JOB ONE: Maintenance Excellence

Maintaining hundreds of millions of dollars worth of fighter jets in mission-ready shape takes a serious amount of teamwork. As a crew chief or tactical aircraft crew member, your role is to insure mission-readiness, streamline maintenance efforts and resolve any problems you might identify. At MIL-COMM, we have created TW25B®, an extreme performance synthetic lubricant that supports your mission.

What is TW25B®?

No matter how smooth a metal surface might feel, there are imperfections and microfractures on the surface of all metals. TW25B® synthetic grease significantly reduces friction and wear on all working parts, penetrating metal surfaces and leaving a semi-dry film coating for smooth functioning and extended life of metal parts. Our technology deeply penetrates the surface, filling the micropores and bonding to the metal to perfect and protect. Tested and used by all branches of the U.S. military and by major manufacturers. All-synthetic, used safely worldwide since 1987.
