How To Install Omniseal® Large Diameter Spring-Energized Seals in a Reduced Piston Gland

Introduction

Designing a precision seal or material solution is critical; just as critical is the installation. Prepare for success by watching the following installation video and downloading the corresponding seal handling and installation instructions below. This pdf file can also be downloaded from our document center along with other technical materials related to industries, solutions or materials. Contact our team for questions or additional support.

Omniseal Solutions' large diameter seals with a reduced piston 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 (Figure 1 below) and slowly push the seal into the gland, pushing over and past the retaining lip (Figure 2 below). Use both hands to push along the circumference until seal is completely installed (Figure 3 below). Seal should be installed heel first and 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.

Carefully bring both hardware components together (Figure 4 below), watching that the seal is position correctly in the gland.
