Larsen NMO O-Ring Kit

In order to protect your NMO antenna from moisture leaks the O-ring is an essential part of the antenna base. When your O-ring becomes brittle and weathered it is time to replace it. Do not let a mechanical gasket failure degrade your antenna performance or allow water to leak in at the base of the NMO mount.
