Fully cured extruded cord is typically cut to length with a 45 degree angle scarf cut ends. A proprietary process is performed to bond the ends with a rubber and adhesive mixture that results in a much cleaner joint than Standard methods. The consistently cleaner joint allows for better sealing with less leak potential which can be used in higher performance applications. Good joint tensile strength can be achieved with Buna-N, Neoprene and EPDM, reasonably good with Viton and only fair strength can be expected with Silicone. Great for prototyping before migrating to Continuous Molding method. ID dimensional tolerances per RMA Table 18, S1 Precision or better.
Potential for slight adhesive excess at joint (Exaggerated Renderings to describe potential issues)
Potential slight misalignment
Buffing at the joint can yield variable surface finish from the rest of the part
