABS, TUV, and GL to name a few.
General Rubber is committed to the advancement of knowledge in the field. We are a founding and active member of the Fluid Sealing Association (FSA) and are active in other industry associations including the International Society of Automation (ISA) and the American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE). We regularly make engineering presentations on our full range of capabilities and have published numerous articles on the subjects. General Rubber stands tall as the industry leader and our global business is based on engineering excellence, responsive service and reliable quality.
Thank you for your consideration.
Warm regards,
