Product Details
Brand: Hitachi
Part Number: 878-723


O-rings can be made from a variety of materials including polyurethane, silicone and neoprene. O-rings provide a seal between two components to keep out air or fluid. In a pneumatic nail gun, o-rings provide a seal as well as to allow components such as the piston and head valve to actuate and move so there is no metal-on-metal friction. New o-rings must be lubricated with grease when installed.
