Rothkopf has been in the rubber parts business since 1956. We are well-respected in the industry for our longevity, but also for the things that led to this long-standing position, like our specific subject matter expertise, superior service, fair pricing, and fulfillment solutions that reduce risk and cost.

Your source for Custom & Specialized Rubber Assembly Components

The custom molded rubber components we provide to our customers are uncommon and vary from customer-to-customer, but nearly always have these things in common:

  • Critical to system operations in a demanding application environment
  • Required to comply with stringent material specifications / agency approvals
  • Among the lowest cost components in the system
  • A likely point of failure
  • The most visible at failure

Rothkopf understands the unique and often competing application requirements that impact molded rubber part design. We have decades of experience in getting our customers the ideal part for their exacting requirements. We listen, question, and challenge (when necessary) to gain command of the application environment. Understanding that, we leverage our supply chain network to collaborate and compete to identify the best source to engage. When the part is won, we build inventory and a pipeline that flexes to support varying production requirements, resulting in a flawless fulfillment solution that reduces risk and cost. Whenever you need us, we’ll bring our expertise and global network of resources to your table. Reach out to Rothkopf today and let’s get to work.
