Using the handbook in your drawings
The handbook sets common tolerance classes for molded and extruded rubber. Quoting a class on your drawing, instead of tight tolerances on every dimension, lowers cost and avoids disputes.
Reserve tight tolerance for sealing surfaces and mating features, and use the standard class elsewhere. See RMA Tolerances for the tables. Our engineers can review a drawing against it. Send a drawing or sample through the quote form and we will review it with you.
