Browse aftermarket plugs and stops for skid steer loaders, compact track loaders, and excavators, including oil gauge and level plugs, bleed plugs, threaded port plugs and caps, glow plugs, door stops, and rubber bumpers.
Match your part by OEM part number and thread size. Details are listed on each product page.
This page holds two unrelated groups that share a name, and knowing which one you are after saves a wrong order. Plugs seal or close something: a threaded port, a fluid level opening, a bleed point, or a combustion chamber in the case of a glow plug. Stops limit movement: a door stop or a rubber bumper that keeps two parts from meeting. Common replacements include the oil gauge plugs replacing OEM 6969804 and Kubota 1C010-36550, 19640-33640, and 16414-33640, the bleed plug replacing OEM 6658180, the glow plug replacing OEM 6655233, the plugs replacing OEM 47K2, 6657719, 6655160, and 7008393, the plug cap for excavators replacing OEM 7164359, the cap replacing OEM 6664224, the rear door stop replacing OEM 7322368, and the rubber bumper replacing OEM 7226984.
Oil gauge plugs are more important than their price suggests. On a gearbox, chaincase, or final drive, the plug hole is the level itself: correct fill is oil sitting at the bottom edge of that opening, not a mark on a dipstick. A plug left loose, cross-threaded, or replaced with the wrong thread turns a sealed reservoir into a slow leak that empties an assembly nobody thinks to check.
Level and drain plugs set and hold fluid level, and many carry a sealing washer or a tapered thread that does the sealing. Bleed plugs sit at the deliberate high point of a circuit so trapped air can be released, which is why their position matters more than their size.
Port plugs and caps close unused ports and protect threads and couplers from dirt. A capped port that has lost its cap is an open invitation for contamination on a machine that works in dust. Glow plugs are cold start heaters rather than seals and appear here alongside the engine and fuel system pages.
Door stops and rubber bumpers limit travel and absorb contact. They are the parts that quietly protect panels, glass, and hinges, and when one is missing the damage lands on something considerably more expensive than the stop.
