The H Type oil seals from DSH Seals are spring energized radial lip seals designed for high performance applications. These seals feature precisely calibrated springs that continuously exert pressure on the sealing lips, keeping them firmly engaged on the shaft.
When considering a rotary service seal and additional gland length is available, an O-Ring Heel Seal provides a level of anti-rotation and redundant sealing. The addition of an O-Ring on the heel of a radial seal creates a high friction interface at the bore to counteract rotary forces. With proper hardware design, a high level of sealing can be realized, making an O-Ring Heel Seal a good choice where gaseous or low viscosity fluids need to be sealed.
Single-Lip V-Spring-loaded rotary shaft seal for extreme environments.
This seal is designed to provide long service life and low friction for extreme service applications over a wide temperature range.
This seal is for high PV applications characterized by high pressure and low speed. This seal has a relatively small axial length and is available in many materials specially suited to handle aggressive chemicals and environments.
