Omniseal Solutions' large diameter seals with a reduced rod gland have a diameter > 4” (101.6 mm).

Handling

*Whenever possible, you should handle and install the seal in a DRY environment with no wind or dust.

Name Description

1

Clean the gland with an appropriate solvent and a clean wipe. Inspect the gland for nicks, dirt, burrs, indentations, and sharp edges. Address these as needed. If the seal needs to pass over sharp edges, threads, etc., additional installation instructions and tools may be required.

2

Clean a table and put an appropriate protective paper over the surface. Put on clean, lint-free soft gloves to protect the seal and gland. Keep the gloves on until the seal is fully installed. Carefully unpack the seal and place on the table.

3

Remove the seal from the individual container or bag. Use a pair of scissors if required but take care the sharp ends do not make contact with the seal.

4

Take a soft, lint-free cloth and wipe the seal. If you notice a scratch or any other damage on the seal, please do not install the seal and contact Omniseal Solutions immediately at [email protected] or your following local customer service areas:

Position seal in front of gland and slowly push the seal into the gland (Figure 1 below), using both hands to push along the circumference until completely installed (Figure 2 below). The seal may be installed heel or spring cavity first, but it should align with your company's assembly instructions and diagrams. Check that the seal is properly seated in the gland.

Check the counterpart mating surface for scratches, inadequate surface finish and/or damages. If anything is noted, please do not continue with installation.
