Defense Innovation DI68 / Milsig T17 Seal Kit

The Defense Innovation DI68 / Milsig T17 Seal Kit is a replacement O-ring kit for compatible DI68 and T17-based systems.

O-rings help keep air inside the launcher.

Over time, seals can wear, flatten or become damaged. This can cause leaks or poor performance.

Replacing worn seals can help restore a proper air seal.

What Does the Seal Kit Do?

The kit contains replacement seals used in the launcher air system.

These seals help stop air from escaping.

A worn O-ring can cause:

• Air leaks
• Loss of pressure
• Poor cycling
• Higher air use
• Poor launcher performance

Replacing damaged seals can help restore normal operation.
