Tool inspired by Master Airgun Tuner Ernest Rowe, this Delrin tool will help install your valve seat into any FX Airgun. It is made from Delrin as to not damage the sealing surface of your valveseat while pressing the seat into place.
Sized for 4.5mm, 5.5mm, 5.8mm and 6.3mm valveseats.
**Does NOT Work on FX Streamline without modification**
