V-Seals and V-Rings

Keep Out Contaminants

Versatile V-seals and V-rings offer all rubber, one-piece construction of resilient seals, extending bearing and shaft performance while protecting rotary shafts from dirt, water and contaminants. The one-piece rubber seals are mounted on a shaft to keep water, dirt and other materials from entering bearing housings. The V-seal’s self-adjusting lip rotates with the shaft against the counter face bearing housing or shaft collar to produce the dynamic sealing. The rotating peripheral shaft speed causes contaminants to be blocked while dirt and water are not able to attach to the flexible sealing lip.

V-seals are formed into different profiles based on the shaft size to be sealed, available mounting space, as well as the applications. Usually constructed of Nitrile rubber (-40°F to 212°F/-40°C to 100°C) or FKM fluoroelastomers (-15°F to 390°F/-26°C to 199°C), V-seals can be made to order with special sizes or configurations. V-rings are easily installed by stretching over flanges for minimal disassembly and offer extremely low heat build-up and low torque drag. The V-seals do not need excessive countersurface preparation or expense to create optimal sealing.
