<p>SP-P2 trigger valve assembly part number is 877-335 875-638, SP-P3 plunger valve part number is 884-111.SP-P2 SP-P3 Trigger and plunger valve kit fit for NR83A NR83A2 NR83A2(S) NR83A3.</p> <p>The plunger valve is crafted from brass, while the trigger valve's main body is constructed with High-quality material. It exhibits a superior luster and texture, exceptional robustness, as well as excellent resistance to moisture and rust, ensuring long-lasting durability.</p> <p>The plunger valve assembly regulates the motion of the driver or piston within the nail , enabling compressed air to propel the driver forward for efficient nail penetration into materials. The effective sealing of the plunger valve is crucial in maintaining the necessary air pressure for proper nail activation.</p> <p>The trigger valve assembly regulates the compressed air flow to both the plunger valve and driver. Activation of the trigger initiates the opening of the valve, allowing compressed air to be directed towards the plunger valve. Prior to pulling the trigger, it is necessary for it to be pressed against a work . Regular cleaning and lubrication are essential in ensuring optimal functionality of these components and prolonging their lifespan.</p> <p>Colour:As Shown</p> <p>Material:brass</p> <p>Package Contents:</p> <p>1set x framing nailer</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
