Porter Cable Piston Bumper (part number 886113). On nailers, a piston bumper is employed. This part is compatible with model number RN175. This piston bumper is also used on a stapler, as you can see below. The dimensions are 5 inches long, 5 inches wide, and 4 inches high. This item has a package weight of four pounds. Porter-Cable has a long and illustrious history of innovation, and the company has been responsible for numerous firsts in the power tool industry. In addition to designing and manufacturing power tools for the professional woodworking industry, the company also distributes pneumatic power tools and compressors as well as pressure washers, generators, and related accessories for the commercial/residential construction, plumbing, and electrical markets.
This is the part of the tool that fails the most frequently.
If you maintain the tool or only use it occasionally, and the tool decides to stop working one day, this is the part you should purchase. This part will correct the “non return” problem, which occurs when the piston moves forward but does not return completely to its original position. This results in nail misfires because the anvil does not fully return to its original position, allowing the next nail to load into position. Because the internal condition of my tool was excellent, I did not need to purchase a costly o ring rebuild kit, which would have been unnecessary.
