Manufacturing Guide for Elastomeric Seals

Abstract

Elastomeric seals used in gun mounts have a hard to achieve combination of properties, so acceptable seals are difficult to procure and few sources are available. Therefore, two rubber formulations were developed, each for a different hydraulic oil, with the intention of providing the manufacturing data to U.S. Government activities and potential vendors. As in-house Army fabrication capability is needed for the seal kit for the M140 gun mount, polytetrafluoroethylene (PTFE) tubes and cloth filled phenolic sheet were procured for back up rings in the kit. Subsequent gymnastication demonstrated Rock Island Arsenal has the capability of fabricating all the seals in the kit according to the technical data. For improved producibility and storage and lower cost, nylon filled phenolic and polyester thermoplastic back up rings were fabricated to replace the phenolic and PTFE, respectively.
