V-Seal Engineering Made Simple
GBSA V-Seals are simple. Simple to order. Simple to install. Simple to operate.
Our engineers designed one-piece, all-rubber rotary shaft seals to stretch to fit virtually any shaft. No matter the material or alignment, you’ll get a tight, contaminant-stopping seal that will not only meet, but exceed your quality and performance needs.
On the rare occasion that we don’t have a mold for your specific size, we have the capabilities to vulcanize our seals or make a tool for the size you need.
Parts of the Rotary Shaft V-Seal
The v-seal is comprised of three basic parts.
- The body of the seal holds it in place on the shaft or mounting surface.
- The cone shaped flexible lip rides in light contact with the counter surface and does the sealing.
- The resilient hinge joins the body and lip together, providing the force required to keep the lip against the counter surface.
Rotary Shaft V-Seal Installation
Easily installed by hand and held in place by their own tension, they can be used as a primary or secondary seal for an oil seal, mechanical seal or labyrinth. Ideal for preventing dirt, water or oil contamination, v-seals are also superb crease retainers.
All rubber, the v-seal can stretch to 40% of its molded I.D., so it can easily be stretched over flanges, collars and entire bearing housings during assembly. The same resiliency holds the seal in place without the need for springs or clamps.

Rotary Shaft V-Seal Function
- Used alone, the v-seal keeps lubrication in and contamination out.
- Acting as a slinger, the v-seal lip keeps dirt and water out and grease in.
- Secondary seal for oil seal, mechanical seal or labyrinth.
- Acts as check valve during grease purging.
Rotary Shaft V-Seal Selection
There are several factors that must be considered when selecting a v-seal, including:
- Shaft Finishes
