Our nailer return springs are made by manufacturer Aulpq and are made of memory metal that is treated with corrosion protection and is durable.

When you feel that your nail gun is not working smoothly, the rebound speed is slower, and it cannot be reset quickly, you should try replacing your nailer return spring.

When you use your nailer gun for a long time and high intensity, it will cause metal fatigue of the nailer return spring, resulting in insufficient elasticity to work properly, our recommendation is to replace it regularly!
