If you’re using the stock hose and trigger gun with factory replacement O-rings, it may be that you need to lube the o-ring up a bit.
Here are a few helpful tips:
- Ensure the gun’s M22 x 15mm male adapter is clean and free of any debris or mineral build up.
- Apply a small amount of petroleum jelly to the hose O-ring to help with installation.
- While pulling back the collar, insert the M22 x 15mm female adapter from the hose into the gun.
- Gently wiggle the connection as you push it in to ensure it seats properly.
- finally once it seats, thread the collar on to the trigger gun.
This should help create a proper seal and allow for a threaded connection.
