Quad seal (also called X seal) for M35A3 CTIS hubs. Sold individually. Two are used in each hub. P/N RCSK16048-2 also replaces Q-4235-523MZ, 12448547. NSN 5330014491978.
Service note: indications that a quad seal needs replacing are air escaping from axle vents, a CTIS system that is very slow to build tire pressure, or audible air hissing out at a hub. If the tire fails to remain inflated this seal is not causing the problem.
Limited to current inventory.
