Jonal Laboratories
High Temperature Silicone Rubber Seals & O-Rings for Aerospace
Design Assistance


Our test lab is capable of determining the physical, rheological, thermal, and fluid
resistance properties of materials per ASTM, military, AMS and other test methods. We can perform standard tests in house, as well as set up specialized custom tests for development projects. We are one of a few labs capable of doing full testing to AMS7273 including the component seal test. 

We provide release tests with every lot shipped, and test the physical properties of each batch of compound to assure product consistency and closely monitor blueprint and specification requirements to assure full compliance to customer requirements.   It is a common practice of ours to take incoming raw material to the lab to test and verify key data assure optimum output characteristics.
