HDSD<br />

The HDSD seal types are designed with dual<br />

sealing elements with lips facing in opposite<br />

directions. This style is used for applications<br />

requiring the separation of two fluids. When<br />

using an HDSD seal, it is very important to<br />

provide a means to lubricate the sealing<br />

elements (i.e. the cavity between the sealing<br />

elements may be packed with grease or holes<br />

may be drilled from the outer diameter into<br />

the cavity between the lips).<br />

HDSD<br />

HDSE<br />

This style features dual elements with lips<br />

facing in the same direction. This seal type is<br />

used where a back-up seal is desired for<br />

retention or exclusion purposes. As with the<br />

HDSD type, a means of lubricating the <strong>seals</strong> is<br />

necessary for a proper sealing function.<br />

Available sizes<br />

The HDSD and HDSE seal product lines are<br />

available in sizes ranging from 203 to 1 346<br />

mm (8 to 53 in) (Table 20 on page 211).<br />
