The Installation Tool consists of a collar made from an impact resistant material which is profiled to suit a particular seal. The tool 'clips' over the seal face, protecting the lapped surface and resting on the O-ring (Fig. Installation Tools are designed to locate on the O-ring so that as force is applied.
• O-Ring sizing cones and measuring tools
To install an O-Ring energized piston seal into a closed groove with tools, first insert the O-Ring into the piston-seal groove using the method described above. Then place an installation cone over the piston and align it with the seal groove.

Incorrect O-ring installation can lead to assembly damage causing leakage during the first pressure test. If the system does not pressurize properly, the entire piece of equipment should be disassembled and seals must be replaced. Depending on when this test occurs, multiple manufacturing steps could be in between the seal installation and the first step where leakage can be identified. If O-ring damage happens with high frequency, you could be wasting time and money on seal replacement. Luckily, there are some easy steps that can be followed to help prevent this from occurring. Parker's recommended guidelines for installation include always using lubrication, good gland design, and ensuring correct sizing.
Lubrication Makes Installation Easier
Using lubrication is an essential facet of proper installation. Lubrication reduces surface friction between the O-ring and mating surfaces, allowing the O-ring to seat in the groove with very little difficulty. Ilivid apps. In male and female radial seals, lubrication will reduce installation force and create a smooth transition as the piston is inserted in the bore.
Choosing the proper lubricant requires careful consideration of your system. You must ensure the lubricant choice is compatible with the material being used, suitable for the temperature range of the application, compatible with the system fluids, capable of producing a high surface tension film, and does not clog system filters.
Parker offers two lubricants, O-Lube and Super-O-Lube. The O-Lube is an outstanding general-purpose grease intended for O-ring and elastomer seal types used in hydrocarbon service. O-Lube has a recommended service temperature of -20°F to 180°F (-29°C to 82°C). On the other hand, Super-O-Lube is an ideal all-purpose O-ring lubricant. Rather than a grease, the Super-O-Lube is a high viscosity silicone oil. It is an extremely effective seal lubricant, useful from -65°F to 400°F (-54°C to 204°C).
For more information on Parker O-Lube and Super-O-Lube and how to choose a lubricant, refer to section 3 of the O-Ring Handbook.
Good Design Principles
One of the easiest ways to ensure care-free installation is by following good design practice as recommended in the Parker O-Ring Handbook. The dimensions listed in the O-Ring Handbook put good compression on the O-ring while preventing the groove from exceeding 100% fill. In radial seal applications Parker recommends using a lead in chamfer at an angle of 15-20 degrees with an opening which exceeds the maximum height of the O-ring in the groove.

Proper Sizing is Key
Putting the wrong sized O-ring into an application can also lead to damage, making it important to verify sizing to ensure the right O-ring was selected. Unfortunately, measuring O-rings in the field or in a warehouse is not easily done without the proper tools. Parker offers a unique solution to this problem by offering measuring cones and circumference 'Pi' tape to help provide quick and easy sizing information. These tools will help ensure that the proper Parker standard size is chosen during assembly.
