Miscellaneous Rubber Shapes & Custom Profiles
Our miscellaneous rubber shapes category features a comprehensive selection of specialized profiles designed to meet unique sealing, weatherstripping, and edge protection requirements across diverse industries. These custom-shaped extrusions go beyond standard O-rings and channels to provide solutions for complex applications where off-the-shelf components fall short.
From H-strips and L-strips used in construction and transportation applications to T-strips and P-strips essential for weather-tight sealing, our extruded profiles deliver consistent performance in demanding environments. Each shape is precision-manufactured to exact specifications, ensuring dimensional accuracy and material consistency for reliable long-term service.
Available in multiple rubber compounds including EPDM for superior weathering resistance, neoprene for moderate chemical exposure, silicone for high-temperature applications, and PVC for cost-effective general use. Our extrusion capabilities allow us to create custom profiles tailored to your specific dimensional requirements and performance specifications.
Whether you need standard catalog items or custom-designed profiles, our technical expertise and manufacturing capabilities ensure you get the right rubber shape solution for your application, backed by our commitment to quality and customer service.
