Installation Tips
- Verify the model number of your gun before installation (G15 or G40 variants as listed above).
- Clean the sealing area thoroughly to remove any old material or debris.
- Ensure the washer seats flat — any tilting can cause leaks or premature failure.
- If the gun has seen heavy usage, consider replacing related seals or o-rings simultaneously for best performance.
