Installing a rotary seal correctly is crucial for its performance and longevity. Based on the provided reference, one method involves using a plastic hammer.
To install a rotary seal, you can use a plastic hammer, gently tapping on the seal 180 degrees apart to ensure it is fitted properly in the housing while avoiding damage.
Rotary Seal Installation Method
Ensuring the proper installation of a rotary seal prevents leaks and extends the life of both the seal and the equipment it protects. A common method, highlighted in the reference, involves careful use of hand tools.

- Method: To install the seal with just a plastic hammer, gently hammer on the seal 180 degrees apart as shown to avoid damage to the seal. Also, check that the seal is fitted properly in the housing.
Steps for Installation (Using Plastic Hammer Method)
Here's a breakdown of the installation steps based on the provided reference:
- Prepare the Housing: Before installation, ensure the housing bore is clean and free from debris or sharp edges.
- Position the Seal: Carefully place the rotary seal into the housing bore, ensuring it is aligned correctly.
- Gentle Tapping: Using only a plastic hammer (metal hammers can easily damage the seal), begin to gently tap the seal into the housing.
- Alternate Tapping Points: The reference specifically advises tapping the seal at points 180 degrees apart. This alternating method helps the seal enter the bore evenly and prevents it from tilting or binding.
- Check Fitment: Periodically, or once the seal appears seated, check that the seal is fitted properly and is flush or at the correct depth within the housing.
- Continue until Seated: Continue gently tapping at opposite points until the seal is fully and properly seated in the housing.
Important Considerations:
- Always use a plastic or rubber hammer.
- Apply gentle, even force.
- Alternating tapping points (180 degrees apart) is key for even installation.
- Avoid hitting the sealing lip directly.
- Ensure the seal is seated squarely and to the correct depth.
Proper installation using this method minimizes the risk of damaging the seal during fitting, which can lead to premature failure.
