This is a single OEM drain valve for an air compressor. A drain valve is a small device that is usually located at the bottom of the compressor air receiver. The drain valve can be opened or closed, and this allows water to exit the tank. Water builds up if air is left in the tank for an extended period of time, and if left for too long, it can start to rust out the inside of the tank and the drain valve can become clogged with rust or start to corrode. You should be draining the tank each time you use your air compressor to stop this from happening. This is a very quick and simple repair. Use a wrench to remove the old drain valve, and thread the new one into place by hand.

This firing valve piston assembly is a critical component of the pneumatic firing system, controlling the flow and release of compressed air required to drive fasteners and reset the tool after each firing cycle. Constructed from durable metal, engineered plastics, and high-quality rubber seals, the assembly helps maintain proper internal air pressure while ensuring smooth, consistent tool operation. When the trigger is activated, the valve assembly directs compressed air through the firing system to drive the piston and fastener, then helps manage exhaust airflow to prepare the tool for the next cycle. Replacing a worn, damaged, or leaking firing valve assembly can help resolve issues such as continuous air leaks from the exhaust, weak driving power, inconsistent firing, loss of pressure, or failure to cycle properly. Installation typically involves removing the top cap assembly, replacing the existing valve assembly, and reassembling the tool using standard hand tools. For best results, inspect the head valve, O-rings, cylinder sleeve, piston, and related sealing components for wear or damage and replace any faulty parts as needed to ensure reliable performance and long-lasting pneumatic operation.

This genuine OEM trigger valve in your nailer or stapler works in conjunction with the head valve. When you press the trigger valve, it creates a pressure difference between the air reservoir and the cylinder and causes the head valve to open and release compressed air to drive the nail or staple into the material you are working on. It is commonly found in the handle or grip area of the tool. If the trigger becomes stiff or difficult to press, the trigger valve may be damaged. To replace the trigger valve, begin by removing the magazine and retainer caps for the nosepiece guard. Take out the nosepiece from the housing and remove the roll pins securing the piston. Pull back the plastic guard on the housing, detach the strap securing the piston, and extract the piston from your tool. You can access and remove the trigger valve by taking out the O-ring and the pin that holds the trigger in place. Before reassembling the housing, remember to apply lubricant to the O-rings.

This item is an authentic Bostitch replacement part that has been sourced from the original manufacturer to be used with pneumatic nailers. The trigger valve works with the plunger to shift pressurized air above the piston to drive it downward and to allow pressure to move back below the piston to keep in the up position. This item is available as an individual replacement part.

This unthreaded trigger valve assembly is a genuine OEM assembly used in nailers. It includes the trigger valve, 1 rubber washer, and 3 roll pins. The trigger valve controls the flow of air in the tool which drives the piston and creates the nailing action. If the valve becomes stuck, the seals wear down, or the trigger breaks the nailer will leak air, struggle to fire, or not fire at all. Begin the repair by switching off the tool and using a push pin to remove the trigger. Remove the roll pins that secure the trigger valve and pull the trigger valve out of the housing. Insert the new valve into the housing, install the pins to hold it in place, and secure the stay pin with the washer.
