Heavy-Duty NMO Antenna Mount EPDM Rubber Gaskets, 1" ID x 1.5" OD x 1/8", 5 Pack

For the 1/8" Heavy-Duty version, I'd make the description emphasize the extra thickness instead of simply changing the dimensions. Heavy-Duty NMO mount rubber gaskets designed for sealing standard 1" antenna mounts on vehicles and equipment. Made from premium EPDM 60A rubber, these gaskets are 2X thicker than standard 1/16" versions, providing increased cushioning, improved paint protection, and reliable all-weather waterproof sealing. 1" inner diameter, 1.5" outer diameter, and 1/8" thickness ensure a secure fit while helping protect vehicle roofs from vibration, compression, and water intrusion around NMO antenna mounts. Ideal for automotive, fleet, off-road, marine, motorcycle, CB, HAM, GMRS, scanner, and public safety radio installations where additional sealing and cushioning are desired.
