Mil-Spec Rubber » Military Rubber Specification, Military Grade Rubber, Mil-Spec

As technology changes so does our designs and manufacturing methods for producing military grade / mil-spec rubber o- rings, seals, tubes and other molded rubber products. Datwyler offers many types of seals and sealing devices that meet the numerous military rubber specifications, ensuring our compounds will withstand the aggressive environments they will endure. Seal performance is particularly affected by these drastic temperature variations. Datwyler's military compounds can be used in applications with continuous service temperatures as low as -60ºF and as high as 401ºF. See chart below for military specifications and corresponding Elastomer's.
