Custom Polyurethane Bushings and Rubber Grommets
Seal Science is an industry leader in custom rubber products. We have the ability to design and manufacture custom rubber grommets and custom polyurethane bushings to fit your specific application in any shape, size, and material. We specialize in high precision tolerances, but also manufacture to commercial and less demanding tolerance configurations as well.
Basic rubber grommets are used to protect items (normally wires or pipes) from sharp edges while passing through a walled area. Many grommets can also provide an environmental seal, and more advanced designs can even be used in firewalls rated to withstand temporary temperatures of up to 2000°F. These rubber products are hand fabricated with fabric reinforced rubber to withstand these temperatures.
Rubber bushings are used to reduce vibration, absorb shock, and resist abrasion in an assembly. Custom polyurethane bushings are widely used in the automotive industry because of their added high load bearing capacity, high tear and cut resistance, resistance to water, grease, oil & ozone, and a higher compression set.
Bushing and Grommet Materials
Our custom rubber products can be made in a wide range of materials: silicone, Fluorosilicone, polyurethane, EPDM (Ethylene Propylene), fluorocarbon, nitrile, neoprene/chloroprene, natural rubber and more. You can provide the drawing and specifications for your part, or we can design a custom molded product to fit your requirements.
Each of these materials has its own unique place within the sealing industry and each has benefits or downfalls depending on the application. If you are unsure which material would be best for your specific application, contact us and we will be able to point you in the right direction.
