Custom Molded Rubber Products — Industrial Rubber Manufacturing & Engineered Components Built to Spec in the USA

At Holz Rubber, we specialize in custom molded rubber products engineered for performance in demanding industrial applications. As a trusted rubber manufacturing partner in California, we design and produce high-quality molded rubber components using advanced compression molding, transfer molding, and bonding processes. From rubber bonded to metal and rubber bonded to plastic assemblies to precision-molded sealing elements, valve seats, and vibration isolation components, every product is built to your exact specifications—material, geometry, tolerance, and performance requirements.

Whether your application involves oilfield equipment, mining operations, agriculture machinery, processing systems, or industrial equipment, our team delivers durable, high-performance rubber components designed for long service life in harsh environments—abrasion, pressure, chemicals, and extreme temperatures.

Custom rubber manufacturing involves designing and producing elastomer components tailored to specific applications when off-the-shelf parts are not sufficient. Through precision rubber molding and engineered material selection— including EPDM, natural rubber, neoprene, and nitrile— we create components that provide sealing, vibration isolation, impact resistance, and chemical compatibility. With in-house engineering, mold design, and production capabilities, Holz Rubber ensures every component meets the functional demands of your system while maintaining consistency, durability, and cost-efficiency.
